Onboard Components
The GeForceFX possesses two integrated 400 MHz 10 bit RAMDACS. Each can output a signal to a CRT at a maximum resolution of 2048x1536@85Hz. The TV-Out functionality has been included in the chip itself. Although 10 bit color support per channel has been present since the first generation of GeForce boards, only a very few lucky users will be able to profit from it, since monitors that can display more than eight bits per channel are very rare.
DirectX 9 Features, Shaders, And Cg
The concept of Cg.
The greatest strength NVIDIA sees in the GeForceFX are its pixel and vertex shaders, which go far beyond the DirectX 9 specification. So what exactly is a shader? A shader is really nothing more than a program - a modifier that calculates effects and applies textures to an object. Shaders themselves are nothing new. Aside from the editors, the routines in ray tracing software are basically a rather large collection of shaders, which are then applied through the editor.
