Nothing so much on locations mentioned above but for me the Red Rock Canyon area is almost unplayable. Nothing seems to help with this either. Only when i start to head back towards New Vegas it allways stops on same spot near the Great Khans armory building. After that it′s smooth again.
Granted, lots of npc′s wondering around there and so. Hope they fix whatever is causingh this on the patch...
Same as since the beginning, conflicts caused by odd features and functions added to Geforces since nVIDIA bought out the Ageia (PhysX) company and started trying to produce a super parallel CPU instead of just a GPU, as the primary purpose for the Fermi and immediately prior GT200's overall design.
