I know, lame post, but I wanted to say that Linux gaming has gotten soooo much better, to the point that I honestly think my games are running better than on Windows. I've played so many games, but notable ones are Halo: MCC, MS Flight Sim 2020, Satisfactory, Mass Effect Legendary Edition, and right now I'm starting a full playthrough of Dragon Age.
Dragon Age is notorious even on Windows for being a pain because it's such an old game. You have to install the 4gb patch, and even then it's a bit rocky. Not on Linux though! I did have to install PhysX but I googled it and saw it was 2 buttons to install on Linux! Now it's been rock solid and stable, with no crashes.
Linux gaming may have a high bar to learn, but that bar is constantly getting lower! Exciting times!
I'm very aware of the tinkering involved, that's why I'm not telling people to "just install linux", but after futzing with Wine for 15 years now, I can finally say it's in a state where most things are plug and play. Yes, there are outliers that you kindly called out, but I'm very happy with the progress.
