Is there a 3Dfx based glQuake for Linux?
Yes. A Quake linuxquake v0.97 binary has been released based on Mesa with Glide. The Quake2 q2test binary for Linux and Voodoo Graphics ™ has been made available as well. A full Quake2 for Linux was released in January 1998, with linuxquake2-3.10. Dave “Zoid” Kirsch is the official maintainer of all Linux ports of Quake, Quakeworld, and Quake2, including all the recent Mesa based ports. Note that all Linux ports, including the Mesa based ones, are not officially supported by id Software. See ftp.idsoftware.com/idstuff/quake/unix/ for the latest releases.
