You don't need anything higher then 60 for the human eye can only proccess information at 50 FPS, but it sounds like some cvar is restricting it (I don't remember the 1.6 cvars).
It's 24fps, not 50.
But if you train your eyes you can sometimes see interlacing on tv's.

tv's have 30 fps in NTSC regions, 25 in PAL, 24 in cinema (used to be), I assume your eyes are as slow as the lowest value.
Well, if I just turn it down to 29 fps it clearly laggs in my eyes. 30 fps ain't that smooth either.
