I daily drive Debian 12 on my desktop. In my massive library of steam games, I’ve yet to come across more than 3 that I haven’t been able to get to work, and the rest run remarkably better than on windows. Controller support has been more seamless than it was on windows, and I’ve gotten older games to work that never worked on windows 10. I’m not sure what experience you’re basing this on, maybe Optimus has some issues for laptops, but every desktop I’ve built in the last ~4 years has worked fine (and with nvidia GPUs, too)
