I have a desktop computer that I use for gaming so it had windows forever. Lately it started running laggy. Occasional frame drops and stuff. Reinstall, bios update etc nothing helped.

For debugging I installed Bazzite (Linux gaming distro) assuming compatibility would be shit but I can at least test native linux builds of some games to see if there is a hardware issue. The thing runs perfectly. I've been playing propert windows games on Proton with higher / more consistent FPS. It is kind of funny at this point. Granted I do not play any competitive / multiplayer games.

I guess Valve did a great job on the Steam Deck sw.

I've been running Fedora (or a flavor) on my gaming PC for two years. All my games work. I understand some competitive games with intrusive anti cheat are incompatible, but with the success of the steam deck I don't think the gaming argument is holding much water these days.

Fair. Depends on the game to be honest.

I switched from Windows 10 to Fedora recently. Most of the games I play work without issue but I know there are some which categorically refuse to work (mainly some specific anti-cheating software reasons).

Do you play fortnite? Steam's linux support is really good but I kept a Windows install for a couple of years so I could keep playing fortnite.
