Although geometry looks convincing enough, I think we may have to be careful as the more illusion of 3d geometry that's generated from the textures, the more quality itself seems to be put at risk. Also the relief mapping that fpo had made distorts horribly at angles, though he says there's a lot of optimisation he can do so i look forward to that. However AFAIK, the feature seems to only support nvidia cards due to the supposed requirement of a very large number of, mostly dependant, texture look ups to which ATI cards only supports 4 in a single shader.
