- [Audio]
- iAudioCacheSize=8192
- iMaxSizeForCachedSound=2048
- Change INumHWThreads to the number of threads your CPU has
- If you do not know how many threads your CPU has, use CPU-Z to find out
- fXenonVertLookSpeed and fXenonHorizLookSpeed can be removed if you do not run the game in a 16:9 aspect ratio
- Repeat for the Testing profile
