I have to update what I said. I too had to disable all AA in Skyrim and only use the built in FXAA. With any kind of regular AA on, I had blocks all over and even holes in buildings and trees. I never had a problem before and was able to use 4X AA in the game settings. Maybe I'll try forcing through Vision and see what happens. In WoW and Lotro, everything is fine and performance seems to be up some. Well, Skyrim is unplayable using any kind of AA other than the FXAA in the game settings. I don't know if it's the driver or the latest Skyrim update since I hadn't played since before that. With AA on, Whiterun looks like it was bombed with big holes in all the roofs and the map has artifacts all over it.
