Erm, sorry, but I think you're getting confused here. The virtual displacement mapping is either parallax mapping, or some variation on it, not normal mapping.

mh? what's that technique called? (sorry if it has already been discussed on the forums, but I've been away without the net for 4 weeks, and I didn't yet have time to look through all that has been posted since :) )

Quote:*real* displacement mapping get proper silluettes. It change the mesh in function of the diffuse map. (If someone is not ok with that please, say it ;))

You could modify the depth of each pixel in the fragment shader based on the height map to get real displacement per pixel. Not tested this, but it should work.

Early z reject will be disabled if the fragment z is being modified.

What do you mean by messing up early z rejection? Early z reject will be disabled if the fragment z is being modified.
http://www.delphi3d.net/ has a demo doing z-correct parallax mapping and horizon mapping. But the fragment level z displacement is an approximation which still does not fix the silhouette problem.. it makes intersections look better though.
