This was put in at the direct request of application developers who
were complaining that their scenes were running at greater than 100
frames per second and chewing up all of the CPU time needlessly. The
intent is to allow an app to set a speed limit of, say, 1/60 or 1/30 of
a second.
If what you want is the fastest possible frame time, then yes, it isn't
useful to you.
