Hi Christian, To profile the peformance bottleneck it would be best to press 's' a couple more times to get the full frame rate stats so you can see exactly which parts of rendering are the bottleneck - the frame rate only tells that you frame rate is reducing it doesn't give any clues to why.
In terms of optimizing performance I'd be inclined towards trying out using draw instanced support. Not all cards support this, but it would help with draw lots of identical geometry with the only different being it's position in space. Robert.
