VRR is fantastic for games, I really notice the difference and I use Wayland because of it.
The downside to that is (from my understanding) Wayland forces some form of Vsync on everything, so if you don’t have a VRR monitor then games can become very stuttery and have noticeable input lag. There is an option to “force lowest latency” which supposedly allows screen tearing for things like games, though I didn’t test how well it worked myself.
If people are interested in experimenting, then VRRTest is a great utility to see what VRR is doing and to test various settings.
I believe we’re specifically talking VRR, which for me in Kubuntu did not work properly without switching to Wayland.
