What I need is to be able to retrieve information about the graphical
capabilities of a system in OpenGL (C++). I can already retrieve the
name of the video card through glGetString(GL_RENDERER), and I use Cg
profiles to check for the availability of vertex and/or pixel shaders on
the video card. But I would still like to retrieve some extra
information. In particular , is there any way I can retrieve the clock
speed of the video card installed in the system? Or does anyone have any
other ideas which might be helpful/useful for my goal?
Thanks in advance!

looking at the extension string might be useful for you as well
i don’t think that there is a way of knowing the exact clock speed. i
don’t know why you would in the first place. you could build a database
based on the cards name (or chipset). usually custom code paths are
implemented for the chipsets. like one for the NV30 and one for the
R300, etc. you know what i mean
