Hello everybody! I´m quite new to OpenGL programming and I am studying these really great turorials. Now, I have a problem, which was posted here couple of days ago. I have a S3 Virge card and a Voodoo2 as well in my computer. I want to use these examples here to make use of my Voodoo2 board, since the other runs at 3 frames per hour In this board, someone adviced to copy the 3dfxvgl.dll into the application´s directory and rename it to opengl32.dll. I tried this, too but all I get is a general protection fault error in Glide3x.dll. Does anyone know, why I get this error? Hope, someone can help me out here because I am really stuck here! Thanks, Joerg!
