I have an AMD K6-2 or K6-3 processor. Why can I run Quake2 using the 3DNow OpenGL miniport?
The Quake 3.20 miniport only supports Voodoo2. Full Voodoo3 support will have to wait until AMD releases an updated version of the miniport. There is a hack to make the existing 3DNow miniport work with Voodoo3: 1) Install the Quake2 3DNow miniport if you haven’t already. You can find a link to it in my Files Section. 2) Rename the file in your \QUAKE2 folder called 3DFXGL.DLL to OPENGL32.DLL 3) Go to the Quake2 Video Menu and select “3DNow OpenGL” as the video driver.
