What I remember from many decades ago when 8mm home movies were fashionable
is that a frame-rate of ~12 fps appeared as continuous motion to the human
eye & brain. On many of our systems we use either 8 Hz or 12.5 Hz update
rate and there's no apparent flicker at all. Trying to update a display at
30 Hz is useless because no one could perceive changes at that rate.
