Sure, I Guess
It's alright but it doesn't really work very well. Fairly bare-bones and has a general lack of polish. AD barely works on it.
It was vaguely popular in the mid 00's. FitzQuake has almost completely superceded it though.
Just Got Curious
because I had heard virtually nothing about it before. I don't know if it is still under active development or abandoned.
At first glance, there is little right now that would set it apart from other vanilla-like ports such as Mark V or Quakespasm. Besides the fact I couldn't get it working properly with widescreen resolutions.
TyrQuake... was the engine Oz and I made our hacks with for a while :) Alongside Darkplaces, it was the best Linux Q1 engine - until Kristian ported Fitzquake to SDL.
As Linux user I found recent use in TyrQuake for having a traditional software renderer, but with much raised engine limits. It certainly seems to be a "mostly vanilla" engine, with welcome updates here and there. I see that it even got some neat updates in git, especially support for ALSA sound support.
