Xengine (also known as XenEngine) is a third-party 
Source Engine branch using licenced code. It is a modified version of the 
Source 2013 Multiplayer engine branch with 
Team Fortress 2 additions, whose development was influenced by the limitations of the Source Engine. Although initially only CSM was planned, they gained much more knowledge while working on the engine, which allowed for more experimentation and improvements, eventually leading to the introduction of a completely new lighting system, and deferred lighting.
Features
- Engine
- Entity Limit and Displacement upgraded from 4k to 8k.
- Improved AI, whose behavior depends on the current difficulty level (some NPCs also support Main and Assault Behavior Trees from
aifolder). - Temp lights were swapped with new deferred lights.
- Gbuffer that allowed to add some modern difficult effects.
- Made from scratch Qt UI with ability to be customized and add new stuff with no limitations (old VGUI can be enabled with
-oldgameuilaunch parameter). - Using
Fast Approximate Anti-Aliasing (FXAA for short) instead of MultiSample Anti-Aliasing (MSAA) for anti-aliasing, which reduces performance and does not work correctly on Xengine's deferred lighting (unlike FXAA). - New and extended Post Processor.
- Native Linux support and OS based on it.
- Enhanced multiplayer with tonne of fixes for both client-side and server-side.
- Dynamic music system.
- Visuals
- 4Way blends with support for 4 bumpmaps and tri-planar mapping, enabling all the options from other material shaders.
- Cascaded Shadow Mapping with PCF-based soft shadows and viewmodel self-shadowing.
- Parallax Occlusion Mapping.
- Deferred lighting.
- Dynamic lighting system with PBR-based lighting and speculars.
- Light cookies for both new point light and new spot light, the last can be animated.
- Support for up to 2K dynamic lights per scene and all rendering features on secondary render targets (reflection/refraction, monitors, TV screens, etc.)
- Upgraded flashlight using new deferred lighting system.
- Godrays with disk for both sun and local lights, the last also can use Fancy godrays type.
- Screenspace Fog ("Xog"), that can be applied globally or locally using cuboid/ellipsoid volumes.
