Change 2719147 on 2015/10/07 by Mark.Satterthwaite
Allow the shader cache to perform some precompilation synchronously on load before falling back to asynchronous compilation to balance load times against total time spent precompiling. Added a stat to the group that reports how long the precompile has been running until it completes so it is easier to track.
Change 2719182 on 2015/10/07 by Mark.Satterthwaite
Refactor the ShaderCache's internal data structures and change the way we handle recording whether a particular predraw state has been submitted to try and make it more efficient.

Merging CL #2729846: On OS X unconstrain windows from the dimension of the parent display when in Windowed mode - it is OK for them to be larger in this case. They do need to be repositioned if on the Primary display so that they don't creep under the menu bar and become unmovable/unclosable and Fullscreen windows still need to be constrained to a single display. We can now take screenshots of windows that are larger than the display & not get grey bars beyond the cutoff.

This should be marginally quicker as it stops a double call to ClearState().

Change 2732018 on 2015/10/16 by Mark.Satterthwaite
Emit a shader code cache for each platforms requested shader formats, this is separate to the targeted formats as not all can or need to be cached.
- The implementation extends the ShaderCache's hooks in FShaderResource's serialisation function to capture the required shaders.
- Each target platform has its own list of cached shader formats, analogous to the list of targeted RHIs. Presently only the Mac implements this.
- Code cached shaders are now compressed (for size) to reduce the overhead associated with keeping all the shader code around - this works esp. well for text-based formats like GLSL.

Added the ability to merge the .ushadercache files used by the ShaderCache to store shader & draw state information.
- Fixed a bug that would cause invalid shader membership and draw state information to be logged.
- Added a separate command-line tool to merge shader cache files, currently Mac-only but in theory should work on other platforms too.
Change 2735226 on 2015/10/20 by Mark.Satterthwaite
Fix temporal AA rendering on GL/Mac OS X - you can't rely on EyeAdaptation values unless SM5 is available so only perform that code on SM5 & we must correctly clamp saturate(NaN) to 0 as the current hlslcc won't do that for us (& is required by the HLSL spec). The latter used to be clamped in the AA_ALPHA && AA_VELOCITY_WEIGHTING code block that was removed recently.

Audio Optimization: Implementing an audio update delta time so audio isn't updated with every engine tick
Change 2746582 on 2015/10/29 by Aaron.McLeran
Implementing single ray-cast sound occlusion
- Fixing/Implementing sound occlusion using one ray cast
- Update rate of the ray cast is conifgurable by the user
- User can enabled/disable occlusion and set various properties of the occlusion at the audio component level
- Occlusion ray-casts are made at a slower rate than the audio engine is updated
- The following properties are supported:
* LowPassFilterFrequency (the LPF cutoff frequency of the per-voice filter to apply if a sound is occluded)
* OcclusionVolumeAttenuation (the volume attenuation to apply to sounds that are occluded)
* OcclusionInterpolationTime (how fast a sound moves from occluded to unoccluded... allows user-defined interpolation times, avoids fast parameter setting for smoother transitions)
- Fixed how low-pass filter frequency is applied on platforms that support it.
* Changed the older HighFrequencyGain parameter to a more understandable and correct LowPassFilterFrequency parameter
* Updated the parameter for the various other features that use per-voice LPF (e.g. audio volumes, distance-based filtering)
* Added backward-compatibility code to take old HighFrequencyGain params to new LowPassFilterFrequency params.
* At the lowest level, there is only one filter which is applied to a sound, but the parameter that has the lowest cutoff frequency is the one used
* Fixed how the parameter is applied at the lower-level in XAudio2 and CoreAudio. The old parameter was incorrectly applied.
* XAudio2 documentation on the low-pass-fitler frequency cutoff param is confirmed incorrect through testing.

UE-23091 More fixage for NaN audio log spam
Last checkin for this (CL 2760896) was fixing a legit issue but there was still an issue that I was rarely catching during the FN gate encounter in AITestbed after about 5 min of gate defense.
To track down, I added a lot more logging and asserts on NaN numbers in the audio code, enabled ENABLE_NAN_DIAGNOSTIC in UnrealMathUtility.h.
- Was able to trace another cause of the NaNs in audio to 2 uninitialized variables in SoundAttenuationSettings struct: OmniRadius and StereoSpread.
- Zak M suggested the change of the const ref position vector in ListenerPosition and the usage of GetSafeNormal() in Audio.cpp since the value returned by GetLocation() is a temporary and Normalize() is unsafe.
- I removed the flag for the XAudio2 call to compute doppler since we don't use that value and it could've been as source of more NaNs in X3DAudioCalculate

multiple materials/chunks on a single cloth sim mesh
This supposedly used to work in 4.7 but broke for 4.8
It looks like previous change 2493547 may have introduced the condition statement that makes multiple materials not include all of there verts.
Changing this to instead check for the bounds on the skinningmap instead of the NumRealSimVerts which doesn't look like it takes the offset into consideration.

- Issue was caused by 2 issues:
- effect chains weren't properly clearing their state between uses (SetEffectChain(nullptr) releases the effect for use with other voices)

FCollisionQueryParams constructor API pitfall
Deprecating something that will call the unintended constructor if the programmer provides a string literal instead of explicitly creating an FName.
So this line of code:
FCollisionQueryParams Param(FName(TEXT("DragDropTrace")));
will invoke:
FCollisionQueryParams::FCollisionQueryParams(FName,bool=false,...)
But this line of code:
FCollisionQueryParams Param(TEXT("DragDropTrace"));
invokes:
FCollisionQueryParams::FCollisionQueryParams(bool)
Yes that actually happens, the string literal (the TEXT("whatever")) ends up specifies a bool parameter instead of a FName parameter. So the name is lost and a flag (that is usually set to false) is now set to true (since the string literal address is non-NULL). Yeah, that's could potentially be not what the programmer had intended.
It looks like this interface was introduced in CL 1792949
back in august 2013. Since its been a couple of years, we'll phase it out using the deprecation approach.
Making an API change would break things for existing projects.
If it had been a more recent change we could have probably just gone down to a single constructor right away.
Figured out that going one step further and removing bool param's default and adding a default constructor would minimize the number of places that will be hit with this deprecation. So, yes this is *increasing* the number of construtors temporarily, but this solution has minimal impact on the community. Later after other to-be-deprecated constructor gets removed, the two remaining can be combined into one with defaults for all parameters.
