OpenGL Driver Installation
Setting up OpenGL on any 3dfx card is a bit of a problem due to the mess
that 3dfx has made regarding OpenGL drivers. There are now 3 different
type of OpenGL drivers which can be used on a Voodoo 2 for GL Doom Legacy,
the 2 OpenGL ICDs, the Mini-GL, or Mesa, which is a freeware OpenGL equivalent
that just happens to be compatible with it.
By far the best way to run the latest version, beta-4, of GL Doom Legacy
is to use the Mini-GL, as it provides the fastest performance. For a Voodoo2
based card the latest Mini-GL version is 1.47, which can be downloaded
from here. This will
download a set of MiniGLs for lots of GL based games, e.g. Quake, Quake2,
Half-Life. Tell the installer to just extract the files and not to install
them, then goto the 'Quake' directory it creates where you extracted the
files, and copy the opengl32.dll from there into your GL Doom Legacy directory.
You will also need the latest Voodoo 2 drivers, which can be downloaded
from here. Just extract
these into a temporary directory and follow the instructions included.
FAQ
I haven't encountered any other problems with the Voodoo 2, but if you
find any specific to the Voodoo2 then mail me.
Tweaks
These are just the
startup commands which can be placed in your 'autoexec.bat' file to increase
performance.
