Assetto Corsa Competizione VR Graphic Settings - loz-archer/youtube GitHub Wiki

Last Updated: 26th June 2025

PC Spec: Quest 2 (5408 x 2752 x 72) / 7950X3d / 4090

Note: I will continue to tweak these settings over the next few weeks to find the right balance of clarity/performance.

I have also amended some values which aren't available within the game:

[ConsoleVariables]
r.Streaming.FullyLoadUsedTextures=1
r.Streaming.MipBias=-1
r.MipMapLODBias=-1
r.MaxAnisotropy=16

I have applied these to the bottom of the following file: C:\Users\{{ YOUR USER NAME }}\AppData\Local\AC2\Saved\Config\WindowsNoEditor\Engine.ini

What do they do?

r.Streaming.FullyLoadUsedTextures

A powerful Unreal Engine setting that tells the engine to fully load all visible textures to their maximum resolution, rather than loading lower-quality mip levels and upgrading them over time.

  • 0: Default behaviour
  • 1: Textures in view are fully loaded immediately to their highest resolution which prevents popping, especially in VR. It uses more VRAM, but gives better visual fidelity, especially at distance.

r.Streaming.MipBias

Another Unreal Engine variable that adjusts how aggressively texture streaming chooses lower-resolution mipmaps.

  • 0: Default behaviour
  • -0.5: Slightly sharper distant textures
  • -1: Sharper, forces higher mipmaps sooner
  • -2: Very sharp, higher VRAM and CPU usage

r.MipMapLODBias

A variable in Unreal Engine that controls the bias level when choosing mipmaps, directly affecting how sharp or blurry textures appear at various distances.

  • 0: Default behaviour
  • -0.5: Slightly sharper, mild GPU cost
  • -1: Much sharper, especially on signs/track edges
  • -2: Ultra-sharp, high GPU usage, may shimmer

r.MaxAnisotropy

Controls anisotropic filtering in Unreal Engine — a technique that improves the clarity of textures viewed at sharp angles, like road surfaces or trackside signs.

  • 1: Blurry
  • 4: OK
  • 8: Good
  • 16: Sharpest

I keep vertical sync off in all games as I control that via the Nvidia control panel where I have "Max Frame Rate" locked to 72 fps to match the Quest 2 headset.
