Very possibly, Mick just meant that certain renderers (and 3D hardware) now
support a form of displacement mapping that is associated with on-the-fly
subdivision/tesselation/whatever, so that one can use low poly meshes and
"shape" them with maps. See for instance:
http://www.edharriss.com/tutorials/tutorial_xsi_text_displacement_map/extrusion.htm
http://www.rhythm.com/~ivan/dispMap.html
Other renderers (such as C4D) only displace the existing geometry so that
any necessary subdivision has to be done (selectively if possible) before
displacement by the user.
