@tek I've been messing around with a few options as a gamer myself. It's tricky. Nothing is quite 100%. For the best results I recommend something Arch based. I've gone back and forth and among the *buntu distros I'd recommend Mint for stability but for gaming with all the bells and whistles actually working, something Arch-based seems like the best way to go.
I liked Manjaro best as a good starter to learn the ins and outs. It has a lot of Just Works(tm) going for it right out of the box. Wayland and everything Just Works. I don't quite 100% trust the company and it sounds like they're leaning towards doing opt-out telemetry soon (or already?) which is a Very Bad Sign(tm). But it's a good start to learn Arch and then, from there, just go to Arch itself once you know it well.
