EDIT Seems people have taken my comment as not being able to see a smoothness difference rather than not being able to act within 16 ms . If you need proof you cannot act within 16 ms , take a look at this online test to gather peoples reaction times the avarage reaction time is 277 ms with the median at 266 ms and that ' s when you ' re expecting to have to react quickly . Well . even at 60 we ' ve hit diminishing returns , not because we CANT notice a difference but that we are unable to process and then act upon those changes we see fast enough to make a difference . If we are talking just smoothness , there seems to be a market for 144 hz so it must be noticeable over 60 or even 120 hz . <| sep |> Yeah lucky you . I live in canada and it hasn ' t snowed in my town for a long time .
