Maybe I was spoiled by learning OpenGL on an SGI, but I''m having problems writing win32 OpenGL code: everything works fine, but runs very slowly (because it is in software rendering mode). I would like to know how to enable hardware OpenGL acceleration for Win32 programs using 3dfx graphics cards (specifically, the Banshee, Voodoo3, and Voodoo 5 cards). In other words, what exactly would I need to link to the code, and what lines of code would I need to add, to have... say NeHe lesson #6 (or any other program) run in hardware accelerated mode in Windows NT with my Voodoo 3 graphics card? I am only interested in hardware-accelerated OpenGL, NOT glide. Thanks in advance for the help.

Thanks - you are correct. I copied the 3dfxOGL.dll file to OPENGL32.DLL and it worked (mostly). Still occasional glitches probably resulting from using an old .dll file for the Banshee graphics card.

You could also just put the your 3dfxogl.dll into your program directory and then just rename it to opengl32.dll. That way you''ll get hardware accleration. -DarkHacker

I thought you could choose which output device to use with SetPixelFormat(). I haven''t gotten around to trying it yet, but this is what I was told.
