Microsoft speaks DirectX 10

Microsoft speaks DirectX 10: "MICROSOFT finally saw sense and decided to drop Windows Graphic Foundation (WGF) and replace it with the more easier and logical DirectX 10 name for its nexgen API.
It gave some details to the developers officially about its upcoming API and we know that it plans to release this API together with Longhorn. Or Visa, as we must learn to call it.
The DirectX 10 API will have completely new and faster dynamic link libraries (DLLs) and is supposed to run much faster. The company decided to cut the backward compatibility with DirectX 9, 8, 7 and lower in this API but there will be a way to use games programmed for those APIs. Microsoft will enable support for DX 9 or lower games through a software layer, meaning it might run slower. "
