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 switched to wayland full time last month, and everything is working well
If only gnome will add the vrr on it :/
