why is only 60 fps really smooth in cocos2d?

Question

It has probably been asked before, but I can\'t find it anywhere...

In videoland, 24 fps and anything above is smooth. Cocos2d seems to be smooth only when its 60 fp

Answer 1

Two main problems.

First is matching the refresh rate of the display - anything else and you get irregular motion which the eye/brain is good at spotting. At least be at a multiple of it.

Second is motion-blur. Film/video tends to have motion blur, which fools the viewer into seeing continuous motion.
