Get in a shop and look at the samples there. For me, i can't tell the difference between 30 and 60 fps, despite having 120% with glasses.

Btw, cinema effect (24 fps) is slightly over the conscious limit of 25 fps aka 40ms window. And TV series are fine with 30 fps. But the optical chain is in large parts independent and the optical effect that a still background light (vs CRT strobe on dark) doubles the required fps (70 to 100), so it can't be said for certain. Observation in a forum told me, that fps-sensibility is trained to a certain degree, with tasks/games where you follow the mouse or movements with your eyes (me a creative builder and programmer, rather than a competitive gamer or designer/CADler). But who knows.
