Sadly no (I already tried 3 to 2 and 10 to 2 - the number of drawables and primitive sets drops, but that's clearly not the bottleneck in this case). So I still go from 50fps to 33ish over EGPH with density = 1 .... not great (but flyable) One thing I did notice - you're creating a state set for each bin, based on texture. I think you want to globally cache those by texture (all the other parameters are fixed anyway, right?), so that OSG can see that all the prim-sets in different bins share a state set, and hence reduce state changes.
