OH, woops sorry, read your post a little too fast and miss understood.
I see you have a 8800GT so you need to go into your Nvidia Control Panel->Manage 3d settings->Program Settings tab and select the Divinity 2 entry and there is a drop down selection for Maximum pre-rendered frames. Set that to 1.
If there is no Divinity 2 entry in the drop down list you will have to Add it. I had to add mine.
