Really cool research. Overall, X11 still wins compared to Wayland(kwin) but only by 0.14 - 0.22 ms. The really bad performance hit is from XWayland which added 3.13 ms.

You underestimate how short 100ms really is. Animations of 200ms feel snappy, anything less and you can leave the animation away.

    I'm well aware how short 100ms really is and it is very obvious if your inputs are off by 100ms or more; rhythm games are rarely that strict, but I've also played games where some inputs had to be timed to within 1/60th of a second (~16.7ms)
