I wonder why our experiences are this different. What distribution of linux do you run, on which hardware and how recent is your experience? For what it’s worth, I have an AMD cpu and gpu with cachyos (which is a flavor of arch with some gaming optimizations pre-applied at install). I’d urge you to give it another try, Proton/Wine has really advanced a lot in the past few years.

Good news, an overwhelming majority does work fine, and a significant number of those actually run better than on windows. I just switched to Linux on my desktop pc (because of win 10 EOL and because fuck microsoft) and I’m amazed how smooth the experience has been.
