Framerates like that are quite possible in GLQuake, but people usually mess
around a lot with the gl variables in the Quake console and similar settings
on the 3Dfx card - as well as run in 512x384..
Can't see the point though since it's not worth the extra fps because you've
disabled the features.. you can't even (likely) see the extra frames anyway,
so you are 'degrading' the game :P
Anyway, enough drivelling from me here about Quake.. 'tis wrong group
anyways :)
