1. Yeah, AA isn't working. No NPC shadow here either, so I assume that that's normal.
2. Same, the self-shadowing is just low-res.
3. Unchecking the shadow timeslice update WILL have a serious effect on performance. Timeslice updating means that the shadows won't be updated in realtime, so their just static decals. Unchecking that means that you get dynamic shadowing at a sizable performance hit.
4. Not really familiar with that problem.
5. That's pretty common, as I think the leaves on the trees are randomly generated.
6. I WISH.
