I uninstalled Windows few years ago even though I play the latest AAAs and indies games, including in VR, that's how good Linux for gamers.

You can check my post history but basically once you have your hardware well supported (basically the right drivers) and rely on a good system to evaluate compatibility (e.g. ProtonDB) then you won't get any surprise.

I suggest though that you try it yourself, e.g setup a Linux distribution of your chosing, a game you already own and... see if it feels good. If it does not, feel free to ask around and people will be happy to help if you provide a clear problem with your documented attempts to fix it, at least you can count on me.

So... finally why did I change? Well beside the "it actually works" it is also a lot more coherent with my own WorldView and my skillset. I'm a professional developer, WebXR prototypist to be more specific, so having an OS that does not put arbitrary (well, mostly about control for profit) limits on what I can or can not do is simply better. I can play for fun AND I can tinker with the same OS. I don't have to reboot if I just happen to have an idea that I want to try, I can just do it right here and there.

TL;DR: it works and it's better, giving me all the freedom I need to be creative and not feel constrained.

PS: also not giving more money to multibillionaires from Microsoft does feel nice.
