Not sure if this is the right place to post, but I can't think of anywhere else. I've had the same problem with Skyrim although that seems to have stopped. The problem is http://imgur.com/UMGAi4o where the shadows of things such as trees and, as in the screenshot, banners. I thought it may be the Overhaul's ambient occlusion, but it still does it even without that. I also checked in the nVidia control panel to see if there was ambient occlusion being run from there, but there isn't. I'm sure other people have had this problem but I don't know what it's called or how to fix it. Thanks
