A Plague Tale: Requiem not working with Steam + Proton (Arch Linux)

[darkbasic]

I've copied dlssg_to_fsr3_amd_is_better.dll, nvngx.dll and DisableNvidiaSignatureChecks.reg to ~/.local/share/Steam/steamapps/common/A Plague Tale Requiem:

I've run WINEPREFIX=~/.local/share/Steam/steamapps/compatdata/1182900/pfx /bin/wine64 regedit DisableNvidiaSignatureChecks.reg to apply the registry modifications.

I run the game with the Proton-GE (from the AUR) compatibility tool and with the mangohud %command% launch options.

No dlssg_to_fsr3.log is being created after I launch the game, nor any DLSS option is being shown.
