"G80" To Feature 128-bit HDR, 16X AA

More G80 features abound
As if we mere mortals needed
more reasons to be excited about G80
, here are a couple more tidbits: 128-bit high dynamic-range and antialiasing with 16X sampling.
The high dynamic-range (HDR) engine found in GeForce 7950 and Radeon series graphics cards is technically a 64-bit rendering. This new HDR approach comes from a file format developed by Industrial Light and Magic (
the LucasFilm guys
). In a nutshell, we will have 128-bit floating point HDR as soon as applications adopt code to use it.
OpenEXR's features include
Higher dynamic range and color precision than existing 8- and 10-bit image file formats.
Support for 16-bit floating-point, 32-bit floating-point, and 32-bit integer pixels. The 16-bit floating-point format, called "half", is compatible with the half data type in NVIDIA's Cg graphics language and is supported natively on their new GeForce FX and Quadro FX 3D graphics solutions.
Multiple lossless image compression algorithms. Some of the included codecs can achieve 2:1 lossless compression ratios on images with film grain.
Extensibility. New compression codecs and image types can easily be added by extending the C++ classes included in the OpenEXR software distribution. New image attributes (strings, vectors, integers, etc.) can be added to OpenEXR image headers without affecting backward compatibility with existing OpenEXR applications.
NVIDIA already has 16X AA available for SLI applications. The GeForce 8800 will be the first card to feature 16X AA on a single GPU. Previous generations of GeForce cards have only been able to support 8X antialiasing in single-card configurations.
This new 16X AA and 128-bit HDR will be part of another new engine, similar in spirit to PureVideo and the
Quantum Effects engines
also featured on G80.

The bottom line is the politically correct EPA needs to start regulating the politically correct Nvidia and there huge power sucking SLI bullshit and cards. Quad SLI and everything.
The liberals already control what cars we can drive, you can bet they're going to start controlling what computer you can have too.
Watch this post get modded down (censored) at light speed for speaking the truth (but I dont care).
I love it when too politically correct things clash, like Apple and Nvidia, or the EPA and Nvidia.
