The upcoming refresh to the DirectX 10 API will be introduced as DX 10.1, ready to be released with Windows Vista Service Pack 1 (SP1). DX10.1 is based on the DX10 architecture and includes additional features and instructions to enhance rendering quality by providing improved filtering and anti-aliasing support. Some features that were optional in DX10 are now a mandatory part of DX10.1, including finer granularity of data access to improve data throughput and usage, and better standardization of the specification to improve third party application compatibility. These benefits will bring even more levels of image detail and rendering physics to bring us one step closer to reality on the PC.

The Chrome 400 Series can support new additions and features of the DX10.1 specification to facilitate the adoption of the next generation of improved games and applications.

DirectX 10.1 Benefits

Anti-Aliasing Enhancements:
In high resolution images and photo-realistic rendering, the aliasing effects of jagged lines and blocky
artifacts can reduce image quality as resolution and rendering frame rates scale higher. To mitigate these
unwanted artifacts, different anti-aliasing methods can be implemented to make edges and surface
transitions appear smooth and continuous. In the Chrome 400 Series, proprietary algorithms are
implemented on programmable filters to correctly filter, blend, and sample pixels to create smooth and
appealing images.

Image and Texture Improvements:
The technological breakthroughs of DX 10.1 provide support for higher levels of detail per scene, for increased density of application content, and for higher resolution monitors, such as widescreen and HD monitors which are increasingly prevalent in the marketplace. With HD image quality becoming the norm, the upgrades to the DirectX specification help make significant progress towards the goal of life-like image quality.

Strict API Standardization:
In the past, the DirectX 3D specification allowed hardware vendors to interpret the specification to match their specific hardware, causing problems such as performance degradation when there was no alignment between hardware and software application vendors. In the end, software developers would workaround this problem by using only the most common specification features and not incorporating any enhanced and optional elements. This approach limited the true range of 3D features found in the Microsoft standard. The stricter standardization being introduced with DX10.1 is necessary to resolve these hardware / software compatibility issues, and will enhance the user experience for all by accelerating the adoption of advanced 3D graphics in a greater number of applications.
