I have a very good PC and my oblivion is updated completely in every way. I'm not a noob to modding at all but this is an issue I've never even heard off. For some reason any object added from a mod in the world space occasionally turns black and slows down my PC to the point were I have to save and restart the game. When I load the game back up the object is no longer black and the game works fine until it happens again with another object. It doesn't matter which mod it is but body replacers do it the most. If it was a rare occurrence I wouldn't care but it happens so often the its making my game unplayable. I know that if your missing a mesh it does a giant exclamation mark and if your missing a texture its purple beneath. But why are objects turning black?
