I can recall it being used as a useful benchmarking tool once it got 
multicore.

If you use so many triangles so that each are smaller than a screen 
pixel, you lose no more accuracy than any pov primitive.

In any cases, you get it wrong:  the amazing speed up is not due to 
native GPU triangle handling, but faster ray intersection calculations 
thanks to the GPU sheer parallel vector processing.  You can see that in 
smallptGPU where you get perfect math spheres much faster, no meshes in 
sight.
