It started yesterday, only on The Elder Scrolls 4: Oblivion. Around the same time I did what I later discovered was a douplication glitch on a horse and got two of a sword. but now I deleted my save and reloaded and it still does it. It is slow in opening menus, performing actions, and loading areas. (It sometime has to load areas twice and for long periods of time) It is also slow at the main menu. I checked for scratches, cleared my HDD, and cried. But nothing works. Please help.
