I accidently discovered a way to solve it and not lose your save. Go to your saved games and begin uninstalling the game. At roughly 10-15% i had second doubts about wanting to lose my lvl 10ish character I already had so I cancelled. When I looked again, it prompted me to "install" again and when I loaded up the game the texture bugs were gone and it looked normal, it's loading abit slower since it isn't on the hard drive but I expected that. So uninstall, cancel about 10-15% through, and just reload where you left off. I hope this worked for you and others as it was just an accidental coincidence that created the fix for me.
