coding help:.. how to select 3d cards

im trying to learn how to program OGL but but my primary card is too slow and all programs i run go very slowly. This is very annoying for me and i want to fix it. I have two cards. the primary is a sis6326 onboard card and is very slow. the other is a voodoo2 which will be more than enough to run the programs i am trying to make. How do you give an option to select which card to use to run an ogl program?! any help or links to sites that can help would be appreciated… thanks.

The place to ask this question is in one of the developers forum (OpenGL coding: beginners seems like the right one).

Regarding why it’s very slow on the 6326, it’s because this chip doesn’t have OpenGL drivers, so you’re getting software rendering.
