He was showing 100ms to 1ms, so yah of course, and he was drawing something. However, the video is interesting, but that's a completely different type of latency, the movement in that case is following a finger. With gaming, the movement is a change in movement or a start in movement, not continuous lag, lag only affects the actual changes since you are seeing past fluidity.
That video is not based on how fast someone can respond to a visual cue, that is based on how fast someone can see something refresh. Every test I've seen shows a noticeable difference at 30ms or greater, they've done double blind testing. People were not able to accurately tell a difference below that, could there be some god-reflex person that can tell 20ms, maybe but not enough people reliably in the testing I've seen. Even 30ms was like only certain people, most older people were around 50ms to even 70ms.
Are there instances where you can see the 15-20ms to 1ms differences, yah in refresh rates probably, but lag is more about response timing than having perfect motion.
