I was wondering, i am curently making a full screen flash game.

The problem is that will all effects on, the game lags (obviously)

BUT

My cpu does not run at 10% neither does my memory

Does flash activeX has a limit of processing time / memory usage ?

Why does it lag if it could take more cpu time ?
