I don't want to talk about other peoples experiences when it comes to games and graphics drivers on linux. I can just mention my own experiences with it. As a disclaimer I have used linux for years, just not as my main desktop.
Graphics drivers I have not had any issue with, they've been pretty plug and play. Games I've found can be a bit hit and miss, most will just work fine right away through proton or wine while others can require a bit of tweaking and troubleshooting to get running properly. I have yet to run into a game that just would not run at all however, but that could also just be that the games that wouldn't run are ones that didn't interest me already.
Friends are going to care if they're actually friends.
