It's an obvious performance penalty, seen not as memory usage but as fps.
I've tryed the same scene (27000 objects) with planar circular surfaces
instead of spheres, and the performance was up to 3x faster. That's quite a
lot.

In conclusion, if you want speed (fps), use simple geometry. Use spheres
only when they are absolutely necessary.

Cheers,

Florin

See a post by Florin last week. He was drawing several thousand of
spheres at once...
But I guess a Sphere has (a lot) more vertices than a Cube(8) and this
has more vertices than a Cone(5) with a 4 corner base, plus apice (piramid)
