[QUOTE=Ashley] @Schoening - I'm not sure what your original question is actually asking, but in browsers which do support it, the main game loop is driven by requestAnimationFrame (otherwise a simple timer if not supported).
@andreyin - I think CPU ticks usually refers to a single cycle, i.e. 1 out of the 3,000,000,000 cycles per second in a 3GHz processor.
All you really need to know about "Every tick" is it aims to run 60 times a second, but if the system is slow it could run less frequently.[/QUOTE]
That still amazes me, 3 MILLION cycles a SECOND! I love technology.
