Xengine Xengine (also known as XenEngine) is a third-party Source Source Engine branch using licenced code. It is a modified version of the Source 2013 Multiplayer Source 2013 Multiplayer engine branch with Team Fortress 2 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 ai folder).
    • 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 -oldgameui launch parameter).
    • Using Wikipedia icon Fast Approximate Anti-Aliasing (FXAA for short) instead of Wikipedia icon MultiSample Anti-Aliasing (MSAA), 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.
