Fixated on fps?

[DragonRR1]

The human eye can only really truly "see" 25 fps although this varies a little between different people BUT the eye does expect to see motion blur. A single movie frame displays motion blur since each shot is taken with a set exposure time so an object crossing across the camera has blur. This is effectively what happens when you see a racing car pass in front of you - your eye blurs the image of the car (if you keep your eyes still). If you don't keep your eyes still but track the car the road will blur. So... a movie looks smooth and gets away with 25 fps because there is blur in any tracking or passing shot....

Most computer games, SH4 as an example, doesn't apply motion blur. It displays frozen frames so the eye really does see 25fps as slow. As a previous poster said... at around 60 FPS (very dependent on individuals) the brain stops caring about the missing blur.

I should also point out that many people can see "flicker" on older CRT monitors at anything less than 85hz (85 FPS)
