Promotional screenshot of Apex Legends, which runs on a heavily modified version of the Source Engine called Titanfall engine branch, featuring DirectX (Direct3D) 11, detailed models and better graphics, plus increased the engine limit, allowing maps to be larger.

The Titanfall engine branch is a third-party Source branch developed by Respawn Entertainment using licensed Source Engine code from Valve. 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 running on consoles at 60FPS. This engine branch is still in active development.

Features

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

Native DirectX 11 (dxlevel 110) and DirectX 12 (dxlevel 120) (only in ) renderer

DirectX 11 (which includes Direct3D 11 renderer) is now supported, previous version has been dropped. DirectX 12 is also supported in Apex Legends when launched with -eac_launcher_settings SettingsDX12.json launch option.

DirectX 12 (which includes Direct3D 12 renderer) requires Windows 10 or 11 in order to work.

Confirm:Does Windows 7 supports Apex Legends running in DX12 mode after 2019 OS update?

New rendering system with Physically Based Rendering

64-bit support

Full support for 64-bit. 32-bit are not supported on this branch.

New netcode

Customized version of BSP and VPK

Audio system improvements

Better HDR Rendering

(only in PlayStation 5), unofficial support on PC is possible through Windows 11's Auto HDR feature.

Custom in-house Sound System
