Pvs? Im not familiar with that method. Could you please explain further or point me to a tutorial?

PVS - For every leaf in your visibility tree, you precalculate every other leaf that is possibly visible from that leaf, and store the values in a lookup table. Obviosly the algorithm is complicated. I''ve never implemented a PVS caluculator, only used the data it generates.
