gamer!==gamer. These are your own choices. For me Assetto Corsa + other racing games + CS2 work perfectly. And with sway/i3, unlike in Windows, I can throw the game around in whichever way I wish. No laggy alt-tab or random crashes that my Windows user friends often have.
Simracing is the only reason my gaming rig runs windows. I never even thought my hardware would work on linux (especially my motion hardware). And stuff like crewchief and race telemetry. How do you deal with all that on linux?
