well. yes i suppose. i've always assumed that was the point of the openGL library. but i'm just curious. i mean like i use a geforce 3. sometimes i get the impression there may be something one could do to a gl app to take advantage of an individual chipset.

For chip specific features, use extensions. This has already been beaten to death, but anyway
*get the appropriate headers for your 3d chip (nvidia.com might be a good start)
*at runtime get the list of supported extensions (extension string)
*import the extension functions. On Win32, use GetProcAddress(blabla)
*fire away
*make sure you have a fallback path that works if the extensions are notsupported

That's because you can find answers to questions like this in the OpenGL FAQ (http://www.opengl.org/developers/faqs/technical.html)
