Add code to compute the correct number of valid rendertargets to prevent an issue during PSO creation when NumRenderTargets is >0, but none of the formats are valid (all formats are DXGI_UNKNOWN) #jira UE-40332 Change 3251141 on 2017/01/09 by Ben.Woodhouse Duplicated from Fortnite CL 3243458: D3D12 memory optimization - The d3d12 buddy suballocator is very wasteful for allocations above 4KB, but the vast majority of allocations are smaller . In the default buffer allocator this was causing 149MB of waste in 340MB of allocations. Moving the max allocation size threshold down to 4KB from 512KB saved 100MB of memory wastage memory. On PC, buffers are 64KB aligned, so we need the threshold to be higher to avoid additional wastage. Add PIX memory tracking instrumentation for buddy allocators so we can track the memory properly in PIX Change 3251142 on 2017/01/09 by Ben.Woodhouse Duplicated from Fortnite 3243496 memory optimisation: use NULL-terminated ansi strings instead of unicode FStrings for symbols, saving 118MB. Previously the strings were loaded from disk as ansi and then converted to FStrings (slowly), before finally being converted them back to ansi strings before being used. In addition to reducing memory overhead, this change reduces complexity and improves startup time. Change 3252323 on 2017/01/10 by Rolando.Caloca DR - Gfx async PSO creation prep Change 3252474 on 2017/01/10 by Daniel.Wright Added 'Compile Unreal Lightmass' to error message Change 3252589 on 2017/01/10 by Daniel.Wright Back out bulk data for distance fields from cl 3241990 which causes distance fields to be corrupt in Fortnite Change 3252790 on 2017/01/10 by Daniel.Wright Added InscatteringColorCubemapAngle to exponential height fog Change 3252843 on 2017/01/10 by Uriel.Doyon Propper fix for UE-40211, where texture streaming bound defrag and async tasks could interact in coherent ways. The bound defrag is now done outside of the async work logic. Change 3252866 on 2017/01/10 by Mark.Satterthwaite Fix Metal shader pipeline hash collisions caused by deferring MTLFunction construction until PrepareToDraw so that we may use Function-Constants to specialise the shader source without generating additional permutations. This is required to generate proper tessellation shaders which are specialised against the index-buffer usage & type (none, uint16, uint32). While we're here amend the hash functions to make better use of the existing hash functions to improve the distribution and hopefully reduce the possibility of collisions in future. #jira UE-40357 Change 3254511 on 2017/01/11 by Rolando.Caloca DR - PSO stats Change 3255958 on 2017/01/12 by Mark.Satterthwaite Reimplement RQT_AbsoluteTime for Metal - pretty sure I did this before, but somehow it got lost. When a RQT_AbsoluteTime is inserted into the command-stream, insert a command-buffer completion handler to record the time of completion & submit the command-buffer immediately. This breaks command-buffers so is noticeably slower and if inserted in a pass that can't be restarted will fail but is currently the only option available. This is sufficient to support the GPUBenchmark used by Scalability. To make this more efficient I've refactored the FMetalCommandBufferFence implementation so that we use a single shared-ptr object containing the command-buffer and a dispatch semaphore, rather than allocating one for each query. The semaphore allows for timed-waits where previously we'd block until completion, unlike the other APIs that report failure after a fixed interval (2s for RQT_AbsoluteTime, otherwise 0.5s). Sadly not all drivers support this abuse of the Metal API, so replace the GL-based workaround for not having time queries with one that just guesses based on RHI device details. Radars will be filed. #jira UE-40554 Change 3256329 on 2017/01/12 by Olaf.Piesche #jira UE-38615 Assert shouldn't be necessary; in fact, it causes a crash when exporting emitters, since in that case we're changing the template at runtime. Change 3256371 on 2017/01/12 by Uriel.Doyon Reenabled texture streaming bound defrag as the fix is in CL 3252843 Change 3257032 on 2017/01/13 by Daniel.Wright Added fastClamp to fastmath.usf Change 3257111 on 2017/01/13 by Daniel.Wright Disabled bAffectDistanceFieldLighting on DefaultPawn, fixes VisualizeMeshDistanceFields in game Change 3257112 on 2017/01/13 by Daniel.Wright DFAO optimizations * Changed the culling algorithm to produce a list of intersecting screen tiles for each object, instead of the other way around. Each tile / object intersection gets its own cone tracing thread group so wavefronts are much smaller and scheduled better. 3.63ms -> 3.48ms (.15ms) * Replace slow instructions in inner loop with fast approximations (exp2 -> sqr + 1, rcpFast, lengthFast) 3.25ms -> 3.09ms (.16ms) * Moved transform from world to local space out of the inner loop (sample position constructed from local space position + direction) 3.09ms -> 3.04ms * Compute shader for ClearUAV 3.04ms -> 2.62ms (.42ms) Change 3257113 on 2017/01/13 by Daniel.Wright Better distance field memory stats Change 3257326 on 2017/01/13 by Uriel.Doyon Workaround to support cases where several textures have the same lighting GUID. Change 3257448 on 2017/01/13 by Daniel.Wright Removed legacy features Distance Field Specular Occlusion, Distance Field Surface Cache AO, PreCullTriangles Change 3257616 on 2017/01/13 by Daniel.Wright Distance field mesh visualization now uses a cone containing the entire tile to cull objects with, making the results stable Change 3257657 on 2017/01/13 by Daniel.Wright Mesh distance fields are stored zlib compressed in memory until needed for uploading to GPU * 81Mb of backing memory -> 32Mb in GPUPerfTest, atlas upload time 29ms -> 893ms Change 3258063 on 2017/01/14 by Rolando.Caloca DR - vk - Refactor descriptor set reuse in prep for more changes Change 3258715 on 2017/01/16 by Daniel.Wright Added VisualizeGlobalDistanceField show flag Change 3258827 on 2017/01/16 by Daniel.Wright Global distance field update regions are clipped against others to reduce redundant updates. Change 3258959 on 2017/01/16 by Benjamin.Hyder Updating Planar Reflection example material in TM-Shadermodels Change 3259270 on 2017/01/16 by Daniel.Wright [Copy] 'r.MSAACount 1' now produces no MSAA or TAA. 'r.MSAACount 0' can be used to toggle TAA on for comparisons. Change 3259652 on 2017/01/16 by Uriel.Doyon Better support for static primitive becoming dynamic. Change 3260107 on 2017/01/17 by Ben.Woodhouse Fix FMonitoredProcess to prevent infinite loop in -nothreading mode #jira UE-40717 Change 3260594 on 2017/01/17 by Daniel.Wright Added a new global distance field (4x 128^3 clipmaps) which caches mostly static primitives (Mobility set to Static or Stationary) * The full global distance field inherits from the mostly static cache, so when a Movable primitive is modified, only other movable primitives in the vicinity need to be re-composited into the global distance field * Global distance field update cost with one large rotating object went from 2.5ms -> .2ms on 970GTX and 4.6ms -> .3ms. Worst case full volume update is mostly the same. * Adds 12Mb for the new volume textures Change 3260956 on 2017/01/17 by Daniel.Wright Structured buffers for DF object data * Full global distance field clipmap composite 3.0ms -> 2.0ms due to scalarized loads Change 3261296 on 2017/01/17 by Daniel.Wright Exposed MaxObjectsPerTile with 'r.AOMaxObjectsPerCullTile' and lowered the default from 512 to 256, saves 17Mb of object tile culling data structures Removed unnecessary UAV transitions preventing object and global cone tracing from overlapping, saves ~.1ms Change 3262036 on 2017/01/18 by Ben.Salem V0 of Perf monitor plugin for easily consumable stat csvs. With plugin enabled, enter PerformanceMonitor help into the console to get usage details. Change 3262056 on 2017/01/18 by Chris.Bunner Remove inverse tonemapping when rendering HDR output. #jira UE-40728 Change 3262661 on 2017/01/18 by Rolando.Caloca DR - Add missing SetStencilRef() and SetBlendFactor() on most RHIs - Fix hash for PSOs Change 3263674 on 2017/01/19 by Chris.Bunner PR #3144: Improved error messages (Contributed by DarkSlot) #jira UE-40835 Change 3264150 on 2017/01/19 by Ben.Woodhouse Add support for single threaded in FMonitoredProcess. Deprecated IsRunning() in favour of a new Update() method because polling IsRunning is not compatible with -nothreading mode #jira UE-40841 Change 3264153 on 2017/01/19 by Ben.Woodhouse Integrate latest changes from MS-DX12 CLs 3231395-3262526 - Added WinPixEventRuntime.tps - Includes PIX support, various optimizations (saved 1.3ms in testbed scene) CL 3262343: Fix depth testing on translucency not working correctly after cl 3231395. This change reapplies the D3D12RHI changes from CL 3231395 because those changes were lost when integrating from //Dev-Rendering/ but also includes the depth fixes: - Fix depth state not being in DEPTH_READ for use as depth read. The issue was HasDepthBits and HasStencilBits wern't intended for SRV formats and always returned false in the SRV case. CL 3231395: Update D3D12 RHI: - Fix deferred MSAA path in RHI - Add Pix3.h support - Cleanup SetName usage and remove it from shipping builds. - Fix fence reuse bug. We were signaling MAX UINT (-1) and then waiting for 0, which was always signaled. This change also removes the fence value reset code, there is no need to reset a fence to a previous value. - Use FPlatformAtomics::InterlockedIncrement instead of InterlockedIncrement64 - Use InterlockedIncrement() instead of _InterlockedIncrement() and use the FPlatformAtomics:: version. - Fix possible readback heap being evicted while in use. GetQueryData happens on the render thread and isn't tied to a command list so we should always have readback heaps resident. Change 3264251 on 2017/01/19 by Mark.Satterthwaite Modify some asserts in MetalRHI - technically using a store-action of ENoAction on Stencil buffers should make it invalid to restart a render-pass but on Mac it will work because ENoAction won't invalidate anything written. In future we need to use deferred store-actions in Metal so that we can "restart" passes while enforcing correct Load/Store actions. #jira UE-40803 Change 3264642 on 2017/01/19 by Daniel.Wright Raised GMaxShadowDepthBufferSizeX to max texture resolution on most platforms, was previously 4096. Change 3265330 on 2017/01/20 by Ben.Salem Stop performance plugin from building in Win32. #tests recompiled and preflighted Change 3265678 on 2017/01/20 by Marcus.Wassmer Fix bad declaration. #3055 Change 3266656 on 2017/01/20 by Mark.Satterthwaite Changes to the FShaderCache to restore it and extend it to optionally report on shader de-duplication when generating a binary shader cache (Console Variable: r.BinaryShaderCacheLogging). Duplicate & amend CL #3266053 from Trepka: Fixed issues with shader cache not working properly with Mac Metal (but it still requires -norhithread to work at all). Enabled the shader cache by default if RHI thread is disabled. Amend & integrate RCO's CL #3197085. Change 3267741 on 2017/01/23 by Rolando.Caloca DR - Detect duplicated shader and pipeline types Change 3268600 on 2017/01/23 by Uriel.Doyon Added missing r.Streaming.MaxEffectiveScreenSize config to base texture scability settings. Integrated CL 3227368 from Orion stream Enabled r.Streaming.UsePerTextureBias by default as this has been tested in Orion for several months. Fixed issue with the InvestigateTexture command which could return invalid reference depending on the timing, Added th MaxEffectiveScreenSize settings in the investigate texture command. Change 3269512 on 2017/01/24 by Richard.Wallis Fix for shader binary cache uncompress data size during internal shader log.

The allocator allocates non-contiguous ranges of pages and maps them onto a contiguous virtual address range. Unlike the previous implementation, this allocator frees pages for reuse when resources are destroyed Note: issues with deferred deallocation may prevent reuse in many cases - that will be addressed in the next stage Support for the old allocator is still available (for now) via the define NEW_ESRAM_ALLOCATOR #fyi rolando.caloca Change 3272616 on 2017/01/25 by Rolando.Caloca DR - Update shader version Change 3273138 on 2017/01/26 by Ben.Woodhouse Fix merge issue with MonitoredProcess.cpp (this arose from an integration made as an edit in dev-rendering, which confused perforce when the change was subsequently integrated from main) [CL 3274498 by Rolando Caloca in Main branch]

Distance Field AO is now evaluated on a screen grid and using a global distance field for far traces * Screen grid resolution is 1/8th of primary resolution, but with 4x temporal supersampling through jittering subsample positions. A longer history filter is required to hide the jittering which can increase ghosting. * The main benefit of doing cone tracing on a screen grid instead of the previous surface cache is that it's performance is generally constant regardless of camera movement or noisy geometry (foliage) * A global distance field is now used for cone traces after a certain distance, DFAO is 2-4x faster as a result. * The global distance field is composed of 4 128^3 clipmaps that follow the camera around * Clipmaps are scrolled so that only new or dirty regions are updated due to camera or object movement, with close to 0 average GPU cost. Worst case update cost (camera teleport) is 5ms on 7870. * The global distance field currently breaks Distance Field GI * Overall with these changes DFAO in a Fortnite level is 3.4ms on a 7870 (3.8ms on PS4), and 4.0ms in the Kite demo on 7870.

Added an incremental update in the last stage of the texture streaming update load to clear any pending work. Added an option "All" to the "BuildMateriaTexturelStreamingData" command to force rebuild everything. Change 3235317 on 2016/12/14 by Uriel.Doyon Removed timed primitives in the texture streaming since it was not used and there is now a fallback implementation in UPrimitiveComponent::GetStreamingTextureInfo.

Long-term the Metal tessellation code will need to be refactored so that the vertex shader stage is emitted as a separate shader from the hull shader stage as this but will keep cropping back up and continue to complicate the engine. #jira UE-39799 Change 3237490 on 2016/12/15 by Daniel.Wright Fixed ULandscapeComponent::GetUsedMaterials Change 3237597 on 2016/12/15 by Ben.Woodhouse Disable timestamp queries on pre-Maxwell nvidia hardware.

Added an incremental update in the last stage of the texture streaming update load to clear any pending work. Added an option "All" to the "BuildMateriaTexturelStreamingData" command to force rebuild everything. Change 3235317 on 2016/12/14 by Uriel.Doyon Removed timed primitives in the texture streaming since it was not used and there is now a fallback implementation in UPrimitiveComponent::GetStreamingTextureInfo.

Refactored the code to separate the concept or valid render-states in the cache from active render-states in the render-pass. Now it works as intended and will be needed for 4.15.

Long-term the Metal tessellation code will need to be refactored so that the vertex shader stage is emitted as a separate shader from the hull shader stage as this but will keep cropping back up and continue to complicate the engine. #jira UE-39799 Change 3237490 on 2016/12/15 by Daniel.Wright Fixed ULandscapeComponent::GetUsedMaterials Change 3237597 on 2016/12/15 by Ben.Woodhouse Disable timestamp queries on pre-Maxwell nvidia hardware. Local testing suggests that this is the major cause of instability in the UE4.14 release. It's possible that we could be more targeted by only excluding Fermi and older hardware, but identifying fermi hardware by device ID is difficult in practice, since the range overlaps with Kepler.

return JitterOffsets[SampleIndex] * GConeTraceDownsampleFactor;
Distance Field AO is now evaluated on a screen grid and using a global distance field for far traces * Screen grid resolution is 1/8th of primary resolution, but with 4x temporal supersampling through jittering subsample positions. A longer history filter is required to hide the jittering which can increase ghosting. * The main benefit of doing cone tracing on a screen grid instead of the previous surface cache is that it's performance is generally constant regardless of camera movement or noisy geometry (foliage) * A global distance field is now used for cone traces after a certain distance, DFAO is 2-4x faster as a result. * The global distance field is composed of 4 128^3 clipmaps that follow the camera around * Clipmaps are scrolled so that only new or dirty regions are updated due to camera or object movement, with close to 0 average GPU cost. Worst case update cost (camera teleport) is 5ms on 7870. * The global distance field currently breaks Distance Field GI * Overall with these changes DFAO in a Fortnite level is 3.4ms on a 7870 (3.8ms on PS4), and 4.0ms in the Kite demo on 7870.

Add code to compute the correct number of valid rendertargets to prevent an issue during PSO creation when NumRenderTargets is >0, but none of the formats are valid (all formats are DXGI_UNKNOWN) #jira UE-40332 Change 3251141 on 2017/01/09 by Ben.Woodhouse Duplicated from Fortnite CL 3243458: D3D12 memory optimization - The d3d12 buddy suballocator is very wasteful for allocations above 4KB, but the vast majority of allocations are smaller . In the default buffer allocator this was causing 149MB of waste in 340MB of allocations. Moving the max allocation size threshold down to 4KB from 512KB saved 100MB of memory wastage memory. On PC, buffers are 64KB aligned, so we need the threshold to be higher to avoid additional wastage. Add PIX memory tracking instrumentation for buddy allocators so we can track the memory properly in PIX Change 3251142 on 2017/01/09 by Ben.Woodhouse Duplicated from Fortnite 3243496 memory optimisation: use NULL-terminated ansi strings instead of unicode FStrings for symbols, saving 118MB. Previously the strings were loaded from disk as ansi and then converted to FStrings (slowly), before finally being converted them back to ansi strings before being used. In addition to reducing memory overhead, this change reduces complexity and improves startup time.

The bound defrag is now done outside of the async work logic. Change 3252866 on 2017/01/10 by Mark.Satterthwaite Fix Metal shader pipeline hash collisions caused by deferring MTLFunction construction until PrepareToDraw so that we may use Function-Constants to specialise the shader source without generating additional permutations. This is required to generate proper tessellation shaders which are specialised against the index-buffer usage & type (none, uint16, uint32). While we're here amend the hash functions to make better use of the existing hash functions to improve the distribution and hopefully reduce the possibility of collisions in future. #jira UE-40357 Change 3254511 on 2017/01/11 by Rolando.Caloca DR - PSO stats Change 3255958 on 2017/01/12 by Mark.Satterthwaite Reimplement RQT_AbsoluteTime for Metal - pretty sure I did this before, but somehow it got lost. When a RQT_AbsoluteTime is inserted into the command-stream, insert a command-buffer completion handler to record the time of completion & submit the command-buffer immediately. This breaks command-buffers so is noticeably slower and if inserted in a pass that can't be restarted will fail but is currently the only option available. This is sufficient to support the GPUBenchmark used by Scalability. To make this more efficient I've refactored the FMetalCommandBufferFence implementation so that we use a single shared-ptr object containing the command-buffer and a dispatch semaphore, rather than allocating one for each query. The semaphore allows for timed-waits where previously we'd block until completion, unlike the other APIs that report failure after a fixed interval (2s for RQT_AbsoluteTime, otherwise 0.5s). Sadly not all drivers support this abuse of the Metal API, so replace the GL-based workaround for not having time queries with one that just guesses based on RHI device details. Radars will be filed. #jira UE-40554 Change 3256329 on 2017/01/12 by Olaf.Piesche #jira UE-38615 Assert shouldn't be necessary; in fact, it causes a crash when exporting emitters, since in that case we're changing the template at runtime.

This change reapplies the D3D12RHI changes from CL 3231395 because those changes were lost when integrating from //Dev-Rendering/ but also includes the depth fixes: - Fix depth state not being in DEPTH_READ for use as depth read. The issue was HasDepthBits and HasStencilBits wern't intended for SRV formats and always returned false in the SRV case. CL 3231395: Update D3D12 RHI: - Fix deferred MSAA path in RHI - Add Pix3.h support - Cleanup SetName usage and remove it from shipping builds. - Fix fence reuse bug. We were signaling MAX UINT (-1) and then waiting for 0, which was always signaled. This change also removes the fence value reset code, there is no need to reset a fence to a previous value. - Use FPlatformAtomics::InterlockedIncrement instead of InterlockedIncrement64 - Use InterlockedIncrement() instead of _InterlockedIncrement() and use the FPlatformAtomics:: version. - Fix possible readback heap being evicted while in use. GetQueryData happens on the render thread and isn't tied to a command list so we should always have readback heaps resident. Change 3264251 on 2017/01/19 by Mark.Satterthwaite Modify some asserts in MetalRHI - technically using a store-action of ENoAction on Stencil buffers should make it invalid to restart a render-pass but on Mac it will work because ENoAction won't invalidate anything written. In future we need to use deferred store-actions in Metal so that we can "restart" passes while enforcing correct Load/Store actions. #jira UE-40803 Change 3264642 on 2017/01/19 by Daniel.Wright Raised GMaxShadowDepthBufferSizeX to max texture resolution on most platforms, was previously 4096.

Distance Field AO is now evaluated on a screen grid and using a global distance field for far traces * Screen grid resolution is 1/8th of primary resolution, but with 4x temporal supersampling through jittering subsample positions. A longer history filter is required to hide the jittering which can increase ghosting. * The main benefit of doing cone tracing on a screen grid instead of the previous surface cache is that it's performance is generally constant regardless of camera movement or noisy geometry (foliage) * A global distance field is now used for cone traces after a certain distance, DFAO is 2-4x faster as a result. * The global distance field is composed of 4 128^3 clipmaps that follow the camera around * Clipmaps are scrolled so that only new or dirty regions are updated due to camera or object movement, with close to 0 average GPU cost. Worst case update cost (camera teleport) is 5ms on 7870. * The global distance field currently breaks Distance Field GI * Overall with these changes DFAO in a Fortnite level is 3.4ms on a 7870 (3.8ms on PS4), and 4.0ms in the Kite demo on 7870.

Add code to compute the correct number of valid rendertargets to prevent an issue during PSO creation when NumRenderTargets is >0, but none of the formats are valid (all formats are DXGI_UNKNOWN) #jira UE-40332 Change 3251141 on 2017/01/09 by Ben.Woodhouse Duplicated from Fortnite CL 3243458: D3D12 memory optimization - The d3d12 buddy suballocator is very wasteful for allocations above 4KB, but the vast majority of allocations are smaller . In the default buffer allocator this was causing 149MB of waste in 340MB of allocations. Moving the max allocation size threshold down to 4KB from 512KB saved 100MB of memory wastage memory. On PC, buffers are 64KB aligned, so we need the threshold to be higher to avoid additional wastage. Add PIX memory tracking instrumentation for buddy allocators so we can track the memory properly in PIX Change 3251142 on 2017/01/09 by Ben.Woodhouse Duplicated from Fortnite 3243496 memory optimisation: use NULL-terminated ansi strings instead of unicode FStrings for symbols, saving 118MB. Previously the strings were loaded from disk as ansi and then converted to FStrings (slowly), before finally being converted them back to ansi strings before being used. In addition to reducing memory overhead, this change reduces complexity and improves startup time. Change 3252323 on 2017/01/10 by Rolando.Caloca DR - Gfx async PSO creation prep Change 3252474 on 2017/01/10 by Daniel.Wright Added 'Compile Unreal Lightmass' to error message Change 3252589 on 2017/01/10 by Daniel.Wright Back out bulk data for distance fields from cl 3241990 which causes distance fields to be corrupt in Fortnite Change 3252790 on 2017/01/10 by Daniel.Wright Added InscatteringColorCubemapAngle to exponential height fog Change 3252843 on 2017/01/10 by Uriel.Doyon Propper fix for UE-40211, where texture streaming bound defrag and async tasks could interact in coherent ways. The bound defrag is now done outside of the async work logic. Change 3252866 on 2017/01/10 by Mark.Satterthwaite Fix Metal shader pipeline hash collisions caused by deferring MTLFunction construction until PrepareToDraw so that we may use Function-Constants to specialise the shader source without generating additional permutations. This is required to generate proper tessellation shaders which are specialised against the index-buffer usage & type (none, uint16, uint32). While we're here amend the hash functions to make better use of the existing hash functions to improve the distribution and hopefully reduce the possibility of collisions in future. #jira UE-40357 Change 3254511 on 2017/01/11 by Rolando.Caloca DR - PSO stats Change 3255958 on 2017/01/12 by Mark.Satterthwaite Reimplement RQT_AbsoluteTime for Metal - pretty sure I did this before, but somehow it got lost. When a RQT_AbsoluteTime is inserted into the command-stream, insert a command-buffer completion handler to record the time of completion & submit the command-buffer immediately. This breaks command-buffers so is noticeably slower and if inserted in a pass that can't be restarted will fail but is currently the only option available. This is sufficient to support the GPUBenchmark used by Scalability. To make this more efficient I've refactored the FMetalCommandBufferFence implementation so that we use a single shared-ptr object containing the command-buffer and a dispatch semaphore, rather than allocating one for each query. The semaphore allows for timed-waits where previously we'd block until completion, unlike the other APIs that report failure after a fixed interval (2s for RQT_AbsoluteTime, otherwise 0.5s). Sadly not all drivers support this abuse of the Metal API, so replace the GL-based workaround for not having time queries with one that just guesses based on RHI device details. Radars will be filed. #jira UE-40554 Change 3256329 on 2017/01/12 by Olaf.Piesche #jira UE-38615 Assert shouldn't be necessary; in fact, it causes a crash when exporting emitters, since in that case we're changing the template at runtime.

Distance Field AO is now evaluated on a screen grid and using a global distance field for far traces * Screen grid resolution is 1/8th of primary resolution, but with 4x temporal supersampling through jittering subsample positions. A longer history filter is required to hide the jittering which can increase ghosting. * The main benefit of doing cone tracing on a screen grid instead of the previous surface cache is that it's performance is generally constant regardless of camera movement or noisy geometry (foliage) * A global distance field is now used for cone traces after a certain distance, DFAO is 2-4x faster as a result. * The global distance field is composed of 4 128^3 clipmaps that follow the camera around * Clipmaps are scrolled so that only new or dirty regions are updated due to camera or object movement, with close to 0 average GPU cost. Worst case update cost (camera teleport) is 5ms on 7870. * The global distance field currently breaks Distance Field GI * Overall with these changes DFAO in a Fortnite level is 3.4ms on a 7870 (3.8ms on PS4), and 4.0ms in the Kite demo on 7870.

Add code to compute the correct number of valid rendertargets to prevent an issue during PSO creation when NumRenderTargets is >0, but none of the formats are valid (all formats are DXGI_UNKNOWN) #jira UE-40332 Change 3251141 on 2017/01/09 by Ben.Woodhouse Duplicated from Fortnite CL 3243458: D3D12 memory optimization - The d3d12 buddy suballocator is very wasteful for allocations above 4KB, but the vast majority of allocations are smaller . In the default buffer allocator this was causing 149MB of waste in 340MB of allocations. Moving the max allocation size threshold down to 4KB from 512KB saved 100MB of memory wastage memory. On PC, buffers are 64KB aligned, so we need the threshold to be higher to avoid additional wastage. Add PIX memory tracking instrumentation for buddy allocators so we can track the memory properly in PIX Change 3251142 on 2017/01/09 by Ben.Woodhouse Duplicated from Fortnite 3243496 memory optimisation: use NULL-terminated ansi strings instead of unicode FStrings for symbols, saving 118MB. Previously the strings were loaded from disk as ansi and then converted to FStrings (slowly), before finally being converted them back to ansi strings before being used. In addition to reducing memory overhead, this change reduces complexity and improves startup time. Change 3252323 on 2017/01/10 by Rolando.Caloca DR - Gfx async PSO creation prep Change 3252474 on 2017/01/10 by Daniel.Wright Added 'Compile Unreal Lightmass' to error message Change 3252589 on 2017/01/10 by Daniel.Wright Back out bulk data for distance fields from cl 3241990 which causes distance fields to be corrupt in Fortnite Change 3252790 on 2017/01/10 by Daniel.Wright Added InscatteringColorCubemapAngle to exponential height fog Change 3252843 on 2017/01/10 by Uriel.Doyon Propper fix for UE-40211, where texture streaming bound defrag and async tasks could interact in coherent ways. The bound defrag is now done outside of the async work logic. Change 3252866 on 2017/01/10 by Mark.Satterthwaite Fix Metal shader pipeline hash collisions caused by deferring MTLFunction construction until PrepareToDraw so that we may use Function-Constants to specialise the shader source without generating additional permutations. This is required to generate proper tessellation shaders which are specialised against the index-buffer usage & type (none, uint16, uint32). While we're here amend the hash functions to make better use of the existing hash functions to improve the distribution and hopefully reduce the possibility of collisions in future. #jira UE-40357 Change 3254511 on 2017/01/11 by Rolando.Caloca DR - PSO stats Change 3255958 on 2017/01/12 by Mark.Satterthwaite Reimplement RQT_AbsoluteTime for Metal - pretty sure I did this before, but somehow it got lost. When a RQT_AbsoluteTime is inserted into the command-stream, insert a command-buffer completion handler to record the time of completion & submit the command-buffer immediately. This breaks command-buffers so is noticeably slower and if inserted in a pass that can't be restarted will fail but is currently the only option available. This is sufficient to support the GPUBenchmark used by Scalability. To make this more efficient I've refactored the FMetalCommandBufferFence implementation so that we use a single shared-ptr object containing the command-buffer and a dispatch semaphore, rather than allocating one for each query. The semaphore allows for timed-waits where previously we'd block until completion, unlike the other APIs that report failure after a fixed interval (2s for RQT_AbsoluteTime, otherwise 0.5s). Sadly not all drivers support this abuse of the Metal API, so replace the GL-based workaround for not having time queries with one that just guesses based on RHI device details. Radars will be filed. #jira UE-40554 Change 3256329 on 2017/01/12 by Olaf.Piesche #jira UE-38615 Assert shouldn't be necessary; in fact, it causes a crash when exporting emitters, since in that case we're changing the template at runtime.

Each tile / object intersection gets its own cone tracing thread group so wavefronts are much smaller and scheduled better. 3.63ms -> 3.48ms (.15ms) * Replace slow instructions in inner loop with fast approximations (exp2 -> sqr + 1, rcpFast, lengthFast) 3.25ms -> 3.09ms (.16ms) * Moved transform from world to local space out of the inner loop (sample position constructed from local space position + direction) 3.09ms -> 3.04ms * Compute shader for ClearUAV 3.04ms -> 2.62ms (.42ms) Change 3257113 on 2017/01/13 by Daniel.Wright Better distance field memory stats Change 3257326 on 2017/01/13 by Uriel.Doyon Workaround to support cases where several textures have the same lighting GUID.

Worst case full volume update is mostly the same. * Adds 12Mb for the new volume textures Change 3260956 on 2017/01/17 by Daniel.Wright Structured buffers for DF object data * Full global distance field clipmap composite 3.0ms -> 2.0ms due to scalarized loads Change 3261296 on 2017/01/17 by Daniel.Wright Exposed MaxObjectsPerTile with 'r.AOMaxObjectsPerCullTile' and lowered the default from 512 to 256, saves 17Mb of object tile culling data structures Removed unnecessary UAV transitions preventing object and global cone tracing from overlapping, saves ~.1ms Change 3262036 on 2017/01/18 by Ben.Salem V0 of Perf monitor plugin for easily consumable stat csvs. With plugin enabled, enter PerformanceMonitor help into the console to get usage details. Change 3262056 on 2017/01/18 by Chris.Bunner Remove inverse tonemapping when rendering HDR output. #jira UE-40728 Change 3262661 on 2017/01/18 by Rolando.Caloca DR - Add missing SetStencilRef() and SetBlendFactor() on most RHIs - Fix hash for PSOs Change 3263674 on 2017/01/19 by Chris.Bunner PR #3144: Improved error messages (Contributed by DarkSlot) #jira UE-40835 Change 3264150 on 2017/01/19 by Ben.Woodhouse Add support for single threaded in FMonitoredProcess. Deprecated IsRunning() in favour of a new Update() method because polling IsRunning is not compatible with -nothreading mode #jira UE-40841 Change 3264153 on 2017/01/19 by Ben.Woodhouse Integrate latest changes from MS-DX12 CLs 3231395-3262526 - Added WinPixEventRuntime.tps - Includes PIX support, various optimizations (saved 1.3ms in testbed scene) CL 3262343: Fix depth testing on translucency not working correctly after cl 3231395. This change reapplies the D3D12RHI changes from CL 3231395 because those changes were lost when integrating from //Dev-Rendering/ but also includes the depth fixes: - Fix depth state not being in DEPTH_READ for use as depth read. The issue was HasDepthBits and HasStencilBits wern't intended for SRV formats and always returned false in the SRV case. CL 3231395: Update D3D12 RHI: - Fix deferred MSAA path in RHI - Add Pix3.h support - Cleanup SetName usage and remove it from shipping builds. - Fix fence reuse bug. We were signaling MAX UINT (-1) and then waiting for 0, which was always signaled. This change also removes the fence value reset code, there is no need to reset a fence to a previous value. - Use FPlatformAtomics::InterlockedIncrement instead of InterlockedIncrement64 - Use InterlockedIncrement() instead of _InterlockedIncrement() and use the FPlatformAtomics:: version. - Fix possible readback heap being evicted while in use. GetQueryData happens on the render thread and isn't tied to a command list so we should always have readback heaps resident. Change 3264251 on 2017/01/19 by Mark.Satterthwaite Modify some asserts in MetalRHI - technically using a store-action of ENoAction on Stencil buffers should make it invalid to restart a render-pass but on Mac it will work because ENoAction won't invalidate anything written. In future we need to use deferred store-actions in Metal so that we can "restart" passes while enforcing correct Load/Store actions. #jira UE-40803 Change 3264642 on 2017/01/19 by Daniel.Wright Raised GMaxShadowDepthBufferSizeX to max texture resolution on most platforms, was previously 4096.

Duplicate & amend CL #3266053 from Trepka: Fixed issues with shader cache not working properly with Mac Metal (but it still requires -norhithread to work at all). Enabled the shader cache by default if RHI thread is disabled. Amend & integrate RCO's CL #3197085.

Update to AGS 5.0.5. Partial code tidy up. Change 3310187 on 2017/02/17 by Chris.Bunner Preserve constant expressions rather than always casting after translating a material attribute. Losing the notion of constant means we can't correctly detect used properties and falsely enable e.g. PDO. Happened because of the incorrect component masks in BreakMaterialNodes which then had to be downcast to the correct type which is done as an inline fragment rather than swizzle expression. #jira UE-41594 Change 3310215 on 2017/02/17 by Chris.Bunner Prevent SpeedTree node compiling for skeletal meshes (not supported as uses more UV sets than available).

Change 3333721 on 2017/03/06 by David.Hill DecalProxy: Copy float FadeScreenSize to FDeferredDecalProxy for use in the render thread. This avoids pointer chasing to the UDecalComponent (game thread component). Change 3333772 on 2017/03/06 by Daniel.Wright [Copy] Scene motion blur data is only updated for the main renderer frames.

All properties are in world space densities. * Particle systems using the Volume domain are voxelized based on their ParticlePosition and ParticleRadius * Volumetric fog integration is now energy conservative - scattering is integrated against transmission over the depth of each slice. * Added bOverrideLightColorsWithFogInscatteringColors to exponential height fog, which can be enabled to make Volumetric Fog match Height fog more closely Change 3334134 on 2017/03/06 by Daniel.Wright [Copy from Michael Trepka] Added Embree 2.14.0 and changed MeshUtilities to use it as this solves issues with Embree leaking TLS keys. UnrealLightmass is still using older Embree 2.7.0 until we can find time to properly test it with the new version. Also, invalidated distance field DDC to force it to rebuild with updated Embree.

Distance Field AO is now evaluated on a screen grid and using a global distance field for far traces * Screen grid resolution is 1/8th of primary resolution, but with 4x temporal supersampling through jittering subsample positions. A longer history filter is required to hide the jittering which can increase ghosting. * The main benefit of doing cone tracing on a screen grid instead of the previous surface cache is that it's performance is generally constant regardless of camera movement or noisy geometry (foliage) * A global distance field is now used for cone traces after a certain distance, DFAO is 2-4x faster as a result. * The global distance field is composed of 4 128^3 clipmaps that follow the camera around * Clipmaps are scrolled so that only new or dirty regions are updated due to camera or object movement, with close to 0 average GPU cost. Worst case update cost (camera teleport) is 5ms on 7870. * The global distance field currently breaks Distance Field GI * Overall with these changes DFAO in a Fortnite level is 3.4ms on a 7870 (3.8ms on PS4), and 4.0ms in the Kite demo on 7870.

A longer history filter is required to hide the jittering which can increase ghosting. * The main benefit of doing cone tracing on a screen grid instead of the previous surface cache is that it's performance is generally constant regardless of camera movement or noisy geometry (foliage) * A global distance field is now used for cone traces after a certain distance, DFAO is 2-4x faster as a result. * The global distance field is composed of 4 128^3 clipmaps that follow the camera around * Clipmaps are scrolled so that only new or dirty regions are updated due to camera or object movement, with close to 0 average GPU cost. Worst case update cost (camera teleport) is 5ms on 7870. * The global distance field currently breaks Distance Field GI * Overall with these changes DFAO in a Fortnite level is 3.4ms on a 7870 (3.8ms on PS4), and 4.0ms in the Kite demo on 7870.

Add code to compute the correct number of valid rendertargets to prevent an issue during PSO creation when NumRenderTargets is >0, but none of the formats are valid (all formats are DXGI_UNKNOWN) #jira UE-40332 Change 3251141 on 2017/01/09 by Ben.Woodhouse Duplicated from Fortnite CL 3243458: D3D12 memory optimization - The d3d12 buddy suballocator is very wasteful for allocations above 4KB, but the vast majority of allocations are smaller . In the default buffer allocator this was causing 149MB of waste in 340MB of allocations. Moving the max allocation size threshold down to 4KB from 512KB saved 100MB of memory wastage memory. On PC, buffers are 64KB aligned, so we need the threshold to be higher to avoid additional wastage. Add PIX memory tracking instrumentation for buddy allocators so we can track the memory properly in PIX Change 3251142 on 2017/01/09 by Ben.Woodhouse Duplicated from Fortnite 3243496 memory optimisation: use NULL-terminated ansi strings instead of unicode FStrings for symbols, saving 118MB. Previously the strings were loaded from disk as ansi and then converted to FStrings (slowly), before finally being converted them back to ansi strings before being used. In addition to reducing memory overhead, this change reduces complexity and improves startup time. Change 3252323 on 2017/01/10 by Rolando.Caloca DR - Gfx async PSO creation prep Change 3252474 on 2017/01/10 by Daniel.Wright Added 'Compile Unreal Lightmass' to error message Change 3252589 on 2017/01/10 by Daniel.Wright Back out bulk data for distance fields from cl 3241990 which causes distance fields to be corrupt in Fortnite Change 3252790 on 2017/01/10 by Daniel.Wright Added InscatteringColorCubemapAngle to exponential height fog Change 3252843 on 2017/01/10 by Uriel.Doyon Propper fix for UE-40211, where texture streaming bound defrag and async tasks could interact in coherent ways. The bound defrag is now done outside of the async work logic. Change 3252866 on 2017/01/10 by Mark.Satterthwaite Fix Metal shader pipeline hash collisions caused by deferring MTLFunction construction until PrepareToDraw so that we may use Function-Constants to specialise the shader source without generating additional permutations. This is required to generate proper tessellation shaders which are specialised against the index-buffer usage & type (none, uint16, uint32). While we're here amend the hash functions to make better use of the existing hash functions to improve the distribution and hopefully reduce the possibility of collisions in future. #jira UE-40357 Change 3254511 on 2017/01/11 by Rolando.Caloca DR - PSO stats Change 3255958 on 2017/01/12 by Mark.Satterthwaite Reimplement RQT_AbsoluteTime for Metal - pretty sure I did this before, but somehow it got lost. When a RQT_AbsoluteTime is inserted into the command-stream, insert a command-buffer completion handler to record the time of completion & submit the command-buffer immediately. This breaks command-buffers so is noticeably slower and if inserted in a pass that can't be restarted will fail but is currently the only option available. This is sufficient to support the GPUBenchmark used by Scalability. To make this more efficient I've refactored the FMetalCommandBufferFence implementation so that we use a single shared-ptr object containing the command-buffer and a dispatch semaphore, rather than allocating one for each query. The semaphore allows for timed-waits where previously we'd block until completion, unlike the other APIs that report failure after a fixed interval (2s for RQT_AbsoluteTime, otherwise 0.5s). Sadly not all drivers support this abuse of the Metal API, so replace the GL-based workaround for not having time queries with one that just guesses based on RHI device details. Radars will be filed. #jira UE-40554 Change 3256329 on 2017/01/12 by Olaf.Piesche #jira UE-38615 Assert shouldn't be necessary; in fact, it causes a crash when exporting emitters, since in that case we're changing the template at runtime.

Each tile / object intersection gets its own cone tracing thread group so wavefronts are much smaller and scheduled better. 3.63ms -> 3.48ms (.15ms) * Replace slow instructions in inner loop with fast approximations (exp2 -> sqr + 1, rcpFast, lengthFast) 3.25ms -> 3.09ms (.16ms) * Moved transform from world to local space out of the inner loop (sample position constructed from local space position + direction) 3.09ms -> 3.04ms * Compute shader for ClearUAV 3.04ms -> 2.62ms (.42ms) Change 3257113 on 2017/01/13 by Daniel.Wright Better distance field memory stats Change 3257326 on 2017/01/13 by Uriel.Doyon Workaround to support cases where several textures have the same lighting GUID.

Change 3262056 on 2017/01/18 by Chris.Bunner Remove inverse tonemapping when rendering HDR output. #jira UE-40728 Change 3262661 on 2017/01/18 by Rolando.Caloca DR - Add missing SetStencilRef() and SetBlendFactor() on most RHIs - Fix hash for PSOs Change 3263674 on 2017/01/19 by Chris.Bunner PR #3144: Improved error messages (Contributed by DarkSlot) #jira UE-40835 Change 3264150 on 2017/01/19 by Ben.Woodhouse Add support for single threaded in FMonitoredProcess.

This change reapplies the D3D12RHI changes from CL 3231395 because those changes were lost when integrating from //Dev-Rendering/ but also includes the depth fixes: - Fix depth state not being in DEPTH_READ for use as depth read. The issue was HasDepthBits and HasStencilBits wern't intended for SRV formats and always returned false in the SRV case. CL 3231395: Update D3D12 RHI: - Fix deferred MSAA path in RHI - Add Pix3.h support - Cleanup SetName usage and remove it from shipping builds. - Fix fence reuse bug. We were signaling MAX UINT (-1) and then waiting for 0, which was always signaled. This change also removes the fence value reset code, there is no need to reset a fence to a previous value. - Use FPlatformAtomics::InterlockedIncrement instead of InterlockedIncrement64 - Use InterlockedIncrement() instead of _InterlockedIncrement() and use the FPlatformAtomics:: version. - Fix possible readback heap being evicted while in use. GetQueryData happens on the render thread and isn't tied to a command list so we should always have readback heaps resident. Change 3264251 on 2017/01/19 by Mark.Satterthwaite Modify some asserts in MetalRHI - technically using a store-action of ENoAction on Stencil buffers should make it invalid to restart a render-pass but on Mac it will work because ENoAction won't invalidate anything written. In future we need to use deferred store-actions in Metal so that we can "restart" passes while enforcing correct Load/Store actions. #jira UE-40803 Change 3264642 on 2017/01/19 by Daniel.Wright Raised GMaxShadowDepthBufferSizeX to max texture resolution on most platforms, was previously 4096.

Duplicate & amend CL #3266053 from Trepka: Fixed issues with shader cache not working properly with Mac Metal (but it still requires -norhithread to work at all). Enabled the shader cache by default if RHI thread is disabled. Amend & integrate RCO's CL #3197085. Change 3267741 on 2017/01/23 by Rolando.Caloca DR - Detect duplicated shader and pipeline types Change 3268600 on 2017/01/23 by Uriel.Doyon Added missing r.Streaming.MaxEffectiveScreenSize config to base texture scability settings.

The allocator allocates non-contiguous ranges of pages and maps them onto a contiguous virtual address range.

Distance Field AO is now evaluated on a screen grid and using a global distance field for far traces * Screen grid resolution is 1/8th of primary resolution, but with 4x temporal supersampling through jittering subsample positions. A longer history filter is required to hide the jittering which can increase ghosting. * The main benefit of doing cone tracing on a screen grid instead of the previous surface cache is that it's performance is generally constant regardless of camera movement or noisy geometry (foliage) * A global distance field is now used for cone traces after a certain distance, DFAO is 2-4x faster as a result. * The global distance field is composed of 4 128^3 clipmaps that follow the camera around * Clipmaps are scrolled so that only new or dirty regions are updated due to camera or object movement, with close to 0 average GPU cost. Worst case update cost (camera teleport) is 5ms on 7870. * The global distance field currently breaks Distance Field GI * Overall with these changes DFAO in a Fortnite level is 3.4ms on a 7870 (3.8ms on PS4), and 4.0ms in the Kite demo on 7870.

Add code to compute the correct number of valid rendertargets to prevent an issue during PSO creation when NumRenderTargets is >0, but none of the formats are valid (all formats are DXGI_UNKNOWN) #jira UE-40332 Change 3251141 on 2017/01/09 by Ben.Woodhouse Duplicated from Fortnite CL 3243458: D3D12 memory optimization - The d3d12 buddy suballocator is very wasteful for allocations above 4KB, but the vast majority of allocations are smaller . In the default buffer allocator this was causing 149MB of waste in 340MB of allocations. Moving the max allocation size threshold down to 4KB from 512KB saved 100MB of memory wastage memory. On PC, buffers are 64KB aligned, so we need the threshold to be higher to avoid additional wastage. Add PIX memory tracking instrumentation for buddy allocators so we can track the memory properly in PIX Change 3251142 on 2017/01/09 by Ben.Woodhouse Duplicated from Fortnite 3243496 memory optimisation: use NULL-terminated ansi strings instead of unicode FStrings for symbols, saving 118MB. Previously the strings were loaded from disk as ansi and then converted to FStrings (slowly), before finally being converted them back to ansi strings before being used. In addition to reducing memory overhead, this change reduces complexity and improves startup time. Change 3252323 on 2017/01/10 by Rolando.Caloca DR - Gfx async PSO creation prep Change 3252474 on 2017/01/10 by Daniel.Wright Added 'Compile Unreal Lightmass' to error message Change 3252589 on 2017/01/10 by Daniel.Wright Back out bulk data for distance fields from cl 3241990 which causes distance fields to be corrupt in Fortnite Change 3252790 on 2017/01/10 by Daniel.Wright Added InscatteringColorCubemapAngle to exponential height fog Change 3252843 on 2017/01/10 by Uriel.Doyon Propper fix for UE-40211, where texture streaming bound defrag and async tasks could interact in coherent ways. The bound defrag is now done outside of the async work logic. Change 3252866 on 2017/01/10 by Mark.Satterthwaite Fix Metal shader pipeline hash collisions caused by deferring MTLFunction construction until PrepareToDraw so that we may use Function-Constants to specialise the shader source without generating additional permutations. This is required to generate proper tessellation shaders which are specialised against the index-buffer usage & type (none, uint16, uint32). While we're here amend the hash functions to make better use of the existing hash functions to improve the distribution and hopefully reduce the possibility of collisions in future. #jira UE-40357 Change 3254511 on 2017/01/11 by Rolando.Caloca DR - PSO stats Change 3255958 on 2017/01/12 by Mark.Satterthwaite Reimplement RQT_AbsoluteTime for Metal - pretty sure I did this before, but somehow it got lost. When a RQT_AbsoluteTime is inserted into the command-stream, insert a command-buffer completion handler to record the time of completion & submit the command-buffer immediately. This breaks command-buffers so is noticeably slower and if inserted in a pass that can't be restarted will fail but is currently the only option available. This is sufficient to support the GPUBenchmark used by Scalability. To make this more efficient I've refactored the FMetalCommandBufferFence implementation so that we use a single shared-ptr object containing the command-buffer and a dispatch semaphore, rather than allocating one for each query. The semaphore allows for timed-waits where previously we'd block until completion, unlike the other APIs that report failure after a fixed interval (2s for RQT_AbsoluteTime, otherwise 0.5s). Sadly not all drivers support this abuse of the Metal API, so replace the GL-based workaround for not having time queries with one that just guesses based on RHI device details. Radars will be filed. #jira UE-40554 Change 3256329 on 2017/01/12 by Olaf.Piesche #jira UE-38615 Assert shouldn't be necessary; in fact, it causes a crash when exporting emitters, since in that case we're changing the template at runtime.

OutEnvironment.SetDefine(TEXT("SUPPORT_IRRADIANCE"), bSupportIrradiance);
Distance Field AO is now evaluated on a screen grid and using a global distance field for far traces * Screen grid resolution is 1/8th of primary resolution, but with 4x temporal supersampling through jittering subsample positions. A longer history filter is required to hide the jittering which can increase ghosting. * The main benefit of doing cone tracing on a screen grid instead of the previous surface cache is that it's performance is generally constant regardless of camera movement or noisy geometry (foliage) * A global distance field is now used for cone traces after a certain distance, DFAO is 2-4x faster as a result. * The global distance field is composed of 4 128^3 clipmaps that follow the camera around * Clipmaps are scrolled so that only new or dirty regions are updated due to camera or object movement, with close to 0 average GPU cost. Worst case update cost (camera teleport) is 5ms on 7870. * The global distance field currently breaks Distance Field GI * Overall with these changes DFAO in a Fortnite level is 3.4ms on a 7870 (3.8ms on PS4), and 4.0ms in the Kite demo on 7870.

Add code to compute the correct number of valid rendertargets to prevent an issue during PSO creation when NumRenderTargets is >0, but none of the formats are valid (all formats are DXGI_UNKNOWN) #jira UE-40332 Change 3251141 on 2017/01/09 by Ben.Woodhouse Duplicated from Fortnite CL 3243458: D3D12 memory optimization - The d3d12 buddy suballocator is very wasteful for allocations above 4KB, but the vast majority of allocations are smaller . In the default buffer allocator this was causing 149MB of waste in 340MB of allocations. Moving the max allocation size threshold down to 4KB from 512KB saved 100MB of memory wastage memory. On PC, buffers are 64KB aligned, so we need the threshold to be higher to avoid additional wastage. Add PIX memory tracking instrumentation for buddy allocators so we can track the memory properly in PIX Change 3251142 on 2017/01/09 by Ben.Woodhouse Duplicated from Fortnite 3243496 memory optimisation: use NULL-terminated ansi strings instead of unicode FStrings for symbols, saving 118MB. Previously the strings were loaded from disk as ansi and then converted to FStrings (slowly), before finally being converted them back to ansi strings before being used. In addition to reducing memory overhead, this change reduces complexity and improves startup time.

The bound defrag is now done outside of the async work logic. Change 3252866 on 2017/01/10 by Mark.Satterthwaite Fix Metal shader pipeline hash collisions caused by deferring MTLFunction construction until PrepareToDraw so that we may use Function-Constants to specialise the shader source without generating additional permutations. This is required to generate proper tessellation shaders which are specialised against the index-buffer usage & type (none, uint16, uint32). While we're here amend the hash functions to make better use of the existing hash functions to improve the distribution and hopefully reduce the possibility of collisions in future. #jira UE-40357 Change 3254511 on 2017/01/11 by Rolando.Caloca DR - PSO stats Change 3255958 on 2017/01/12 by Mark.Satterthwaite Reimplement RQT_AbsoluteTime for Metal - pretty sure I did this before, but somehow it got lost. When a RQT_AbsoluteTime is inserted into the command-stream, insert a command-buffer completion handler to record the time of completion & submit the command-buffer immediately. This breaks command-buffers so is noticeably slower and if inserted in a pass that can't be restarted will fail but is currently the only option available. This is sufficient to support the GPUBenchmark used by Scalability. To make this more efficient I've refactored the FMetalCommandBufferFence implementation so that we use a single shared-ptr object containing the command-buffer and a dispatch semaphore, rather than allocating one for each query. The semaphore allows for timed-waits where previously we'd block until completion, unlike the other APIs that report failure after a fixed interval (2s for RQT_AbsoluteTime, otherwise 0.5s). Sadly not all drivers support this abuse of the Metal API, so replace the GL-based workaround for not having time queries with one that just guesses based on RHI device details. Radars will be filed. #jira UE-40554 Change 3256329 on 2017/01/12 by Olaf.Piesche #jira UE-38615 Assert shouldn't be necessary; in fact, it causes a crash when exporting emitters, since in that case we're changing the template at runtime.

Deprecated IsRunning() in favour of a new Update() method because polling IsRunning is not compatible with -nothreading mode #jira UE-40841 Change 3264153 on 2017/01/19 by Ben.Woodhouse Integrate latest changes from MS-DX12 CLs 3231395-3262526 - Added WinPixEventRuntime.tps - Includes PIX support, various optimizations (saved 1.3ms in testbed scene) CL 3262343: Fix depth testing on translucency not working correctly after cl 3231395. This change reapplies the D3D12RHI changes from CL 3231395 because those changes were lost when integrating from //Dev-Rendering/ but also includes the depth fixes: - Fix depth state not being in DEPTH_READ for use as depth read. The issue was HasDepthBits and HasStencilBits wern't intended for SRV formats and always returned false in the SRV case. CL 3231395: Update D3D12 RHI: - Fix deferred MSAA path in RHI - Add Pix3.h support - Cleanup SetName usage and remove it from shipping builds. - Fix fence reuse bug. We were signaling MAX UINT (-1) and then waiting for 0, which was always signaled. This change also removes the fence value reset code, there is no need to reset a fence to a previous value. - Use FPlatformAtomics::InterlockedIncrement instead of InterlockedIncrement64 - Use InterlockedIncrement() instead of _InterlockedIncrement() and use the FPlatformAtomics:: version. - Fix possible readback heap being evicted while in use. GetQueryData happens on the render thread and isn't tied to a command list so we should always have readback heaps resident. Change 3264251 on 2017/01/19 by Mark.Satterthwaite Modify some asserts in MetalRHI - technically using a store-action of ENoAction on Stencil buffers should make it invalid to restart a render-pass but on Mac it will work because ENoAction won't invalidate anything written. In future we need to use deferred store-actions in Metal so that we can "restart" passes while enforcing correct Load/Store actions. #jira UE-40803 Change 3264642 on 2017/01/19 by Daniel.Wright Raised GMaxShadowDepthBufferSizeX to max texture resolution on most platforms, was previously 4096.

Duplicate & amend CL #3266053 from Trepka: Fixed issues with shader cache not working properly with Mac Metal (but it still requires -norhithread to work at all). Enabled the shader cache by default if RHI thread is disabled. Amend & integrate RCO's CL #3197085. Change 3267741 on 2017/01/23 by Rolando.Caloca DR - Detect duplicated shader and pipeline types Change 3268600 on 2017/01/23 by Uriel.Doyon Added missing r.Streaming.MaxEffectiveScreenSize config to base texture scability settings. Integrated CL 3227368 from Orion stream Enabled r.Streaming.UsePerTextureBias by default as this has been tested in Orion for several months. Fixed issue with the InvestigateTexture command which could return invalid reference depending on the timing, Added th MaxEffectiveScreenSize settings in the investigate texture command. Change 3269512 on 2017/01/24 by Richard.Wallis Fix for shader binary cache uncompress data size during internal shader log. Change 3271237 on 2017/01/25 by Ben.Woodhouse D3D12 updateTexture2D crash fix #jira UE-41059 Change 3271564 on 2017/01/25 by Olaf.Piesche #jira UE-40980 #udn 325525 Fix uniform buffers for mesh particles; these should really be on the mesh collector, so allocating them as a one frame resource is safe Change 3271594 on 2017/01/25 by Ben.Woodhouse ESRAM support stage 1: Implemented noncontiguous ESRAM page allocator replacing XgMemoryLayout API. The allocator allocates non-contiguous ranges of pages and maps them onto a contiguous virtual address range. Unlike the previous implementation, this allocator frees pages for reuse when resources are destroyed Note: issues with deferred deallocation may prevent reuse in many cases - that will be addressed in the next stage Support for the old allocator is still available (for now) via the define NEW_ESRAM_ALLOCATOR #fyi rolando.caloca Change 3272616 on 2017/01/25 by Rolando.Caloca DR - Update shader version Change 3273138 on 2017/01/26 by Ben.Woodhouse Fix merge issue with MonitoredProcess.cpp (this arose from an integration made as an edit in dev-rendering, which confused perforce when the change was subsequently integrated from main) [CL 3274498 by Rolando Caloca in Main branch]

Distance Field AO is now evaluated on a screen grid and using a global distance field for far traces * Screen grid resolution is 1/8th of primary resolution, but with 4x temporal supersampling through jittering subsample positions. A longer history filter is required to hide the jittering which can increase ghosting. * The main benefit of doing cone tracing on a screen grid instead of the previous surface cache is that it's performance is generally constant regardless of camera movement or noisy geometry (foliage) * A global distance field is now used for cone traces after a certain distance, DFAO is 2-4x faster as a result. * The global distance field is composed of 4 128^3 clipmaps that follow the camera around * Clipmaps are scrolled so that only new or dirty regions are updated due to camera or object movement, with close to 0 average GPU cost. Worst case update cost (camera teleport) is 5ms on 7870. * The global distance field currently breaks Distance Field GI * Overall with these changes DFAO in a Fortnite level is 3.4ms on a 7870 (3.8ms on PS4), and 4.0ms in the Kite demo on 7870.

Distance Field AO is now evaluated on a screen grid and using a global distance field for far traces * Screen grid resolution is 1/8th of primary resolution, but with 4x temporal supersampling through jittering subsample positions. A longer history filter is required to hide the jittering which can increase ghosting. * The main benefit of doing cone tracing on a screen grid instead of the previous surface cache is that it's performance is generally constant regardless of camera movement or noisy geometry (foliage) * A global distance field is now used for cone traces after a certain distance, DFAO is 2-4x faster as a result. * The global distance field is composed of 4 128^3 clipmaps that follow the camera around * Clipmaps are scrolled so that only new or dirty regions are updated due to camera or object movement, with close to 0 average GPU cost. Worst case update cost (camera teleport) is 5ms on 7870. * The global distance field currently breaks Distance Field GI * Overall with these changes DFAO in a Fortnite level is 3.4ms on a 7870 (3.8ms on PS4), and 4.0ms in the Kite demo on 7870.

Distance Field AO is now evaluated on a screen grid and using a global distance field for far traces * Screen grid resolution is 1/8th of primary resolution, but with 4x temporal supersampling through jittering subsample positions. A longer history filter is required to hide the jittering which can increase ghosting. * The main benefit of doing cone tracing on a screen grid instead of the previous surface cache is that it's performance is generally constant regardless of camera movement or noisy geometry (foliage) * A global distance field is now used for cone traces after a certain distance, DFAO is 2-4x faster as a result. * The global distance field is composed of 4 128^3 clipmaps that follow the camera around * Clipmaps are scrolled so that only new or dirty regions are updated due to camera or object movement, with close to 0 average GPU cost. Worst case update cost (camera teleport) is 5ms on 7870. * The global distance field currently breaks Distance Field GI * Overall with these changes DFAO in a Fortnite level is 3.4ms on a 7870 (3.8ms on PS4), and 4.0ms in the Kite demo on 7870.

Distance Field AO is now evaluated on a screen grid and using a global distance field for far traces * Screen grid resolution is 1/8th of primary resolution, but with 4x temporal supersampling through jittering subsample positions. A longer history filter is required to hide the jittering which can increase ghosting. * The main benefit of doing cone tracing on a screen grid instead of the previous surface cache is that it's performance is generally constant regardless of camera movement or noisy geometry (foliage) * A global distance field is now used for cone traces after a certain distance, DFAO is 2-4x faster as a result. * The global distance field is composed of 4 128^3 clipmaps that follow the camera around * Clipmaps are scrolled so that only new or dirty regions are updated due to camera or object movement, with close to 0 average GPU cost. Worst case update cost (camera teleport) is 5ms on 7870. * The global distance field currently breaks Distance Field GI * Overall with these changes DFAO in a Fortnite level is 3.4ms on a 7870 (3.8ms on PS4), and 4.0ms in the Kite demo on 7870.

Distance Field AO is now evaluated on a screen grid and using a global distance field for far traces * Screen grid resolution is 1/8th of primary resolution, but with 4x temporal supersampling through jittering subsample positions. A longer history filter is required to hide the jittering which can increase ghosting. * The main benefit of doing cone tracing on a screen grid instead of the previous surface cache is that it's performance is generally constant regardless of camera movement or noisy geometry (foliage) * A global distance field is now used for cone traces after a certain distance, DFAO is 2-4x faster as a result. * The global distance field is composed of 4 128^3 clipmaps that follow the camera around * Clipmaps are scrolled so that only new or dirty regions are updated due to camera or object movement, with close to 0 average GPU cost. Worst case update cost (camera teleport) is 5ms on 7870. * The global distance field currently breaks Distance Field GI * Overall with these changes DFAO in a Fortnite level is 3.4ms on a 7870 (3.8ms on PS4), and 4.0ms in the Kite demo on 7870.

Distance Field AO is now evaluated on a screen grid and using a global distance field for far traces * Screen grid resolution is 1/8th of primary resolution, but with 4x temporal supersampling through jittering subsample positions. A longer history filter is required to hide the jittering which can increase ghosting. * The main benefit of doing cone tracing on a screen grid instead of the previous surface cache is that it's performance is generally constant regardless of camera movement or noisy geometry (foliage) * A global distance field is now used for cone traces after a certain distance, DFAO is 2-4x faster as a result. * The global distance field is composed of 4 128^3 clipmaps that follow the camera around * Clipmaps are scrolled so that only new or dirty regions are updated due to camera or object movement, with close to 0 average GPU cost. Worst case update cost (camera teleport) is 5ms on 7870. * The global distance field currently breaks Distance Field GI * Overall with these changes DFAO in a Fortnite level is 3.4ms on a 7870 (3.8ms on PS4), and 4.0ms in the Kite demo on 7870.

Distance Field AO is now evaluated on a screen grid and using a global distance field for far traces * Screen grid resolution is 1/8th of primary resolution, but with 4x temporal supersampling through jittering subsample positions. A longer history filter is required to hide the jittering which can increase ghosting. * The main benefit of doing cone tracing on a screen grid instead of the previous surface cache is that it's performance is generally constant regardless of camera movement or noisy geometry (foliage) * A global distance field is now used for cone traces after a certain distance, DFAO is 2-4x faster as a result. * The global distance field is composed of 4 128^3 clipmaps that follow the camera around * Clipmaps are scrolled so that only new or dirty regions are updated due to camera or object movement, with close to 0 average GPU cost. Worst case update cost (camera teleport) is 5ms on 7870. * The global distance field currently breaks Distance Field GI * Overall with these changes DFAO in a Fortnite level is 3.4ms on a 7870 (3.8ms on PS4), and 4.0ms in the Kite demo on 7870.

Change 3333790 on 2017/03/06 by Daniel.Wright [Copy] Mesh distance field generation uses Embree, for a 2.5x speedup * Can switch back to old kDOP generation with 'r.DistanceFieldBuild.UseEmbree 0' for debugging Change 3333822 on 2017/03/06 by Daniel.Wright [Copy] Moved mesh distance field code into MeshDistanceFieldUtilities.cpp * Moved FMeshUtilities to its own header so the 8k line MeshUtilites.cpp file can be further split up Change 3333827 on 2017/03/06 by Daniel.Wright [Copy] Range compress 8bit distance fields - gets one extra bit of precision on average Change 3333828 on 2017/03/06 by Daniel.Wright [Copy] Raised High ShadowQuality to 2048 as 1024 for CSM is way too low Change 3333831 on 2017/03/06 by Daniel.Wright Non-editor compile fix Change 3333836 on 2017/03/06 by Daniel.Wright [Copy] Workaround for gobal distance field volume textures being bloated by 4x on PS4 due to the recommended tiling modes. They now use a 2d tiling mode which avoids the bloat, saving 96Mb. Change 3333843 on 2017/03/06 by Daniel.Wright [Copy] Added OcclusionExponent to skylight component * Useful for brightening up indoors without losing contact shadows as MinOcclusion does Change 3333845 on 2017/03/06 by Daniel.Wright [Copy] Capsule shadow BP functions Change 3333850 on 2017/03/06 by Daniel.Wright [Copy] Added OcclusionCombineMode to skylight component Change 3333854 on 2017/03/06 by Daniel.Wright [Copy] Gnm properly registers clears as GPU work so those events show up in profilegpu Change 3333857 on 2017/03/06 by Daniel.Wright [Copy] Clear light attenuation for local lights with a quad covering their screen extents * Clearing the entire light attenuation buffer costs .1ms on PS4.

All properties are in world space densities. * Particle systems using the Volume domain are voxelized based on their ParticlePosition and ParticleRadius * Volumetric fog integration is now energy conservative - scattering is integrated against transmission over the depth of each slice. * Added bOverrideLightColorsWithFogInscatteringColors to exponential height fog, which can be enabled to make Volumetric Fog match Height fog more closely Change 3334134 on 2017/03/06 by Daniel.Wright [Copy from Michael Trepka] Added Embree 2.14.0 and changed MeshUtilities to use it as this solves issues with Embree leaking TLS keys. UnrealLightmass is still using older Embree 2.7.0 until we can find time to properly test it with the new version. Also, invalidated distance field DDC to force it to rebuild with updated Embree.

Distance Field AO is now evaluated on a screen grid and using a global distance field for far traces * Screen grid resolution is 1/8th of primary resolution, but with 4x temporal supersampling through jittering subsample positions. A longer history filter is required to hide the jittering which can increase ghosting. * The main benefit of doing cone tracing on a screen grid instead of the previous surface cache is that it's performance is generally constant regardless of camera movement or noisy geometry (foliage) * A global distance field is now used for cone traces after a certain distance, DFAO is 2-4x faster as a result. * The global distance field is composed of 4 128^3 clipmaps that follow the camera around * Clipmaps are scrolled so that only new or dirty regions are updated due to camera or object movement, with close to 0 average GPU cost.

In the default buffer allocator this was causing 149MB of waste in 340MB of allocations. Moving the max allocation size threshold down to 4KB from 512KB saved 100MB of memory wastage memory.

Change 3252323 on 2017/01/10 by Rolando.Caloca DR - Gfx async PSO creation prep Change 3252474 on 2017/01/10 by Daniel.Wright Added 'Compile Unreal Lightmass' to error message Change 3252589 on 2017/01/10 by Daniel.Wright Back out bulk data for distance fields from cl 3241990 which causes distance fields to be corrupt in Fortnite Change 3252790 on 2017/01/10 by Daniel.Wright Added InscatteringColorCubemapAngle to exponential height fog Change 3252843 on 2017/01/10 by Uriel.Doyon Propper fix for UE-40211, where texture streaming bound defrag and async tasks could interact in coherent ways. The bound defrag is now done outside of the async work logic. Change 3252866 on 2017/01/10 by Mark.Satterthwaite Fix Metal shader pipeline hash collisions caused by deferring MTLFunction construction until PrepareToDraw so that we may use Function-Constants to specialise the shader source without generating additional permutations. This is required to generate proper tessellation shaders which are specialised against the index-buffer usage & type (none, uint16, uint32). While we're here amend the hash functions to make better use of the existing hash functions to improve the distribution and hopefully reduce the possibility of collisions in future. #jira UE-40357 Change 3254511 on 2017/01/11 by Rolando.Caloca DR - PSO stats Change 3255958 on 2017/01/12 by Mark.Satterthwaite Reimplement RQT_AbsoluteTime for Metal - pretty sure I did this before, but somehow it got lost. When a RQT_AbsoluteTime is inserted into the command-stream, insert a command-buffer completion handler to record the time of completion & submit the command-buffer immediately. This breaks command-buffers so is noticeably slower and if inserted in a pass that can't be restarted will fail but is currently the only option available. This is sufficient to support the GPUBenchmark used by Scalability. To make this more efficient I've refactored the FMetalCommandBufferFence implementation so that we use a single shared-ptr object containing the command-buffer and a dispatch semaphore, rather than allocating one for each query. The semaphore allows for timed-waits where previously we'd block until completion, unlike the other APIs that report failure after a fixed interval (2s for RQT_AbsoluteTime, otherwise 0.5s). Sadly not all drivers support this abuse of the Metal API, so replace the GL-based workaround for not having time queries with one that just guesses based on RHI device details. Radars will be filed. #jira UE-40554 Change 3256329 on 2017/01/12 by Olaf.Piesche #jira UE-38615 Assert shouldn't be necessary; in fact, it causes a crash when exporting emitters, since in that case we're changing the template at runtime.

Worst case full volume update is mostly the same. * Adds 12Mb for the new volume textures Change 3260956 on 2017/01/17 by Daniel.Wright Structured buffers for DF object data * Full global distance field clipmap composite 3.0ms -> 2.0ms due to scalarized loads Change 3261296 on 2017/01/17 by Daniel.Wright Exposed MaxObjectsPerTile with 'r.AOMaxObjectsPerCullTile' and lowered the default from 512 to 256, saves 17Mb of object tile culling data structures Removed unnecessary UAV transitions preventing object and global cone tracing from overlapping, saves ~.1ms Change 3262036 on 2017/01/18 by Ben.Salem V0 of Perf monitor plugin for easily consumable stat csvs. With plugin enabled, enter PerformanceMonitor help into the console to get usage details.

This change reapplies the D3D12RHI changes from CL 3231395 because those changes were lost when integrating from //Dev-Rendering/ but also includes the depth fixes: - Fix depth state not being in DEPTH_READ for use as depth read. The issue was HasDepthBits and HasStencilBits wern't intended for SRV formats and always returned false in the SRV case. CL 3231395: Update D3D12 RHI: - Fix deferred MSAA path in RHI - Add Pix3.h support - Cleanup SetName usage and remove it from shipping builds. - Fix fence reuse bug. We were signaling MAX UINT (-1) and then waiting for 0, which was always signaled. This change also removes the fence value reset code, there is no need to reset a fence to a previous value. - Use FPlatformAtomics::InterlockedIncrement instead of InterlockedIncrement64 - Use InterlockedIncrement() instead of _InterlockedIncrement() and use the FPlatformAtomics:: version. - Fix possible readback heap being evicted while in use. GetQueryData happens on the render thread and isn't tied to a command list so we should always have readback heaps resident. Change 3264251 on 2017/01/19 by Mark.Satterthwaite Modify some asserts in MetalRHI - technically using a store-action of ENoAction on Stencil buffers should make it invalid to restart a render-pass but on Mac it will work because ENoAction won't invalidate anything written. In future we need to use deferred store-actions in Metal so that we can "restart" passes while enforcing correct Load/Store actions. #jira UE-40803 Change 3264642 on 2017/01/19 by Daniel.Wright Raised GMaxShadowDepthBufferSizeX to max texture resolution on most platforms, was previously 4096.

In the default buffer allocator this was causing 149MB of waste in 340MB of allocations. Moving the max allocation size threshold down to 4KB from 512KB saved 100MB of memory wastage memory. On PC, buffers are 64KB aligned, so we need the threshold to be higher to avoid additional wastage. Add PIX memory tracking instrumentation for buddy allocators so we can track the memory properly in PIX Change 3251142 on 2017/01/09 by Ben.Woodhouse Duplicated from Fortnite 3243496 memory optimisation: use NULL-terminated ansi strings instead of unicode FStrings for symbols, saving 118MB. Previously the strings were loaded from disk as ansi and then converted to FStrings (slowly), before finally being converted them back to ansi strings before being used.

The bound defrag is now done outside of the async work logic. Change 3252866 on 2017/01/10 by Mark.Satterthwaite Fix Metal shader pipeline hash collisions caused by deferring MTLFunction construction until PrepareToDraw so that we may use Function-Constants to specialise the shader source without generating additional permutations. This is required to generate proper tessellation shaders which are specialised against the index-buffer usage & type (none, uint16, uint32). While we're here amend the hash functions to make better use of the existing hash functions to improve the distribution and hopefully reduce the possibility of collisions in future. #jira UE-40357 Change 3254511 on 2017/01/11 by Rolando.Caloca DR - PSO stats Change 3255958 on 2017/01/12 by Mark.Satterthwaite Reimplement RQT_AbsoluteTime for Metal - pretty sure I did this before, but somehow it got lost. When a RQT_AbsoluteTime is inserted into the command-stream, insert a command-buffer completion handler to record the time of completion & submit the command-buffer immediately. This breaks command-buffers so is noticeably slower and if inserted in a pass that can't be restarted will fail but is currently the only option available. This is sufficient to support the GPUBenchmark used by Scalability. To make this more efficient I've refactored the FMetalCommandBufferFence implementation so that we use a single shared-ptr object containing the command-buffer and a dispatch semaphore, rather than allocating one for each query. The semaphore allows for timed-waits where previously we'd block until completion, unlike the other APIs that report failure after a fixed interval (2s for RQT_AbsoluteTime, otherwise 0.5s). Sadly not all drivers support this abuse of the Metal API, so replace the GL-based workaround for not having time queries with one that just guesses based on RHI device details. Radars will be filed. #jira UE-40554 Change 3256329 on 2017/01/12 by Olaf.Piesche #jira UE-38615 Assert shouldn't be necessary; in fact, it causes a crash when exporting emitters, since in that case we're changing the template at runtime.

CL 3231395: Update D3D12 RHI: - Fix deferred MSAA path in RHI - Add Pix3.h support - Cleanup SetName usage and remove it from shipping builds. - Fix fence reuse bug. We were signaling MAX UINT (-1) and then waiting for 0, which was always signaled. This change also removes the fence value reset code, there is no need to reset a fence to a previous value. - Use FPlatformAtomics::InterlockedIncrement instead of InterlockedIncrement64 - Use InterlockedIncrement() instead of _InterlockedIncrement() and use the FPlatformAtomics:: version. - Fix possible readback heap being evicted while in use. GetQueryData happens on the render thread and isn't tied to a command list so we should always have readback heaps resident.

Added an incremental update in the last stage of the texture streaming update load to clear any pending work. Added an option "All" to the "BuildMateriaTexturelStreamingData" command to force rebuild everything. Change 3235317 on 2016/12/14 by Uriel.Doyon Removed timed primitives in the texture streaming since it was not used and there is now a fallback implementation in UPrimitiveComponent::GetStreamingTextureInfo.

Refactored the code to separate the concept or valid render-states in the cache from active render-states in the render-pass. Now it works as intended and will be needed for 4.15.

Long-term the Metal tessellation code will need to be refactored so that the vertex shader stage is emitted as a separate shader from the hull shader stage as this but will keep cropping back up and continue to complicate the engine. #jira UE-39799 Change 3237490 on 2016/12/15 by Daniel.Wright Fixed ULandscapeComponent::GetUsedMaterials Change 3237597 on 2016/12/15 by Ben.Woodhouse Disable timestamp queries on pre-Maxwell nvidia hardware. Local testing suggests that this is the major cause of instability in the UE4.14 release. It's possible that we could be more targeted by only excluding Fermi and older hardware, but identifying fermi hardware by device ID is difficult in practice, since the range overlaps with Kepler.

Distance Field AO is now evaluated on a screen grid and using a global distance field for far traces * Screen grid resolution is 1/8th of primary resolution, but with 4x temporal supersampling through jittering subsample positions. A longer history filter is required to hide the jittering which can increase ghosting. * The main benefit of doing cone tracing on a screen grid instead of the previous surface cache is that it's performance is generally constant regardless of camera movement or noisy geometry (foliage) * A global distance field is now used for cone traces after a certain distance, DFAO is 2-4x faster as a result. * The global distance field is composed of 4 128^3 clipmaps that follow the camera around * Clipmaps are scrolled so that only new or dirty regions are updated due to camera or object movement, with close to 0 average GPU cost. Worst case update cost (camera teleport) is 5ms on 7870. * The global distance field currently breaks Distance Field GI * Overall with these changes DFAO in a Fortnite level is 3.4ms on a 7870 (3.8ms on PS4), and 4.0ms in the Kite demo on 7870.

Add code to compute the correct number of valid rendertargets to prevent an issue during PSO creation when NumRenderTargets is >0, but none of the formats are valid (all formats are DXGI_UNKNOWN) #jira UE-40332 Change 3251141 on 2017/01/09 by Ben.Woodhouse Duplicated from Fortnite CL 3243458: D3D12 memory optimization - The d3d12 buddy suballocator is very wasteful for allocations above 4KB, but the vast majority of allocations are smaller . In the default buffer allocator this was causing 149MB of waste in 340MB of allocations. Moving the max allocation size threshold down to 4KB from 512KB saved 100MB of memory wastage memory. On PC, buffers are 64KB aligned, so we need the threshold to be higher to avoid additional wastage. Add PIX memory tracking instrumentation for buddy allocators so we can track the memory properly in PIX Change 3251142 on 2017/01/09 by Ben.Woodhouse Duplicated from Fortnite 3243496 memory optimisation: use NULL-terminated ansi strings instead of unicode FStrings for symbols, saving 118MB. Previously the strings were loaded from disk as ansi and then converted to FStrings (slowly), before finally being converted them back to ansi strings before being used. In addition to reducing memory overhead, this change reduces complexity and improves startup time. Change 3252323 on 2017/01/10 by Rolando.Caloca DR - Gfx async PSO creation prep Change 3252474 on 2017/01/10 by Daniel.Wright Added 'Compile Unreal Lightmass' to error message Change 3252589 on 2017/01/10 by Daniel.Wright Back out bulk data for distance fields from cl 3241990 which causes distance fields to be corrupt in Fortnite Change 3252790 on 2017/01/10 by Daniel.Wright Added InscatteringColorCubemapAngle to exponential height fog Change 3252843 on 2017/01/10 by Uriel.Doyon Propper fix for UE-40211, where texture streaming bound defrag and async tasks could interact in coherent ways. The bound defrag is now done outside of the async work logic. Change 3252866 on 2017/01/10 by Mark.Satterthwaite Fix Metal shader pipeline hash collisions caused by deferring MTLFunction construction until PrepareToDraw so that we may use Function-Constants to specialise the shader source without generating additional permutations. This is required to generate proper tessellation shaders which are specialised against the index-buffer usage & type (none, uint16, uint32). While we're here amend the hash functions to make better use of the existing hash functions to improve the distribution and hopefully reduce the possibility of collisions in future. #jira UE-40357 Change 3254511 on 2017/01/11 by Rolando.Caloca DR - PSO stats Change 3255958 on 2017/01/12 by Mark.Satterthwaite Reimplement RQT_AbsoluteTime for Metal - pretty sure I did this before, but somehow it got lost. When a RQT_AbsoluteTime is inserted into the command-stream, insert a command-buffer completion handler to record the time of completion & submit the command-buffer immediately. This breaks command-buffers so is noticeably slower and if inserted in a pass that can't be restarted will fail but is currently the only option available. This is sufficient to support the GPUBenchmark used by Scalability. To make this more efficient I've refactored the FMetalCommandBufferFence implementation so that we use a single shared-ptr object containing the command-buffer and a dispatch semaphore, rather than allocating one for each query. The semaphore allows for timed-waits where previously we'd block until completion, unlike the other APIs that report failure after a fixed interval (2s for RQT_AbsoluteTime, otherwise 0.5s). Sadly not all drivers support this abuse of the Metal API, so replace the GL-based workaround for not having time queries with one that just guesses based on RHI device details.

This change reapplies the D3D12RHI changes from CL 3231395 because those changes were lost when integrating from //Dev-Rendering/ but also includes the depth fixes: - Fix depth state not being in DEPTH_READ for use as depth read. The issue was HasDepthBits and HasStencilBits wern't intended for SRV formats and always returned false in the SRV case. CL 3231395: Update D3D12 RHI: - Fix deferred MSAA path in RHI - Add Pix3.h support - Cleanup SetName usage and remove it from shipping builds. - Fix fence reuse bug. We were signaling MAX UINT (-1) and then waiting for 0, which was always signaled. This change also removes the fence value reset code, there is no need to reset a fence to a previous value. - Use FPlatformAtomics::InterlockedIncrement instead of InterlockedIncrement64 - Use InterlockedIncrement() instead of _InterlockedIncrement() and use the FPlatformAtomics:: version. - Fix possible readback heap being evicted while in use. GetQueryData happens on the render thread and isn't tied to a command list so we should always have readback heaps resident. Change 3264251 on 2017/01/19 by Mark.Satterthwaite Modify some asserts in MetalRHI - technically using a store-action of ENoAction on Stencil buffers should make it invalid to restart a render-pass but on Mac it will work because ENoAction won't invalidate anything written.

The allocator allocates non-contiguous ranges of pages and maps them onto a contiguous virtual address range.

Add code to compute the correct number of valid rendertargets to prevent an issue during PSO creation when NumRenderTargets is >0, but none of the formats are valid (all formats are DXGI_UNKNOWN) #jira UE-40332 Change 3251141 on 2017/01/09 by Ben.Woodhouse Duplicated from Fortnite CL 3243458: D3D12 memory optimization - The d3d12 buddy suballocator is very wasteful for allocations above 4KB, but the vast majority of allocations are smaller . In the default buffer allocator this was causing 149MB of waste in 340MB of allocations. Moving the max allocation size threshold down to 4KB from 512KB saved 100MB of memory wastage memory. On PC, buffers are 64KB aligned, so we need the threshold to be higher to avoid additional wastage. Add PIX memory tracking instrumentation for buddy allocators so we can track the memory properly in PIX Change 3251142 on 2017/01/09 by Ben.Woodhouse Duplicated from Fortnite 3243496 memory optimisation: use NULL-terminated ansi strings instead of unicode FStrings for symbols, saving 118MB. Previously the strings were loaded from disk as ansi and then converted to FStrings (slowly), before finally being converted them back to ansi strings before being used. In addition to reducing memory overhead, this change reduces complexity and improves startup time. Change 3252323 on 2017/01/10 by Rolando.Caloca DR - Gfx async PSO creation prep Change 3252474 on 2017/01/10 by Daniel.Wright Added 'Compile Unreal Lightmass' to error message Change 3252589 on 2017/01/10 by Daniel.Wright Back out bulk data for distance fields from cl 3241990 which causes distance fields to be corrupt in Fortnite Change 3252790 on 2017/01/10 by Daniel.Wright Added InscatteringColorCubemapAngle to exponential height fog Change 3252843 on 2017/01/10 by Uriel.Doyon Propper fix for UE-40211, where texture streaming bound defrag and async tasks could interact in coherent ways. The bound defrag is now done outside of the async work logic. Change 3252866 on 2017/01/10 by Mark.Satterthwaite Fix Metal shader pipeline hash collisions caused by deferring MTLFunction construction until PrepareToDraw so that we may use Function-Constants to specialise the shader source without generating additional permutations. This is required to generate proper tessellation shaders which are specialised against the index-buffer usage & type (none, uint16, uint32). While we're here amend the hash functions to make better use of the existing hash functions to improve the distribution and hopefully reduce the possibility of collisions in future. #jira UE-40357 Change 3254511 on 2017/01/11 by Rolando.Caloca DR - PSO stats Change 3255958 on 2017/01/12 by Mark.Satterthwaite Reimplement RQT_AbsoluteTime for Metal - pretty sure I did this before, but somehow it got lost. When a RQT_AbsoluteTime is inserted into the command-stream, insert a command-buffer completion handler to record the time of completion & submit the command-buffer immediately. This breaks command-buffers so is noticeably slower and if inserted in a pass that can't be restarted will fail but is currently the only option available. This is sufficient to support the GPUBenchmark used by Scalability. To make this more efficient I've refactored the FMetalCommandBufferFence implementation so that we use a single shared-ptr object containing the command-buffer and a dispatch semaphore, rather than allocating one for each query. The semaphore allows for timed-waits where previously we'd block until completion, unlike the other APIs that report failure after a fixed interval (2s for RQT_AbsoluteTime, otherwise 0.5s). Sadly not all drivers support this abuse of the Metal API, so replace the GL-based workaround for not having time queries with one that just guesses based on RHI device details.

This change reapplies the D3D12RHI changes from CL 3231395 because those changes were lost when integrating from //Dev-Rendering/ but also includes the depth fixes: - Fix depth state not being in DEPTH_READ for use as depth read. The issue was HasDepthBits and HasStencilBits wern't intended for SRV formats and always returned false in the SRV case. CL 3231395: Update D3D12 RHI: - Fix deferred MSAA path in RHI - Add Pix3.h support - Cleanup SetName usage and remove it from shipping builds. - Fix fence reuse bug. We were signaling MAX UINT (-1) and then waiting for 0, which was always signaled. This change also removes the fence value reset code, there is no need to reset a fence to a previous value. - Use FPlatformAtomics::InterlockedIncrement instead of InterlockedIncrement64 - Use InterlockedIncrement() instead of _InterlockedIncrement() and use the FPlatformAtomics:: version. - Fix possible readback heap being evicted while in use. GetQueryData happens on the render thread and isn't tied to a command list so we should always have readback heaps resident. Change 3264251 on 2017/01/19 by Mark.Satterthwaite Modify some asserts in MetalRHI - technically using a store-action of ENoAction on Stencil buffers should make it invalid to restart a render-pass but on Mac it will work because ENoAction won't invalidate anything written. In future we need to use deferred store-actions in Metal so that we can "restart" passes while enforcing correct Load/Store actions. #jira UE-40803 Change 3264642 on 2017/01/19 by Daniel.Wright Raised GMaxShadowDepthBufferSizeX to max texture resolution on most platforms, was previously 4096. Change 3265330 on 2017/01/20 by Ben.Salem Stop performance plugin from building in Win32. #tests recompiled and preflighted Change 3265678 on 2017/01/20 by Marcus.Wassmer Fix bad declaration. #3055 Change 3266656 on 2017/01/20 by Mark.Satterthwaite Changes to the FShaderCache to restore it and extend it to optionally report on shader de-duplication when generating a binary shader cache (Console Variable: r.BinaryShaderCacheLogging). Duplicate & amend CL #3266053 from Trepka: Fixed issues with shader cache not working properly with Mac Metal (but it still requires -norhithread to work at all). Enabled the shader cache by default if RHI thread is disabled. Amend & integrate RCO's CL #3197085. Change 3267741 on 2017/01/23 by Rolando.Caloca DR - Detect duplicated shader and pipeline types Change 3268600 on 2017/01/23 by Uriel.Doyon Added missing r.Streaming.MaxEffectiveScreenSize config to base texture scability settings. Integrated CL 3227368 from Orion stream Enabled r.Streaming.UsePerTextureBias by default as this has been tested in Orion for several months. Fixed issue with the InvestigateTexture command which could return invalid reference depending on the timing, Added th MaxEffectiveScreenSize settings in the investigate texture command. Change 3269512 on 2017/01/24 by Richard.Wallis Fix for shader binary cache uncompress data size during internal shader log. Change 3271237 on 2017/01/25 by Ben.Woodhouse D3D12 updateTexture2D crash fix #jira UE-41059 Change 3271564 on 2017/01/25 by Olaf.Piesche #jira UE-40980 #udn 325525 Fix uniform buffers for mesh particles; these should really be on the mesh collector, so allocating them as a one frame resource is safe Change 3271594 on 2017/01/25 by Ben.Woodhouse ESRAM support stage 1: Implemented noncontiguous ESRAM page allocator replacing XgMemoryLayout API. The allocator allocates non-contiguous ranges of pages and maps them onto a contiguous virtual address range. Unlike the previous implementation, this allocator frees pages for reuse when resources are destroyed Note: issues with deferred deallocation may prevent reuse in many cases - that will be addressed in the next stage Support for the old allocator is still available (for now) via the define NEW_ESRAM_ALLOCATOR #fyi rolando.caloca Change 3272616 on 2017/01/25 by Rolando.Caloca DR - Update shader version Change 3273138 on 2017/01/26 by Ben.Woodhouse Fix merge issue with MonitoredProcess.cpp (this arose from an integration made as an edit in dev-rendering, which confused perforce when the change was subsequently integrated from main) [CL 3274498 by Rolando Caloca in Main branch]

Distance Field AO is now evaluated on a screen grid and using a global distance field for far traces * Screen grid resolution is 1/8th of primary resolution, but with 4x temporal supersampling through jittering subsample positions. A longer history filter is required to hide the jittering which can increase ghosting. * The main benefit of doing cone tracing on a screen grid instead of the previous surface cache is that it's performance is generally constant regardless of camera movement or noisy geometry (foliage) * A global distance field is now used for cone traces after a certain distance, DFAO is 2-4x faster as a result. * The global distance field is composed of 4 128^3 clipmaps that follow the camera around * Clipmaps are scrolled so that only new or dirty regions are updated due to camera or object movement, with close to 0 average GPU cost. Worst case update cost (camera teleport) is 5ms on 7870. * The global distance field currently breaks Distance Field GI * Overall with these changes DFAO in a Fortnite level is 3.4ms on a 7870 (3.8ms on PS4), and 4.0ms in the Kite demo on 7870.
