From my limited research and understanding, Nvidia makes Linux drivers, but they’re closed source. These work fine. They open sourced some stuff but not enough to really change much yet.
There are also FOSS drivers, but the performance for those vary.
Is this correct? Should I stick to proprietary drivers if I want consistent performance?
Yeah, I hate that shit. Thankfully, I trained my brain to hate non co-op multiplayer games. Anything competitive gets like 2 days max and then I delete it and play more Monster Hunter or something single-player. I think Splatoon 2 was the last competitive game I played for double digit hours.
