Microsoft Discloses DirectX 11 Features
- Full support (including all DX11 hardware features) on Windows Vista as well as future versions of Windows
- Compatibility with DirectX 10 and 10.1 hardware, as well as support for new DirectX 11 hardware
- New compute shader technology that lays the groundwork for the GPU to be used for more than just 3D graphics, so that developers can take advantage of the graphics card as a parallel processor
- Multi-threaded resource handling that will allow games to better take advantage of multi-core machines
- Support for tessellation, which blurs the line between super high quality pre-rendered scenes and scenes rendered in real-time, allowing game developers to refine models to be smoother and more attractive when seen up close
Tessellation and Displacement Mapping In Action
Support for tessellation is somewhat of a win for ATI/AMD, considering the Radeon HD series of cards are the only ones currently on the market with an integrated hardware tessellator. The hardware tessellator used in the Radeon actually first appeared in the ATI-designed Xbox 360 Xenos GPU.
Another thing to keep in mind is that DX11 will likely be the foundation of Microsoft's next-gen game console; the successor to the XBox 360. As more and more news and specifications regarding DX11 hits, it's a safe bet that they'll be supported by the graphics processor used in the next Xbox, if it is in fact called an Xbox.
