Hmm...This is really bizarre.
I know some people have had random crashes, but I think this is the first complete failure to load the visuals for that scene that I've seen. That rig shouldn't have issues running the game. You meet the specs.
It doesn't actually crash, right? If it were crashing, I'd say to attach the crash log. (You can try walking around a bit or leave it a moment and see if that triggers anything...?)
Another option would be to try making sure your video card driver is up to date... But it seems really weird that you would be having this issues there and not anywhere else. You can try fiddling with the other settings, too, and see if that helps. Shadow distance causes issues for some people. I know some people have also resolved weird graphical glitches by disabling SSAO, so that's another thing to try.
I'm about tapped for suggestions at this point and it's getting late here, but one of our other (more tech savvy) community members / moderators may have some additional suggestions. If we can't figure it out, hopefully Team RTG will be able to offer additional suggestions after Easter.
