working hard to do a run-through of chaper 2 myself before releasing an alpha version. Still got a problem of major lag in two areas and not having much luck pinning down why (lighting might be causing one as I did go a bit overboard, the other just puzzles me...). Anybody got experience of lag in an area and any unsuspecting things that might cause it (i.e. other tha grass/trees, what are key culprits or things to check)?
