Reaction times and flicker fusion rates[0] are orthogonal. 0 ms latency at 8 FPS is different than 190 ms latency at 120 FPS. E.g. If there is an event that takes less than 125 ms, at 8 FPS there is a probability that you would miss it entirely! At 190 ms latency with 120 FPS, you would be guaranteed of seeing a 125 ms event, but processing of that information would take 190 ms longer.
