Used automated or manual install?

• Automated
• Manual

Launch parameters: PROTON_USE_OPTISCALER=1 PROTON_ENABLE_WAYLAND=1 PROTON_OPTISCALER_CONFIG="Plugins.LoadAsiPlugins=true" %command%

If on AMD/Intel and Automated, used DLSS inputs?

• Yes
• No

Used Optipatcher?

• Yes
• No

Also please mention in description which upscaler inputs are used (which upscaler you selected in game settings).

Did you check the Wiki and Compatibility List?

• Yes
• No

Please describe the issue and steps to reproduce it

While all other settings work fine from my testing, trying to change the output to FSR 3.X/4.X causes an instant crash, when it should be using int8 FSR4 (per CachyOs-proton). To note, this type of crash actually triggers Palworlds OWN crash debugger, so I have attached the files of that.
UECC-Windows-882858CB40A8FA1CD8A966ADF30396D1_0000.zip

Game only natively supports DLSS, so DLSS input.

I have attached

• [] OptiScaler.log (set LogLevel=0 and LogToFile=true in OptiScaler.ini, zip it if too big)

Despite setting launch params of: ``PROTON_USE_OPTISCALER=1 PROTON_ENABLE_WAYLAND=1 PROTON_OPTISCALER_CONFIG="Plugins.LoadAsiPlugins=true;Log.LogToFile=true" %command%`` , no log file was generated.

• Screenshot of game folder _(where you placed Opti)
  Based off https://github.com/CachyOS/proton-cachyos?tab=readme-ov-file#optiscaler-integration. Though it strangely does not match the "default" name as cachyOs says.

• Screenshot of Opti overlay in-game (opens with shortcut, default Insert)

OptiScaler 0.9.4 with proper FSR 4.1.1 support should fix this issue now.

[thegreatGreenstar]

testing with 0.9.4-final (7534ad0) this still occurs

[TheRazerMD]

Without an actual Opti log, this is all guesswork. Might be the usual Proton overriding our internal settings. Did you set the Fsr4ForceEnableInt8=true in OptiScaler.ini as recommended?

Another option, I'd recommend completely disabling the integrated OptiScaler from Proton, installing it manually in the correct folder (dxgi.dll should work fine) - Pal/Binaries/Win64/ and trying also with Fsr4ForceEnableInt8=true in OptiScaler.ini.

If still crashing, set LogToFile=true, reproduce the issue and send the log here.
