Honestly Steam and Proton have solved like 90% or more of this issue, i was in this spot in the past for a long, long time, but Steam has made this work almost seamlessly for a great number of games
And then i got the Steam Deck and this went into overdrive
At this point i feel like Linux is a realistic option for a gamer, qualified of course (anti-cheat tech tends to break things, plus there's a few problematic ones), but we are at the point where you can buy an AAA title and be relatively confident it will run on Linux (check first though)
