Beats me, but I've seen people post on ACC on how to do this.

I usually keep track of the number of game loops since the start of the 
game. I use this for some logic functions that span multiple update 
cycles, or (potentially) for checking synchronisation between 
client/server or debugging.
Not a big deal, since it's easy to just have another variable++ at the 
start of each logic loop, but a bit wasteful if there's one available 
already.

Bad idea. You shouldn't redraw the graphics if nothing has changed on 
screen during the last logic loop.

I'm not sure if you're refering to Lennart Steinke's installer/setup 
distribution?
