You can actually perceive at even higher than 60 frames - as I recall the upper limit was anywhere from 90fps(don't quote me on that figure) to 200fps (noted in tests with military fighter pilots). With higher framerates there is more information sent to the brain translating into a heightened sense of "reality."
In fact, a process, called Showscan, has been promoted by special effects man, Douglas Trumbull since the late 70's. Showscan was a new film format projecting 60fps of 70mm film. The resulting image is supposedly startilingly lifelike when shown to an audience - even more convincing than 3D or anything else witnessed on a big screen.
Taken from an article from the October 2003 issue of Digital Video. "24p: Back to the Future?":
"When Douglas Trumbull developed Showscan (70 mm at 60 fps) in 1976, he noted a profound psychological reaction among his test audiences when the frame rate hit 60 fps: The film ceased to be a film and was more like a window into reality. It just wasn't any good for storytelling, Trumbull claimed. Showscan was thus relegated to theme park immersive-entertainment venues, and a grand experiment in theatrical storytelling frame rates was shunted aside. (Of course, the scandalous print costs for 60 fps 70 mm could be part of the reason for the format's limited adoption.)....
...All analog television standards today employ interlaced rendering with a field rate based on the local power line frequency (or at least historically derived therefrom), and the power line frequency lurks in most DTV standards and production formats as well. NTSC broadcasts run with an approximate field rate of 60 Hz; the two most common HDTV formats in North American broadcasting are 1080/60i (interlaced) and 720/60p (progressive). All share that 60 Hz motion update rate that Trumbull found to be the dividing line between 'film' and 'reality.' ....Yet today we've learned to decouple production rates from display rates: 24 fps film appears on telly using 3:2 pulldown; high-end PAL sets often double-scan each frame for reduced flicker; frame stores let cameras capture 24p imagery and record it as 60i"
The reason why it hasn't taken off were due to the expense and practicality of filming and projecting 60frames of 70mm film - which demanded tons of film and extremely powerful projection bulbs, for instance. Recently his company filed for bankruptcy, which is a pity. I wish I had a chance to experience it just once.

So what's the big deal about 60 fps in film if that can already be observed in PC games? I suppose gaming at 60 fps or more isn't the same as film since you're dealing with the limitations of computer graphics which may or may not apply a convincing motion-blur for each frame (field), for example. The graphics quality, in this case, would be your limiting factor for a more convincingly "real" experience. Anyway, that's how I understand it.
