ZDoomGL
From ZDoom Wiki
ZDoomGL is an OpenGL port of ZDoom written by Tim "Timmie" Stump (an earlier version was written by Michaël "Kokak" Ryssen). It is no longer maintained. Timmie started working on a complete rewrite in 2006, but development stalled and the project was ultimately abandoned. It is advised to use GZDoom instead.
