This might come off as an easy way out to your question, but very simply I just don't bother with games that don't run on linux. There's enough really great titles that run great on linux, especially with the help of proton.

I can't be bothered with using windows anymore. It's so bad. It's very very bad, I rather do something else than have to play games under windows. I'll only use windows if I absolutely m must, like for when I'm at work.
