问题
Is ENTER_FRAME always received, even if another process occupies the CPU, OR the listener might miss one or more ENTER_FRAME events -then receive several of those events delayed in a batch as usually happens in Windows?
(I'm using pure AS3 and Stage3D with 3D GPU rendering -no 2D display objects, Flash timeline, movieclips etc).
回答1:
ENTER_FRAME depends on frame rate. And frame rate is not a constant - it depends on a lot of factors, few of which are CPU and GPU. The listener won't miss anything, it's just that the ENTER_FRAME event will be dispatched irregularly.
