After 30 years on windows I recently switched my gaming desktop over to linux mint. So far proton has handled every game I've thrown at it with only a minor FPS hit. Do note that I only play older games so if you are a bleeding edge gamer it will probably be harder for you. But the peace of mind I get from not being tied to the spyware infected microsoft ecosystem has been well worth it, and the only cost was backing up data from windows for the switch, and the inevitable linux fiddling that's required.
