hmm, if no AA nor +Q2 change much I imagine there must be a humongous amount of

Probably won't do much either, but you could try halving the resolution as well.
 And grouping the spheres in unions, as a last resource...

I don't think there's anything much faster or memory-efficient for this kind of
problem (huge amounts of spheres) than a raytracer.
