Another anecdotal tidbit:
Garsfield, outside LI shack. Can't see shack and other structures; failed to render. But I can see door. I go inside, do my LI business, and then exit. Presto every thing renders. So perhaps going through a loading screen forces a refresh.
Also seeing the behavior where very very close object do render, but mid-long range objects do not.
