There's lot of copies of data to and from shared arrays. Even when the screen saver is off, the check to see if data needs to be copied is a non-zero overhead. There are optimizations that become difficult when the graphics code is enable. The lab is having network problems, so I can't currently get you a speed ratio of the no-graphics to graphics versions. It would be difficult to add graphics back into the versions that don't currently have it.
