Using Cg and OpenGL on old graphics card?

  • Follow


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.
