Do you actually have benchmarks and evidence showing that Wayland introduces latency over X11, or is it just a guess based on how you think Wayland works?

I mean, sure it might in some cases where you can use X11 to "directly" draw stuff on the screen, but most games would be double-buffering or triple-buffering anyway. I don't really see why Wayland would add any latency there, considering all the compositing is going to happen on the GPU anyway.

See my other posts where i explain why that would be the issue as well as how it could be addressed, but that would require hardware that AFAIK doesn't exist.

I do not have any benchmark as the only way i can think of for performing a proper benchmark that measures input-to-output latency would be using something like rigging a mouse to a robotic hand (or something like that) and capturing the screen output with a very high speed (e.g. 1000fps) camera. Sadly i do not have the necessary equipment for doing that.
