fsr4 PROTON_FSR4_UPGRADE Automatically download amdxcffx64.dll and upgrade games with FSR 3.1 to use FSR 4. Version to download can be specified by supplying it as a value, like so PROTON_FSR4_UPGRADE=“4.0.1”, instead of 1. Downloads version 4.0.2 of the required DLL by default. This option also disables AMD Anti-Lag 2 currently due to various issues.

fsr4hud PROTON_FSR4_INDICATOR Enable the FSR4 watermark at the top left portion of the screen.

fsr4rdna3 PROTON_FSR4_RDNA3_UPGRADE Identical to PROTON_FSR4_UPGRADE but for RDNA3 GPUs. Enables some required compatibility options and downloads version 4.0.0 of the DLL by default.

fsr3 PROTON_FSR3_UPGRADE

dlss PROTON_DLSS_UPGRADE Automatically download and use newer versions of nvngx_dlss(d|g).dll DLLs. Version to download can be specified by supplying it as a value, like so PROTON_DLSS_UPGRADE=“310.2”, instead of 1, to download version 310.2.1.0. This option also sets DXVK_NVAPI_DRS_SETTINGS to use the latest preset. If you provide your own config for it through this environment variable, your configuration is going to be applied…

dlsshud PROTON_DLSS_INDICATOR Enable the DLSS overlay at the bottom left portion of the screen. This is exactly the same as FSR4_WATERMARK=1
