Some method to allow optiscaler to read the fsr4 files downloaded by proton?

I don't know if this is possible, but optiscaler cant use the fsr4 files downloaded by proton-cachyos using the fsr4 upgrade flag. it's probably expecting radeon adrenaline drivers.

I made a corresponding issue in the optiscaler repo https://github.com/optiscaler/OptiScaler/issues/632
