I’ve nibbled at trying to use Linux on my home computer for years and years, but games didn’t have a good track-record in Wine so I never went over.
I recently heard differently, and tried PopOS, and I’ve mostly been able to get all the games I wanted to play to play, mostly using Steam’s own emulation using Proton, and a few using Lutris.
The only two that gave me trouble were Starfield–it had a bug with Nvidia cards and I had to wait for a Linux driver to be updated with a driver fix. (And honestly after playing Starfield, it wouldn’t have mattered if it never played.) And Crusader Kings III…but only if I had it playing natively on Linux, as it’s supposed to be able to. It kept constantly crashing if I clicked on a character portrait. When I switched to playing it on Proton (so emulating Windows) it’s been rock solid.
I’ve played No Man’s Sky, Cyberpunk 2077, Rimworld, Control, Alan Wake II, Baldur’s Gate 3, and Valheim all successfully. (And Starfield and Crusader Kings III after some troubleshooting.) Those are modern enough that I don’t feel any more disadvantaged gaming on Linux than I did on Windows (accounting for my last-gen hardware and such.)
