I''m trying to find information on some of the more obscure aspects of graphics development. I''ve used OpenGl and DirectX in the past but neither of those APIs are useful for what i want to do. Basically i''m trying to make a tool that collects and displays information about the graphics card. I want to include such things as core and memory clockspeeds (the DXDiag API doesn''t provide this). The utility so far http://members.iinet.net.au/~paulglasson/gpuid.exe Anyway what i need is information on accessing the graphics card without DirectX or OpenGl (specifically for nVidia cards but i''m interested in other cards as well). Does anyone know of such documentation?
