I have Win 7 64bit on my laptop which plays Skyrim very well, until I do windows update. After I update windows, the game still runs, but after about 20-30 min, becomes unplayable. I get infinite load screens, or sometimes very bad frame rate and slow game. Skyrim is latest update, and is not hacked etc. I have the game in my win vista 64 pc and do not have this problem. Both systems have 8 gig system mem, 1 gig video mem. Thanks for any tips or ideas.
