[Papervision3D] CPU usage metering?

[Memmie Lenglet]

You can't directly, but estimate CPU usage with frame latency (anormal interval between 2 frame due to CPU usage)

<code>
protected var lastFrameTime:uint = getTimer();
protected function renderScene(event:Event):void
{
	var currentFrameTime:uint = getTimer();
	//Frame rate
	var frameRate:Number = 1000 / (currentFrameTime - this.lastFrameTime);
	//Latency
	var frameLatency:Number = (currentFrameTime - this.lastFrameTime) - 1000 / this.stage.frameRate;
	//Use this for having latency compensation
	myDisplayObject3D.x += SPEED * (currentFrameTime - this.lastFrameTime);//SPEED in 3Dunit/ms
}
</code>

When frame latency is arround 20ms it low CPU usage, around 100ms is intensive CPU usage or more.
But i'm not sure for this values, NEED to be tested.
