I don't like to quote myself, however:
[total crap deleted]
If you prefer, you can google "Flicker Frequency Threshold", or simply ask your eye doctor.
While you're at it, ask you optometrist if they believe that crap. If they do, then they never took a sensation and perception course in their life.
If that crap you posted were the only aspect, then those of us who see RGB artifacts in DLPs wouldn't experience that. Also the level of refresh required depends alot on the situation, the image, and the method being used to display/convey the image.
Second, fluro lights illuminate on the peak and trough of the sinus waves, therefore they fire at 120hz, also the coating on fluro bulbs has a latent illuminative quality, both of these lead to vary rare situations where we notice them and its usually only with sympathetic flashes that it becomes an issue, unless of course the ballast is F'ed up and you have exaggerated effects.
Many many aspects are involved in the appearance of fluidity, including contrast, brightness levels, image sharpness, convergent motion, level of sequential image divergence (similar frames are easier to make fluid than those with more differences), angle of solid lines, and angle of motion, also whether or not you look straight on at something or use more of your peripheral vision (rods are more sensitive than cones).
(1) 30 FPS is MINIMUM acceptable gaming. (This means NEVER dip below, regardless of conditions).
(2) 45 FPS is adequate.
(3) 60 FPS or more is imperceptable.
Actually that's a false rule, since it depends alot on the game or scene as to whether or not 30fps is the min.
For something like Splinter Cell and other creeper style games 20fps would be fine because the need to refresh the scene and the view of the player is limited.
Whereas twitch FPS games have alot of motion and also require higher refresh rates to reduce the impact of entire scene motion. If your character is jumping while turning, you need far faster refresh to have fluid motion and proper visuals. Also remember that when doing something like a 180degree turn you need high refresh rate to paint scenes correctly so that you even achieve minimal refresh for the range of motion.
Effects like motion blur help reduce the number of frames required for fluidity, but it also reduces the level of accuracy for FPS games.
