What games are you playing and what hardware are you running?
Linux has come a long way regarding the ability to easily play games made to run on Windows. It’s never been so easy and well performing. However, in my experience, it’s not quite “just works” yet. Yes, some Windows games will “just work,” but for now that’s still the exception to the rule in my experience.
I use Arch btw, with a i9-9900 and an Nvidia RTX 2070. I still have to tweak settings, research what others are tweaking, I have a few hours of research and tinkering invested into stopping up close jitters in VR(still unresolved), my graphic settings have to be lower than normal for decent performance and I do not enjoy the same frames I’ve enjoyed on Windows with this same machine.
I could probably get some better performance squeezed out of these games, but it’s going to cost me time and tinkering.
tl;dr I don’t think we’re in “just works” territory yet, but we’re getting closer and the progress over the recent years has been amazing. I can’t wait to be rid of Windows forever.
