I tried compiling one of the opengl.org nehe tutorial, in my machine using the windows opengl library that comes with visual studio 5 and the result was sloow, about 3 fps, it was a lot slower than the win98 screensavers. Im using glut32, opengl32 I have 3dfxfl.dll in the windows dir, im compiling with msvc 5.00 My machine is a pentium 233 32 megs in ram with a banshee 3dfx card on it, (I saw the web page, and suposedly I have the full ICD ) please help! I really want to start using opengl but I simply CANT work at that speed!

Is Banshee Voodoo3( I don''t know much about 3dfx names)? Unless its voodoo3 it has a full OpenGL support now but It''s not an ICD. That means it doesn''t tie into the Microsoft Opengl32.dll and uses a different .dll that most professional stuff makes an exception for.

Somewhere on gamedev is an article with headers that will figure this out for you. I''m not sure where though.

Well, I think it actually is voodoo 2, not voodoo 3, however as I said, there is full compatibility acording to creative labs.
Thanks for the answer anyway, ill check if I can find the info in gamedev.

I already checked, but found nothing, is there anyone out there using the same system I do?

AFAIK Voodoo''s before the 3rd edition do not have full OpenGL ICD. So your windir/System/OpenGL32.dll is Microsoft''s software one.
You could try to backup OpenGL32 and rename 3dfxGL.dll to OpenGL32 but I''m not sure it will do because 3dfxGL is only a partial ICD.
Otherwise, try to catch 3dfxVGL.dll for your video card (with www.glsetup.com for example) and rename it to OpenGL32, it should be a more or less full ICD.
