In the past (in METAL) I have always measured elapsed time between loops, multiplying the velocities by elapsed time to move sprites.

I have switched to Cocoa, and done some animation with fixed frame rates using NSTimer and NSThread. How can I run the loop as fast as the machine can support it?

Set the timer to a very, very small interval (like .001 - a thousand times a second).

set it to zero or negative
Zero or negative values get translated to the smallest available interval.

Really? Cool.
