support of Windows XP, Windows Vista andirons 7 alpha cursor.
•
3D Acceleration Features
•
Fully DirectX 10.1 compliant, including full speed 32-bit floating point
per component operations
•
Shader Model 4.1 geometry and pixel support in a unified shader
architecture:
•
Full speed 32-bit floating point processing per component.
•
High dynamic range rendering with floating point blending, texture
filtering and anti-aliasing support.
•
High performance dynamic range computations

Lossless color compression (up to 8:1) at all resolutions, up to and
including widescreen HDTV.
•
Anisotropic Filtering:
•
2x/4x/8x/16x modes
•
Up to 128-tap texture filtering.
•
Adaptive algorithm with performance (bi-linear) and quality (tri-linear)
options.

HW support to overcome "Small batch" issues in CPU limited
applications.
•
3D resources virtualized to a 32-bit addressing space, for support of
large numbers of render targets and textures.
•
New vertex cache and vertex fetch design, to increase vertex
throughput from previous generations.
•
Full support of 64-bit and 128-bit textures and surfaces, which can be
4x to 8x faster than previous generation of HW.
