# Upscaling: render the game at a lower resolution (thus saving performance), # then upscale the image to the target resolution to regain some of the lost # visual fidelity. upscaling: # enable (true) or disable (false) upscaling enabled: true # method to use for upscaling. Available options (all of them work on all GPUs): # - fsr (AMD FidelityFX Super Resolution) # - nis (NVIDIA Image Scaling) # - cas (AMD FidelityFX Contrast Adaptive Sharpening) method: fsr # control how much the render resolution is lowered. The renderScale factor is # applied to both width and height. So if renderScale is set to 0.5 and you # have a resolution of 2000x2000 configured in SteamVR, the resulting render # resolution is 1000x1000. # NOTE: this is different from how render scale works in SteamVR! A SteamVR # render scale of 0.5 would be equivalent to renderScale 0.707 in this mod! renderScale: 0.77 # configure how much the image is sharpened during upscaling. # This parameter works differently for each of the upscaling methods, so you # will have to tweak it after you have chosen your preferred upscaling method. sharpness: 0.7 # Performance optimization: only apply the (more expensive) upscaling method # to an inner area of the rendered image and use cheaper bilinear sampling on # the rest of the image. The radius parameter determines how large the area # with the more expensive upscaling is. Upscaling happens within a circle # centered at the projection centre of the eyes. You can use debugMode (below) # to visualize the size of the circle. # Note: to disable this optimization entirely, choose an arbitrary high value # (e.g. 100) for the radius. radius: 0.6 # when enables, applies a MIP bias to texture sampling in the game. This will # make the game treat texture lookups as if it were rendering at the higher # target resolution, which can improve image quality a little bit. However, # it can also cause render artifacts in rare circumstances. So if you experience # issues, you may want to turn this off. applyMipBias: true # Fixed foveated rendering: continue rendering the center of the image at full # resolution, but drop the resolution when going to the edges of the image. # There are four rings whose radii you can configure below. The inner ring/circle # is the area that's rendered at full resolution and reaches from the center to innerRadius. # The second ring reaches from innerRadius to midRadius and is rendered at half resolution. # The third ring reaches from midRadius to outerRadius and is rendered at 1/4th resolution. # The final fourth ring reaches from outerRadius to the edges of the image and is rendered # at 1/16th resolution. # Fixed foveated rendering is achieved with Variable Rate Shading. This technique is only # available on NVIDIA RTX and GTX 16xx cards. fixedFoveated: # enable (true) or disable (false) fixed foveated rendering enabled: false # configure the end of the inner circle, which is the area that will be rendered at full resolution innerRadius: 0.6 # configure the end of the second ring, which will be rendered at half resolution midRadius: 0.8 # configure the end of the third ring, which will be rendered at 1/4th resolution outerRadius: 1 # the remainder of the image will be rendered at 1/16th resolution # Enabling debugMode will visualize the radius to which upscaling is applied (see above). # It will also output additional log messages and regularly report how much GPU frame time # the post-processing costs. debugMode: false # Hotkeys allow you to modify certain settings of the mod on the fly, which is useful # for direct comparsions inside the headset.
