I have the newest NVidia driver's. But in the display option's it has the place to turn off your Hardware Acceleration blacked out. Anyway to go around this or fix it?
What video card are you running? I have the 7900gt and I am able to do this system wide from the desktop. If you are unable to do it there, have you tried in a specific piece of software, like a game?
This website gives you the steps of how to turn it off.
