#lockdown Nick.Penwarden #rb none ========================== MAJOR FEATURES + CHANGES ========================== Change 3250856 on 2017/01/09 by Daniel.Wright Only showing instruction count for 'Base pass shader' now Change 3250943 on 2017/01/09 by Rolando.Caloca DR - Async Compute PSO creation Change 3251036 on 2017/01/09 by Rolando.Caloca DR - Add r.AsyncPipelineCompile - Dispatch on any thread - Wait for completion event Change 3251058 on 2017/01/09 by Ben.Woodhouse Fix for PSO creation D3D error with NumRenderTargets. 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 |

Added the ability to apply DFAO to static indirect lighting, controlled by r.AOApplyToStaticIndirect
* Lightmaps, stationary skylight and reflection captures are all affected
* Specular occlusion on reflection captures requires a fair amount of tweaking of r.SkySpecularOcclusionStrength, MinOcclusion and MaxOcclusionDistance for good quality
* For now, a movable skylight with low intensity (.0001) must be placed to control MaxOcclusionDistance and MinOcclusion
