Skyrim.
Ok So Whenever I used to play skyrim on my computer it was absolutely amazing with no lagg at almost full settins, however after I had to whipe my hard drive and reinstall everything I try and play it and its just obnoxiously choppy and annoying now, all my drivers are installed and Syste, Requirement labs is telling me I should be able to run it with no lagg at all, but I have no idea whats going on right now, any suggestions at all?
