At a glance, there appears to be almost no rendering performance difference vs standard normal mapping. Seems like it would be feasible in realtime engines. Baked normal maps are commonplace now in leading game titles. AR/VR stereoscopic views would make anisotropic surface effects, diffraction, etc even more obvious for those micro details and really help sell the illusion. Very interested in seeing Cars 3 in 3D to test this hypothesis...
