The Dark Mod went standalone. I bet it still has issues but at least they are free from Doom 3 limitations and this means they don't have their hands tied anymore for further improvements.

In addition to going standalone, the following improvements have been made:
AI Improvements: There have been lots of additions and fixes to AI behaviour; characters will now greet each other more regularly, and will properly call for help when they’re in trouble. Guards can now hear slightly better, and we have included a new AI Vision slider to the menu, so the player can adjust how sensitive they want AI vision to be. Characters react to bodies in more varied ways now. A bug that made AI very easy to kill has been fixed. Archers will draw melee weapons if the player gets too close. Guards will turn towards doors that open unexpectedly. There are new vocals for specific situations, like when guards are getting shot at and can’t see their opponent. Searching behaviour has been improved. Plenty of old bugs, like the one where AI would sometimes attack with an empty fist, have been fixed.
New Gameplay: AI can now hear collapsing bodies, especially if the body is wearing plate mail and falls on a hard surface. No longer will a guard stand oblivious while his friend collapses to the ground two feet behind him. The player will have to give some thought to where they take down opponents if there are other guards in the area.
Audio Improvements: In addition to replacing dozens of Doom3 sounds, two new vocal sets have been added to the game. Footstep sounds have been improved. Big changes have been made to the sound propagation system that will allow mappers a lot more control over how players hear sound; for example, mappers can now make doors block different amounts of sound depending on their thickness, or can control how much sound passes through windows or small holes.
Graphical Improvements: You should notice a number of improvements to some character models, especially the skeleton, townsfolk, and beggar characters. Arrows will now leave blood-stains.
There have been plenty of other bug-fixes, like removing the ability to hide in the shadow of an object you’re carrying (no more sneaking under a crate umbrella). See the full change-log here.
