DirectQ is a Quake Source port by MhQuake and Attacue, Unlike other quake engines DirectQ uses DirectX for rendering instead of OpenGL. This results in a very fast engine being able to run even on older systems with the latest DirectX.

Quake start in DirectQ with enhancement paks.
DirectQ ceased development in 2014 due to unknown reasons. The latest version is 1.9.2, there were plans for a 2.0 version using DirectX 11 and a Quake 2 version named DirectQ II.
The engine's spiritual sucessor is the MarkV engine.

Custom music[]
DirectQ supports custom music similarly to Quakespasm or Darkplaces, Ogg support needs the required codecs.
First create a directory under the ID1 folder named music.
Secondly add the music files here. They can be either .mp3 or .ogg
Name them accordingly (ex. Track02.mp3). There's no Track01.mp3 since quake used Track01 for data. Do this for all your other music files. Name them up to Track11.mp3
Quake's soundtrack can be downloaded here [1].
