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.

Stage3D Upload Speed Tester

Since Flash Player 11′s new Stage3D allows us to utilize hardware-acceleration for 3D graphics, that entails a whole new set of performance we need to consider. Today’s article discusses the performance of uploading data from system memory (RAM) to video memory (VRAM), such as when you upload textures, vertex buffers, and index buffers. Is it faster to upload to one type rather than another? Is it faster to upload from a Vector, a ByteArray, or a BitmapData? Is there a significant speedup when using software rendering so that VRAM is the same as RAM? Find out the answers to all of these questions below.
