There’s no doubt that Flash 11′s new Stage3D API can produce some amazing results by giving us access to the power of the user’s video card/GPU. However, it’d be a mistake to blindly assume that it is always faster than the traditional Flash display list (i.e. Stage). Today’s article begins a series that discusses the topic of “draw calls” and how they heavily impact the performance of your application.

Stage3D Draw Calls: Part 1

Simple 2D With Stage3D
Jan 23
Along with Flash Player 11′s new Stage3D class have come hardware-accelerated 2D rendering engines. Impressive results have already been demonstrated by advanced engines like Starling and ND2D. Today’s article shows a simple Stage3D-based sprite class to help learn more about how these engines are implemented and provides a simplified alternative to the more complex 2D engines that still delivers hardware-accelerated performance.
Holding DisplayObjects
Oct 25
I recently received an e-mail from asking which is faster: a DisplayObjectContainer or a Vector of DisplayObject. To ask this is to question whether or not we can do better than the Flash Player’s native container of DisplayObjects using AS3. It turns out that we can. Read on for several ways to improve on DisplayObjectContainer‘s speed.
The Size of Empty

I was reminded about the flash.sampler API by Grant Skinner’s recent post about it. While only available in the debug player, it can still tell us some valuable information about what goes on in the release player. Today I’m using the getSize function to find out how much memory overhead various classes impose, even when they are empty.
Shape vs. Sprite
Oct 26
Flash 9 and AS3 provide a lot of nice structure that Flash 8 and AS2 lacked. Instead of just MovieClip and TextField, we have a whole hierarchy of DisplayObject derivatives, including MovieClip and TextField. Most AS3 programmers know that Sprite is a more efficient class than MovieClip and have grown to use them when animation is not required. However, I find that very few AS3 programmers ever use some of the other, more obscure DisplayObject derivatives. Today I’ll talk a little about one of them: Shape.
