From the very begining of skyrim If I set my AA to x8 there would be blue outlines on weapons when i was ever inside a particle effect such as dust, snow, ect. This also occures on most spells "mainly the restoration spells" as well as the cone of time at the throat of the world. This bug is fixed by turning AA off, but then of course the game becomes very ugly. Turning it to 4 removes some of it but I'd like to run the game at highest with out bugs like this occureing. Before anyone asks for a screen shot I'm use an nvidia gtx 560 and so far this only occures on nvidia models "AS FAR AS IM AWARE OF". Before posting responses, YOU try playing skyrim with AA at x8 and check the locations and spells I've specifid. Mabye you too have the bug as well. Please somone somehow forward this to a Bethesda dev so they can atleast adress it in the next patch. thanks -Nick
