> By some estimates human beings perceive two events as instantaneous at around 100ms. This is not at all what the linked article says. The article says human reaction time — the time it takes to receive a stimulus, process it, and perform a physical act in response — is about 100ms. Human time perception is much faster than that. A software button that takes 100ms to switch to its pressed appearance feels dramatically different than one that does so in 10ms. As the linked article notes, game player performance degrades as latency increases from 13ms.
