As an intermedia Linux user prior to making the jump 2 years ago, if you mainly game on Steam you're fine. Wine and Proton are mature developed now that most games 'just work'. Almost all the problems I've run into for gaming on Linux have come from trying to do something outside steam (although Blizzard and Activision games seem to be pretty low effort).

Once you get outside that, it's hit or miss (sometimes good hits. Sometimes bad misses).

What you'll have to say goodbye to is alphas, betas, and release weekends. They CAN function (I did all 3 Diablo 4 beta weekends last year with no issues at all), and there's plenty of early access stuff on steam that works fine even though the developers didn't care about Linux one bit. But usually if you're reporting issues on opening weekend for a new game, they're more concerned with making their game launch work for the 95%+ of users instead of the 5%. If you want stuff to 'just work' and don't want to spend your weekend tinkering with waiting for hot fixes or patches, you'll probably not want to make the switch. Or will want to change your mentality about which games you play and when.

That being said, the experience is constantly getting better. So in a year or two it may be a different story.
