As Carlos said, this helps, especially the part about the games. I noticed long ago that there was quite a difference between what I saw as smooth animation and what I perceived as unnoticeable reaction time. And, since we started discussing frame rates, I have started to notice a slight flicker on the monitor, like that of a fluorescent (thank God for spell checkers) bulb.
It is easier to notice if you look with the edge of the vision field, ie, if you aim your sight outside of the monitor. The perifery of the eye has faster "sensors".
There are fewer cones (color-sensing retinal cells) away from the central visual field, so rods (more sensitive monochromatic retinal cells) dominate. Rods also have faster response times and so will create the perception of flicker even though the same source will not flicker when viewed in central vision. It's also the case that blue sensitivity extends further into the periphery than does red/green perception.
