If you wanna game and want everything to work, get bazzite, i wanted to install arch, had huge probs with my nvdia card (i know, but it was gifted with the cudas in mind) so i used bazzite since i loved the steam OS look. I am so pleased, it works amazingly, and there was 0 problems during installation.
Perfectly understandable. Any anti cheat is a big nono on this system. But tbh, i am so much more relaxed after stopping league i consider it a bonus guardrail XD
