If you had a 2 or 3 yards wide TV monitor, with 24Hz refresh rate.
Watching tennis would be a pain.
The ball would jump in 5 inch (or more) jumps from left to right, and back.
With 120Hz or more, the ball flies in a curved, but connected, line.
The old mantra: a human eye can not distinguish reality from a 24Hz frame rate, is only true, if nothing particular interesting is happening in the 24Hz frame rate.
In a computer game, you anticipate where to shot at, for example. And that is based on your "perception". If you have a framerate, that deceives your perception, you are never able to aim accurately. Which basically boils down to: your accuracy does not matter. That is pretty odd, or? You aim as accurate as human possible: but the target is not there, because the refresh rate blurred it out of the cross hair.
