On my xbox 360 version of the game, which i got brand new a couple days ago, the lag is HORRIBLE in any of the open wilderness places. Inside a building, the framerate is perfect, and there is no lag or anything. In a walled in city, the framerate is decent and it is usually running consistantly smooth. However, when i am in the great forest, or in the mountains, or any place outside of walled in citys and inside buildings, the lag is outrageous. It is completely breaking the immerision, and making quests awkward and buggy. If this is how it runs for everybody than i am appalled that this got GOTY.
