It is a heavily modified version of the Portal 2 engine branch[1] that adds many huge modifications and improvements that bring Source close to modern standards while keeping the game consoles run the game well optimized at 60FPS. This engine branch is still in active development.


Todo: List all of the features of this modified engine.

DirectX 11 is now supported, previous version has been dropped. DirectX 12 is also supported in Apex Legends Apex Legends when launched with -eac_launcher_settings SettingsDX12.json launch option.
This would makes games requiring atleast Windows Vista SP2 or 7 to play.

A new audio system called Speex[confirm] has been used for Titanfall Titanfall, Wwise is also used in Titanfall Titanfall.
Miles Sound System (for Titanfall 2 Titanfall 2 and Apex Legends Apex Legends) has been updated to properly support 7.1 surround on modern systems and better DSP effects.
Better HDR Rendering
Custom in-house Sound System
Modern console support (PlayStation 4 PlayStation 4, PlayStation 5 PlayStation 5, Nintendo Switch Nintendo Switch, Xbox One Xbox One and Xbox Series X|S Xbox Series X|S)
Of little use to modders, needless to say!
