Interesting results, in a nutshell it seems like Wayland/Xwayland performance on both nVidia and AMD wins slightly more than it loses. Once VRR is live in nVidia 545 series driver, for 3D games, Wayland is looking to deliver a great experience. Performance when Wine’s Wayland code is ready to mainline will be very interesting given that Xwayland needs will be negated at that point.
I have an 4080 TI, and bought a XTX 9700 so I could game on Linux without worrying about a thing. I’m planning to put that NV GPU on a second PC on X11 until Nvidia gets their shit together.
