It's a misconception that the human eye can't distinguish between higher frame rates.
If it wasn't possible for the human eye to distinguish between 60Hz and 85Hz, how come the CRT monitor I used before moving to LCD had a very noticeable flicker at 60Hz (enough to give you a headache) but none at 85Hz?
A television set displays at 50Hz for PAL and 60Hz for NTSC regardless of fps. Even though movies run at 24 frames per second, when viewed on a television they are still being displayed at 50 or 60Hz. In other words it's displaying the same frame more than once.
