I feel like this game should be able to crack 40-60fps fairly easily considering it’s ten years old, but for whatever reason I can’t seem to get it above 30fps and keep it looking decent. Someone said that the game runs closer to 60 when using Proton 7.0.4, but it looks like I’m unable to get that proton version anymore from the compatibility options available within SteamOS.

Would really just like to get this game running at least at a stable 40fps, does anyone have any suggestions for settings, proton versions and the like? Currently only using Proton Experimental.
