Make sure that P5 isn't still dumping excessive numbers of shadowmaps on your harddrive. That was a problem that was supposedly fixed, but then re-emerged sometime after the latest patch was installed on my machine and others. Cut down the number of lights that cast shadows to the miniumum possible, this will also help to speed rendering. Also check out that there are no single sided squares near the camera. This caused problems (excessive micropolygon subdivision) with early releases of P5, and there's some rumbling that this may still cause problems. Bill
