My second article about DirectComposition is now available in MSDN Magazine:
The Windows composition engine represents a departure from a world in which each DirectX app requires its own swap chain to one where even so fundamental a construct is unnecessary. Sure, you can continue to write Direct3D and Direct2D apps using a swap chain for presentation, but you no longer have to. The composition engine brings us that much closer to the metal—the GPU—by allowing apps to create composition surfaces directly.
