If you play a lot of competitive multiplayer games, it would be better to keep a windows partition for them (overwatch is the only game that I had a good experience on Linux).
I used to play some competitive Apex, I was overjoyed when I heard anti cheat support is available on Linux, and quickly installed it. I tried it a couple of times since then, the most recent being last month - The game is playable but not on a competitive level imho. The smoothness is just not there. Then again this might be because of my low spec hardware.
Games like Valorant just won’t work because of their kernel level anticheat. (But hey we have Conter-Strike 2 now)
AAA games run just fine for the most part, its playable and I usually get performance similar to windows.
