Edit: Yo, I'm not saying this is gonna happen. I just want to say that Windew's UX sucks ass.
I've primarily been using PopOS, which has been fantastically stable and very easy. I have an all AMD system, but my understanding is that the nvidia version of Pop also makes some of the nvidia driver stuff a lot easier.
I also play on Arch sometimes, but realistically you probably don't want bleeding edge stuff if the point is just making sure games work. That's where the relative stability of something like Pop / Mint / even just pure Debian comes into play.
