Wow, the numbers are entirely unexpected. I want to see the latency when you have no display server, having booted directly to a shell.

I imagine modern competitive twitch-reflex videogames (fps, fighting) must have far less input latency - 100ms must be totally unacceptable. Suppose that's the power of a GPU.
