I didnt do any ini changes to cause this and i dont think its a mod its been like this for a while. I just asumed it was because had shadows on low but i turned them up and the problem persists. Also ive reinstalled skyrim a couple times after having some mishaps with mods. You have two choices. 1) Turn land shadows in exterior cells off with the first edit, or, use the other lines to try and fix them. These didn't fix it :(
