Compiz lag

view story

http://ubuntuforums.org – For some reason when I drag the windows around it lags, I have searched high and low all around the Internet for a solution but I cant find anything that works for me. I have tried to configure some settings in compiz with little luck but its better now then when I had the default settings but it is still laggy I tried to disable Detect Refresh Rate and set the refresh rate at 120(the monitor is 60) I disabled vsync in the nvidia settings but it is on in compiz, if it is not on in compiz i get crazy screen tearing So i was wondering if there is anything that I can do to make it better System (Hardware)
