This is much less a Linux problem and much more a communuty one. We really need a semi-centralized place to get recent linux info and a nice guide on linux specific knowlage for beginners, but then people will cry needing to learn what wayland/x11 and such are will turn people away. Whoever was telling you windows games 10-15% faster were fucking dumbasses, I have zero problem running any game I want on my machine but the preformace has been exactly the same as windows (which I still consider a win for linux)

The next big problem is people going “We don’t need gaming distros” when those gaming distros are made to solve this exact problem. If you haven’t already try out Bazzite or Nobara and it might “just work” (no promises tho). But a distro like Mint/Pop/Debian are going to have a lot of missing drivers/package updates for the latest hardware, Fedora needs relatively a lot of post-install tinkering to get things working since they only ship opensource packages by default, Garuda is not ment for beginners and uses a more unstable kernal for preformance, but you still need to tinker with drivers. Bazzite and Nobara are the two big distros that aim to “just work” out of the box and even re-package some software with the latest fixes. And incase you don’t like the look of them, you can install whatever theme over KDE Plasma you want

Ofc I get if your tired of hearing “just install this distro instead” but a lot of advice is coming from others who also don’t actually know whats going on under the surface, and sometimes your hardware just isn’t supportes (not a linux issue but a manufacturer one). And if your at the point where using windows for gaming works and thats enough for you, nothin wrong with just using windows
