Recently my Skyrim game has been running horribly. The load times take anywhere from 2-5 minutes and it is lagging constantly. I've had the game for several months now and it has never run like this before. I'm running it on low settings with the antialiasing and anisotropic filtering off. I have reinstalled twice now and am running no mods. Specs Processor: AMD Athlon II X4 635 Processor 2.90 GHz Ram: 6 GB Operating System: Windows 7 64 bit Graphics: ATI Radeon HD 4300/4500 Series I'm about to buy a new graphics card because I know that mine is pretty bad, but it has handled Skyrim on low settings before. What should I do?
