Hello, I am using an Radeon 1950XT with 6.11 driver. I recognise an Bug when i starting ATITool 0.26 with the settings shown in the attachment. When i close the ATITool the Overdrive will not function anymore, that means the clocks stays always at the 2D speed when is playing a 3D Game! Is this a problem with the resume of the Overdrive? Also there is a problem with the option "Not affected". When I use this option and I open the ATITool once again after I have closed it my system crashes with vertical grey lines on the screen.
