Using Cg and OpenGL on old graphics card?
I have an IBM T40P laptop with an ATI FireGL 9000 64 MB graphics card:
http://ati.amd.com/products/Mobilityfgl9000/index.html
It seems that this card only supports OpenGL 1.1 which is the version that
pops up if I run OpenGL Extensions Viewer. Is my card to old for programming
with Cg and OpenGL?
I have some code that calls:
cgGLGetLatestProfile(CG_GL_VERTEX);
which just returns a unknown vertex type. This error does not occur on
another machine with a Nvidia GF 7600GS card.

Hmm, I'm pretty sure it supports more than OpenGL 1.1 -- sounds like you are
getting the Microsoft software OpenGL and not the fglrx driver.

The graphics card is more than 5 years old so I guess its the reason that it
does not support a higher version. And I can't find any updated driver for
the card at:

It is written there that it supports 1.4 shaders (guess it is the
directx version, but it must supports OpenGL shaders too):

But are shader version number and OpenGL version number the same thing?

There's no link between them, it is just that you can now be sure that
your device supports shaders. Then it depends on the implementation of
the OpenGL drivers, I guess.
