FidelityFX SuperResolution for SteamVR games RC1
Changelog:
- fix for IL2 and possibly other games
- apply a negative LOD bias for texture MIP levels, as per AMD's recommendations. Might result in a bit more texture detail, hard to tell the difference, honestly
- "fixed foveated" optimization: FSR is now only applied to a configurable radius from the image centre, any pixels outside the radius are upscaled by cheaper bilinear filter. Even with a fairly small radius, it is often hard to tell the difference due to the current HMD lenses. Feel free to experiment with it and gain a few additional usecs for your frametime budget :)
