I use the Steam version with the -provider Portal launch modifier (lets me use my old ANet account)

Dropping by to throw some more praise onto the pile for Nobara Linux - it’s my current distro and I have an AMD RX 6700 as well. All the games in my Steam library work great, including Baldur’s Gate 3 (no tweaks necessary other than enabling the latest GE-Proton version). Unfortunately I haven’t played any of the games you listed; my preferences lean mostly towards RPGs like Elden Ring, Path of Exile, Guild Wars 2, Valheim (with mods!), Enderal and so on.

This, or the Tray Icons: Reloaded extension for GNOME, which adds the Steam icon to the tray bar. From there, you can click it and it shows a list of the installed games.

If you are new to Linux, GNOME has quite a different feel from your usual Windows flow. I personally love it and would never swap back.

(Off-topic, but If you would be interested in a gaming-oriented distro, I would recommend Nobara Linux - the official version looks fairly familiar for Windows users and it also comes with a bunch of gaming-related stuff preinstalled like Steam, wine dependencies, mesa drivers for AMD, etc)

Sven said in an interview they will try to get Steam Deck verification at launch or otherwise soon after
