X11 works perfectly fine and is recommended when possible, however wayland has a large drop in overall fps and consistency. When using wayland it stutters an extreme amount when playing with an unrestricted framerate (vsync does not work to fix this). To fix this go into game and enable performance overlay. Go into firing range and pay attention to the overlay (not mangohud). Note what your minimum fps is. Mine fluctuated between 120 and 150. Exit game and use steam launch options to cap the framerate below that minimum fps number. I did 110. This should resolve your stuttering issue.
