Are you setting the resolution on the command line/shortcut itself? (Quake.exe -width 1024 -height 1280?)

Tried that on the desktop shortcut, no dice. Tried moving the opengl32.dll out of the quake dir and using the nglide app also no dice. Do I need to delete all the graphics dll's out of the quake directory?

As said in the other thread, do not use nglide. The CD image is included with the gog release.

Delete the opengl32.dll, that's just for old voodoo drivers that didn't have full opengl support yet.
glquake should run just fine on your gf3 but you may want to use something like fitzquake 0.75 (newer doesn't work for me on win98) to get the visual effects missing in glquake. That is what i'm using on my 98 machine with a gf4 ti.

To set up fitzquake you simply download the .exe, drop it in the quake directory and set the resolution via a shortcut just like regular old glquake. The same procedure goes for most source ports.

^^ Yup, burn the CD image from the GOG Quake release. It's a full WinQuake installation.

Then install from that CD. It will ask you:

- Do you want GLQuake? Say yes.
Then:
- Do you have a 3dfx card? Say no.

The game should then work using GLQuake, but an older version.

Get the latest version, copy the files into the Quake folder, create a shortcut with the resolution settings and you're good to go.
