Whatever, I'm just counting the time until I can drop windows entirely... right now I just need it for gaming, but I'm thinking maybe Valve's OS will be the replacement

I can't guarantee a great experience, but anecdotally my brother and I have had no issues in the last ~12 months playing all types of games on Linux. Only games which require kernel-level anti-cheat are unavailable. Otherwise, Proton and native clients (when available) have been rock solid, and I've been surprised that some games (like Minecraft) actually run much better than in Windows.
