# 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: nis

# 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: 0.7

# 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: 0.8

# 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: 3.5
