OK, I have finally found the problem that causes my 3D engine to crash on 3dfx cards! Whenever it tries to clip the near-clipping plane, it crashes out with 3dfxogl.dll giving an exception error of 10H. This is all fine and dandy, but WTF does 10H mean? The 3dfx site is dead and nobody seems to know? The application is OpenGL because nobody has the Glide3 SDK anymore so I [b]CAN'T[/b] program an option for Glide into my engine! Can somebody help me figure out why the near-clipping plane in OpenGL crashes on 3dfx cards? Thanks a ton!
