I'm pretty new to OpenGL programming, and now I'm following the tutorials made by NeHe, but I've got a problem: My computer has 2 videocards; a "standard" video card (with 2 MB memory), and a 3DFx voodoo2. With all these programs here, the program automatically sets my primary device as the displaydriver. How can I choose between diffirent videocards, so I can run all the programs like they should. (even while I'm rendering a single triangle and a quad to the screen, my framerate is about 4, 5 fps.) Can someone help me with this ? Edited by - lacsap on November 8, 2001 7:49:34 AM

Hmm, anyone already thought of creating a FAQ about this OpenGL forum ? This is one of those questions that are asked at least twice a week.

OK: the 3dfx OpenGL driver is not standard, to choose your Voodoo2 as the default OpenGL card you have to rename 3dfxvgl.dll to opengl32.dll, it will then be used for *all* OpenGL apps. If you want to use it for a single OGL app only, then copy 3dfxvgl.dll to the apps directory and rename it as above.
