Well, gee, that makes a lot more sense. Dean, if you're reading this, the last column in that chart I sent you a year ago should read "3.5 million" and not "10 million." :|
I made a note about that in the usage screen of GLXspheres. I think I should further modify it so that it allows the sphere count to be adjusted. It was kept static in order to guarantee that the same image was always generated. Note that there are actually 61 spheres in the default configuration (20 per ring + the 1 in the center), so apparently the polygon limit is around 60,000 per sphere. It might simply be that the polygon count is clamped to a 16-bit value or something.
