> and occasional gaming through Steam / Proton

And how does that work on AMD? I know the Steam Deck is AMD but Valve could have tweaked the driver or proton for that particular GPU.

I play lots of games on a AMD GPU (RX 7600) for about a year and I can't remember a game that had graphical issues (eg driver bugs).

Probably something hasn't run at some point but I can't remember what, more likely to be a Proton "issue". Your main problem will be some configuration of anti-cheat for some games.

My experience has been basically fantastic and no stress. Just check that games aren't installing some Linux build which are inevitably extremely out of date and probably wont run. Ex: human fall flat (very old, wont run), deus ex mankind divided (can't recall why but I elected to install the proton version, I think performance was poor or mouse control was funky).

Works very well for me! YMMV maybe depending on the titles you play, but that would probably be more of a Proton issue than an AMD issue, I'd guess. I'm not a huge gamer, so take my experience with a grain of salt. But I've racked up almost 300 hours of Witcher3 with the HQ patch on a 4k TV display using my self-compiled Gentoo kernel, and it worked totally fine. A few other games, too. So there's that!
