I''m using Visual C++ to develop an OGL application, and my machine has a Voodoo 3 video card, and is running Win2000. (I''ve installed the latest drivers from 3DFX for my card.) When running in debug mode, I get user breakpoints called from the OGL driver, and when the program ends. In the debug output, I get a load of messages from DirectX8''s debug drivers saying that memory has not been freed up. This leads me to belive that a) 3DFX''s OGL driver is a DirectX wrapper, and b) it''s not very well written. Has anyone else encountered this? Thanks, Al.

I know that some drivers uses DirectX but I think Matrox is the only one that has a true wrapper.
