This has been bothering me for a long time when playing Skyrim. The only time it ever lags is when walking around outside. After you walk a certain distance, it loads more of the outside stuff, and that lags it pretty bad for a second or two and its really annoying. The thing thats puzzling me about this is that turning the graphics down does absolutely nothing. Even on the lowest possible setting it still does this. I have no idea what could be the problem, please help!
