The problem is that GPUs, in their current form, are great for
processing triangles but not much else.
POV-Ray, on the other hand, uses a wide variety of geometric primitives.
There *was* a version floating around that did a tessellated preview
using OpenGL. While functional, it never really caught on (AFAIK, the
prevailing method of a quick preview is to #declare several identifiers
specifying quality levels at the head of your main .pov file).
