I've only ever heard displacement mapping being applied to NV40 and not the R420 so I presume it doesn't feature displacement mapping.

I've always thought you needed vertex shader 3.0 to do displacement mapping?

You can do displacement mapping without VS3.0. VS3.0 lets you do it entirely within the vertex shader, which is, presumably, a lot faster than other implementations (although I *still* haven't seen any numbers on how fast NV40 can do it).

Parallax mapping is supported on r300+ if I'm not mistaken. Following this Thread at OpenGL.org. It looks like a pretty cool technique, and I ran offsetmap, uberbump and the demo by Humus.

That looks pretty good.

I saw where they had it running on a GF2 card, but to really see the effect, you need ARB_fragment_program and ARB_vertex_program OGL extension support. It does look great, I think we'll be seeing alot of this going forward.
