If it were done on a recent gfx-card, it would be called
tile-based-rendering ...

I simply subdive the area, I want to fill in smaller
ones, and only do inside these ones the collisiontest.
But that means, there "can" be collisions when two sub-areas
collide, especially when I specify a high density.

But I can't simply make the subareas smaller, and leave
a border around, because this would also make the tiles
visible...

I need to do some more experiments with that ...

BTW: here are 408000 spheres, distributed over 20x51
     patches with 400 spheres in each patch.
