I did a little bit of research and looks like the patch I posted does primitive substitution like L3P, by increasing the number of segments for round primitives. Technically L3P uses real primitives like spheres and cylinders but you could consider them infinite segments.
>From what I understand primitive substitution in LDView doesn't actually increase the number of segments for each primitve but instead smooths the normals between them so you don't notice the discontinuities in lighting when you have 1 normal per face. Since we don't have lighting this method wouldn't do anything noticeable but maybe they also increase the sides per primitive as well. This is from a quick look so I could be wrong.
