Let me elaborate. I have spent quite a lot of time providing voluntary tech support on Reddit and forums. In both of them you will see people having a blast & praising the community, and people pulling their hair due to frustrating issues right next to each other. Having the same OS or distro does not guarantee the same experience. People have different hardware, run different software and play different games. Also, choices regarding compat layers can make a difference, for example someone forces Proton Experimental on all games and it works out, while sb else uses Proton stable and it doesn’t work. Or the other way around. Oh, also don’t get me started on my Linux experience, it’s a roller coaster.

I don’t know if you’ve used Windows lately, but you get the GPU drivers on a fresh install (if you’re using a remotely mainstream video card).
