Item (NB Cont.) Features
Support for GDI extensions:
In Windows XP and Windows Vista: Alpha BLT, Transparent BLT, and
Gradient Fill.
In Windows 7: Alpha BLT, Transparent BLT, Color Fill BLT, Stretch
BLT, and Clear Type BLT.
Hardware cursor (up to 64x64x32bpp), with alpha channel for direct
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
Full anti-aliasing on render surfaces up to and including 128-bit
floating point formats.
Support for OpenGLR 2.0
Anti-Aliasing Filtering:
2x/4x/8x modes.
Sparse multi-sample algorithm with gamma correction, programmable
sample patterns, and centroid sampling.
Temporal anti-aliasing.
Adaptive anti-aliasing mode.
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.
Improved quality mode due to improved subpixel precision, higher
precision LOD computations, and rotationally invariant LOD
computations.
Advanced Texture Compression (3Dc+. ):
High quality 4:1 compression for normal maps and luminance maps.
Works with any single-channel or two-channel data format.
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.
Up to 8K x 8K textures, including 128 bpp texture are supported.
