I did get the “Processing vulcan shaders” pop-up sometimes when I opened the game (back when it was still working) So I should not be using the Proton experimental? It worked just fine untill now. That’s what’s so strange about it. I do have an old PC but my GPU is brand new though.
I’m trying to re-install steam right now but it’s been uninstalling it for about an hour and doesn’t seem to be progressing anywhere…
