Isn't it just a card limitation? afaik you have to edit and flash the bios to get 2d/3d clock changes working on an 8800 gtx.
i tried that on my 8800gts and it didnt work 4 me it might work 4 others tho i had to set up my 3d/2d/fan profiles in the launcher+overclocking/fan pages and the set it to monitor hardware acceleation and set it in the schedualer to launch the 2d/3d profiles wen game starts/stops
But it wont work with ATi 4870 Cards correct ? Because the HardwareAccelration Plugin is greyed out in HardwareMonitoring, i cant acces the Plugin. No HardwareAccelration = No 2d/3d auto clocking ?
Hardware acceleration graph can be reported by statistics server and it doesn't depend on hardware. So it can be used with ATI too.
