If your software can handle fast enough refresh to match the refresh
rate of your monitor, that's the rate you want.  While the eye can't
really detect change faster than 50-60Hz, it *can* integrate a number
of too-fast frames into a single motion-blured image, which would
*appear* smoother.

If you can't refresh as fast as your monitor refresh, chances are
you're refreshing every other displayed frame (if you're vsync'd), so
a 72Hz monitor would refresh at 36Hz - too slow to simulate fluid
motion.
