I made the mistake of downloading new drivers for my 6990m from ATI - and ever since then I don't feel that performance is as good as it should be. It feels like the new drivers have made everything a little stuttery. I've tried downloading my driver pack from PCS but that doesn't seem to include the Graphics drivers, anyone know where I can get a good set of 6990m Clevo drivers from? Or should I indeed be using drivers from ATI?
