Try doing delay(#ofmillisecs).
Alternatively if you want your app to always run at 30 frames per second, so it is the same speed on every computer, you can do:
timer=createtimer(30)
and then use
waittimer(timer)
to wait for 1/30th of a second to go by before you draw the next frame. This should keep your CPU usage down to normal levels.
