“DarkPlaces is a Quake modification I have built over the course of 6 years on and off experimenting, it got somewhat of an overhaul when the Quake engine source code was released, and I began developing a custom OpenGL-only engine for it and other mods, which supports Windows WGL and Linux GLX, and has greatly improved graphics and image quality.”
On L.G.C. EP08 we bring Quake 1 kicking and screaming into 2010. This how-to was done with Ubuntu 10.10 but could be easily adapted for other distributions.
A few things. The HighRes mod takes about 12sec to load on my X2 2.8. After that you might want to cut on texture compression (it was choppy on my 9500 1gb) for higher frame rates. The best part of playing with Q1 was finding the Q1 DM community is still active. Now get off my lawn ;)
