Kyro 2 SE enT&L

From ParaKnowYa's Q&A with Hercules

Q, Can you give us more details on the "Enhanced T&L" in the 4800? Is this hardware or software and, if its software, is it faster than the 4500?
3D Prophet 4800 enhanced T&L is a software process enhanced by the Kyro hardware. The Kyro hardware sorts the surfaces & 3D objects of the angle of vision, eliminating invisible triangles prior to applying the transform and lighting, and these sorted 3D objects are animated & lighted in software T&L. The benefit compared to the 4500 traditional software T&L goes up to 15% additional fps in games limited by the geometry. Games limited by the fill rate, as Quake III, will be boosted with 3D Prophet 4800 by its faster clock compared to the 4500.

Sounds like a lot of geometry goes over AGP repeatedly - maybe that's why it won't work on STG4500.

Also, wouldn't this hardware sorting make hardware T&L on PowerVR more efficient than on an IMR?

oooops scratch my former answer I thought I read software T&L in your question....
