i totally agree. why isn't cheating actually illegal? nvidia should get sued for not providing actually what they tell their customers they do. since the radeon9700pro, nvidia has NOT provided any high quality drivers, or hardware anymore. and they cheated, used tons of marketings (nude dawn's etc) to regain the people, spreading out false-statements.

i'm very dissapointed myself, too. currently, i'm happy running realtime the dawn demo on my radeon with no problem faster than any nv30 chip as well, and more beautiful

Sorry for being pedantic, but just to be precise, "Appearance Preserving Simplification" is not the correct name of the technique. APS refers to a rather complicated way of simplifying a mesh in order to preserve the normal maps. The general technique used by ATI in polybump to build a normal map for a simplified object given a high resolution model, is called "detail preserving" and it is the one presented for the first time in:

P. Cignoni, C. Montani, C. Rocchini, R. Scopigno
"A general method for recovering attribute values on simplifed meshes"
Visualization '98 Conference Proceedings 1998, pp 59-66.

Guess I'll have to admit I'm as sloppy as everyone else. The real name is of course as you say, though many people sloppily refers to it as PolyBump.
Alright, I'll change it though.

Well said Humus, I totally agree. I think there should be an independent benchmarking suite that measures performance. Speaking in terms of OpenGL, it should use the standard ARB extensions instead of the vendor specific ones. This way developers will learn (mostly nvidia) to focus on the ARB standard rather than developing their own extensions.

You should probably use a different name for the technique, PolyBump is the name of a product, the name of the technique should be Appearance Preserving Simplification, or appearance attribute extraction. There are a lot of papers that refer to this technique with those names.

Wow.
The fact it makes shiluette computations much faster is probably the best thing about this.

Seems to me, that the only thing that needs focus now is decent silhuette... any ideas in that area?
