I read that people who play a lot of FPV shooters have higher than average reaction and perception time. 18ms is ridiculously fast though, I’d be surprised if someone could consciously register it. I know gaming monitors market latency in the 1.5ms range, so maybe elite gamers can perceive the difference. Someone else pointed out that there are concerns over latency stacking between all of the devices, and that’s a really valid point.
