Some of the new modes and enhancements include:
• Gamma correct rotated-grid antialiasing which removes jagged edges from 3D images while maintaining the highest level of color reproduction on your monitor.

• Transparent supersampling and multisampling which minimize the undesirable visible aliasing that occurs in highly detailed textures. The improvement in 3D image quality can be most visible when viewing outdoor scenes and objects such as vegetation and chain link fences in games.

• Increased subsample coverage and a new texture core which accelerate 64-bit floating point texture filtering and blending to deliver full-speed, state-of-the art high dynamicrange (HDR) lighting effects. This technique, used in professional film rendering by companies such as Industrial Light & Magic, delivers complex, ultra-realistic lighting effects to hot new games.

Mind-Blowing Performance
Built to deliver mind-blowing graphics performance, the GeForce 7800 GPUs feature a next generation superscalar architecture and an all new NVIDIA® CineFX™ 4.0 engine. The CineFX 4.0 engine includes a redesigned vertex shader unit that shortens the time required to set up complex geometry processing. In addition, a new pixel shader unit delivers up to 2x the floating point shading power of previous generation products, while an advanced texture unit incorporates new hardware algorithms to speed filtering and blending operations.

All of these features combine to deliver advanced visual effects at unimaginable speeds. The GeForce 7800 GPUs are designed to reach even higher levels of performance through NVIDIA® SLI™ technology. With NVIDIA SLI, you can combine two GeForce 7800 GPUs in a single system to scale performance by up to 2x . Through an intelligent combination of software and hardware, NVIDIA SLI is able to offer this unbelievable performance on over 60 of the top PC titles. If you’ve ever dreamed of running id Software’s DOOM 3 at 90 frames per second, NVIDIA SLI can make your dream a reality.
