Color Combine Unit
Highly programmable
Virtually N x N or N + N color combine modes
Unique color iterator per texture
Iterate specular w/o performance cost when multi-texturing

Texture Array bump mapping track the light in true 3D

rather than DX7’s 2D
Dynamic bump mapping: using 3 or more textures
Smooth bump mapping: Smooth seams across polygon edges.
Procedurally generated effects
The more textures the better
Having flexible recursive texturing is critical, and makes the effects look substantially better.
The generality of the math unit allows it to dynamically generate particle system effects (not just play back of movies or CPU generated data) such as fire and explosions.
