Re: [Algorithms] FPS Questions

60fps is the ideal target.

Instead of using a timer, what I do is add up the elapsed time from the previous
frame
until it is greater than 1 sec.  at that point I compute the average frame rate
and reset to
zero.

I do it this way because windows has a great deal of variance in the timer
function.  If you
use a multi-media timer you can get better accuracy, but at a cost of
performance.
