Image Quality: AA and HDR
Coverage Sampling Antialiasing Technology
Advanced new antialiasing technology provides up to 16x full-screen multisampled antialiasing quality with the performance impact of 4x multisampled antialiasing using a single GPU.
High Dynamic Range (HDR) lighting capability in all GeForce 8800 Series GPUs now supports 128-bit precision (32-bit floating point values per component), permitting true-to-life lighting and shadows. Dark objects can appear very dark, and bright objects can be very bright, with visible details present at both extremes, in addition to rendering completely smooth gradients in between.
HDR lighting effects can be used in concert with multisampled antialiasing on GeForce 8 Series GPUs, and the addition of angle-independent anisotropic filtering combined with considerable HDR shading horsepower provides outstanding image quality. In fact, antialiasing can be used in conjunction with both FP16 (64-bit color) and FP32 (128-bit color) render targets. This means that those ATI boys don’t get to have all the fun now with their “Chuck Patch.”
Quantum Effects GPU-based Physics
The gaming world is on the verge of something huge with the coming of Physics technology. While AA and HDR give you pretty graphics to look at, physics is set to advance gaming into another realm of realism and immersion. Physics will provide lifelike movement of hair, fur, and water. Objects on the screen will be swept away by giant tornadoes and when you launch that RPG into a brick wall instead of the tank you were aiming for the wall will come tumbling down.
Much of this technology can be simulated and rendered much more effectively by the GeForce 8800 graphics processor. By offloading this to the GPU, the VPU is freed up to run the game engine and AI.
