You haven’t tried it recently. Every game I play works flawlessly and is just as good or you can’t tell vs windows. I’ve been back and forth for 20 years and now I’m 100% and have been since February. I love it, and I’m happy to have my OS be my OS and do what I want it to do.
Now, to be somewhat fair, I built my new PC with the plan to go Linux. I went team red and a single ultra wide monitor. I wasn’t sure about the single monitor at all at first but now, man I love it. I have it setup so when I hit the windows key I can pick a new desktop. The only thing I can’t do is watch video’s while I play games and it doesn’t bother me at all.
