While it is an outstanding example of a fork on the Doom engine (the game Hypertension Harmony of Darkness being the best example of what the engine can do), Hyper3DGE is better suited for mod makers, specially those that want more 3D stuff on their mods.
However it is still a very young engine, it would be pointless to add it to the pandora yet as the onlly games (yes games, not a mods) that will properlly use the engine are Hypertension and SLAVE, plus they were the main reason to create the Hyper3DGE engine and for now they are exclusive to the Dreamcast.
New build on the repo. With quite some changes.
The biggest on is the OpenAL Sound Code used by ZDoom, GZDoom and Zandronum. Initialy, this code used GStreamer for OGG & MP3. While that worked, it was heavy and introduced weird micro freeze when loading sound (like in BrutalDoom where it was really visible).
The new code doesn't use GStreamer anymore, but simple mpg123 and libsndfile, making it much faster and removing mostly all micro freeze when sound are loaded/played. So yeah, BrutalDoom does play better now.
In the same time, I have updated Zandronum to latest version (so it's now some beta 3.0) and also quickly added Gamma support to Edge that didn't supported it in earlier build (using pandora gamma script).
New faster and lighter Sound code for (G)ZDoom and Zandronum
