CSG seems poorly bounded by default.  Are you rotating or scaling the CSG?
If so, try a scene without these transformations and see if there is an
improvement.  Also try it with more objects (>1000).

Light/Vista buffers are too tightly integrated with the bounding box
hierarchy to be easily adapted for use with the BSP tree, at least for now.
 I'll need to give some more thought to how a screen space hierarchy could
benefit with the tree.  There are other things that will improve
performance more which I am going to try first (such as construct better
bounding boxes for csg).
