(called “depth bounds”), and focusing calculations only on the
area most affected by the light source, developers can greatly
accelerate the shadow generation process. With the ability to
fine-tune shadows within critical regions, developers create
incredible visualizations that mimic reality, and still achieve
awesome performance for fast-action games. UltraShadow II
also works perfectly with NVIDIA® Intellisample 3.0 technology
to ensure that shadow edges are properly antialiased.
Superscalar 16-Pipe GPU Architecture
3DForce 6800 series includes a totally new superscalar shader
architecture, which doubles the number of operations that can
be executed per cycle compared to traditional architectures. The
result is a significant performance increase over single-shader
non-scalar designs. In addition, the new architecture provides
full 32-bit floating point precision—while still allowing for 16-bit
mode—so developers can deliver higher quality images in a
broader range of real-time situations. The superscalar design
also provides increased programming flexibility. Increased
performance, flexibility, and 32-bit native mode enable a host of
complex computations and pixel operations, resulting in an
unprecedented level of image sophistication in the latest
bleeding-edge games and other real-time interactive
applications. This technology delivers 8x the shading power of
previous generation products for screaming gaming
performance.
64-Bit Texture Filtering and Blending
Based on the OpenEXR technology from Industrial Light &
Magic, NVIDIA’s 64-bit texture implementation sets new
standards for image clarity and quality through floating point
capabilities in shading, filtering, texturing and blending.
Revolutionary innovations like 64-bit texture filtering and
blending allow for higher visual quality and more unique effects
by maintaining floating point precision in all aspects of rendering,
including shading, texturing, filtering, and blending.
The Industry's First On-Chip Video Processor
3DForce FX6800 series GPUs contain a revolutionary
programmable video processor that delivers state-of-the-art,
