This card has an advanced Headcasting engine containing...

An Extended Vertex Shader
A DirectX 8 Palette Skinning Matrix
and Real-Time Accelleration for Photo Realistic Faces

These are great features but there is one downside (and a large one at that). This extended vertex Shader and Palette skinning matrix can only be used for communication using 3D Rendered Heads (more on that in a moment). This is the only thing it can be used in , it can't be used in games like the Geforce 3's Pixel And Vertex Shaders can.
