I have Dirt 5 and Hogwards Legacy and I am not able to make them work the gnu/linux… Both have “gold” in ProtonDB, I’ve tried the last Steam Proton and Proton-GE and nothing… They don’t even start. I try to throw them with Heroic Game Launcher.
With Cities: Skylines 2 or Cyberpunk 2077 I can play well.

Any ideas?

I use Fedora 38 Gnome
