When I set 3D overclocking, save, then go to 2D it has the overclocked values from 3D setting before. When I set 2D overclcking (meaning want to used default clock or lower), save, then go to 3D prformance oc it has the values form 2D. That means for this simple task that the graphics card throttles down in 2D, I have to make two profiles and a switch in hardware monitoreing? True. or only needed to add special things like fan speed or voltage changes.
