Hi, All.

I have a problem. I have a possibility that my program will trying to run on computer with to different Video Card that both support OpenGL (for example GeForce and Voodoo 3, or GeForce and Riva TNT). How can I select firts or second Card for rendering? I think windows always try to use default OpenGL, but I want to select and use renderer by myself not by windows. Please help.

Yours, Mad Max.

P.S. If someone have source or know where I can get it, please write.

I dont think thats possible!. I know its possible for direct3d, in OpenGL (wgl I guess) there are no functions for that. I dont know of any anyway.

And who's fault is that!?!!...

But if its a Voodoo2 (or 1) and another card I guess you could. By loading the dlls dynamically..
