You can try out the Proton-Cachyos with frame gen package if you’re on arch-based systems with pacman -U archive.cachyos.org/proton/proton-cachyos-1:9.0.20240928-1-x86_64_v3.pkg.tar.zst
or you can download custom tkg-proton with frame generation from mediafire.com/file/lv7d8jci0gyf6z0/proton_dlssfg.tar.zst/file and put into your ~/.steam/steam/compatibilitytools.d/
It’s actually really nice given the fps without framegen is playable.
I found it to have a positive impact for heavy titles that run around 40fps without it.
Anything below 30 gives this weird stutter
