Linux is legit at 99% nowadays, and you actually have to hunt for examples where compatibility leaves a game at unplayable. I think something like Call of Duty might still be weird, just due to anticheat. Give it a shot; you probably won't revert back to Windows.
The vast majority of issues I see people have with Linux nowadays are actually with Gnome; its generally really good, but it can sometimes cause some instability, and I've found Kde to be more pleasant.
Yep, and for games with anticheat, you can check this list[0] to see its compatibility with Linux. I've been running Gnome under Fedora for years, and the times I need to boot into Windows are becoming rarer as time goes on. It's usually just for flavor-of-the-month live service games that eventually get Steam Deck verified anyways.
Hey, thanks for sharing, I had no idea. If you don't mind, what distribution do you recommend if you wanted to play a couple games and have as low-hassle as possible good power management?
The Deck has a recovery image that's linked to from that page. But if you're building your own machine, can it still run the Deck image or is this version more appropriate?
Yeah these days I'm mostly playing either Helldivers 2 or Call of Duty. I used to play a lot of Warframe and Overwatch. My experience was that Overwatch worked great (a bit slower than Windows on the same hardware but still fine) while Warframe worked pretty well but crashed on the large maps (the open-world-ish stuff). Call of Duty didn't run at all (anti-cheat as you said). I haven't tried Helldivers 2 yet as I currently have a dedicated Windows machine where it's installed.
