Today, I switched the last of my Windows machines to Linux: my gaming PC. I’ve been using Linux on servers for many years but was a bit apprehensive for gaming.
Turns out it just… works. Just installed steam and turned proton on, have zero performance or other issues. I’m using Ubuntu 25.04 for the 6.14 kernels NT emulation performance tweaks. Aside from there not being a catalyst driver for it and so I can’t undervolt my card everything is great.
Can you provide machine specs? Maybe you’re using an Nvidia card without drivers or something? Or maybe it’s a laptop and it’s using the wrong GPU?
Again, I agree with the first responder, make your own post so it gets more visibility and provide as many details as you can.
