Framerate issues on monster system

[WhiteKnight]

Thanks for replying back. On Windows XP I had not noticed the lag so far with the SSAO set to High, EXCEPT when I load this saved game. Although I am not very far into the game however. However, on Windows 7 the game lags when SSAO is set to High so there seems to be an issue with somethiing in Windows 7. Also, how can I turn off Aero in Windows 7. I selected the Windows 7 Basic theme, does that turn off Aero. Even with Windows 7 Basic theme (and presumably this turns Aero off) the lag exists in Windows 7 with SSAO set to High, but does not lag in XP.

Thanks again. When I get home I will attach the save game that gives me lag even in XP.
