no, I think pierre is right with 15-20, television is @25 full pictures per second. but you cannot compare those values. On TV you have movement blur and those effects, therefore we don't need 60fps. but with a videogame it is different : you have no blur there, just sharp pictures. to have smooth movements, the human eye needs more frames per second. and I guess nobody doubts that 60fps looks better than 30 or even 20
