Has anyone else noticed how when you are driving there are patches that are black, blue, and sometimes red that require you to be closer before they load in and the whole time i am seeing grid lines in the surrounding area. I have done every fix i could find try every combination of graphical options and nothing seems to resolve this. I have the most up to date drivers as well. Is this happening for anyone else?

I specs are: 8gb RAM
AMD Phenom x6 2.8ghz
ATI Radeon 5770 HD

Oh man does this issue bother me! Like you, I've done so many things to try to get rid of this. EVERY TIME I exit an interior area into the wasteland I see blue polygons on the tops of just about every mesh.
I'm really surprised that there are not more threads on this because it's such a common bug whenever I play. Hopefully we can get some feedback soon.
