If it isn't already set that way: You could try to run on an X.org session instead of Wayland. also CPU is more important than GPU actually. Try putting the CPU in performance mode.X.org didn't help. Performance mode will probably help some, I just didnt get to it yet, but I expected 30-35 FPS, since I have a 1440p screen. Maybe its the driver, currently I have 396.45 for steam proton and I saw 396.54 might perform better for games.
