Hi guys. I have recently started modding my saved game. All was good till i tried to add texture packs. Without texture packs my frame rate is an average 60 fps, lowest about 40-45. First i tried Skyrim HD mod which was giving me frequent drops to single digit frame rates. Then i tried the official skyrim high res texture pack. This just seems to drop to 1-5 fps every now and then for about 10 seconds. Any ideas? Yes i am a noob to modding. I'm using a core i7 930 @3.2ghz and 2x gtx460's. Could SLI be the problem? Other mods I am using: realistic ENB, realistic lighting, SkyUI, Lanterns of skyrim.
