Difference between revisions of "List of Unreal Engine 4-5 games where HDR can be forced"

Revision as of 12:54, 26 November 2023

Unreal Engine 4 and Unreal Engine 5 have native HDR output that can be forced in many newer games with mixed results.

Earlier versions of Unreal Engine 4 required running in Exclusive Fullscreen (FSE) in order for this to work, while newer versions supports it for windowed modes as well, though some more recent versions have broken HDR in DirectX 12,^{[citation needed]} requiring the use of -dx11 launch argument to run games in DirectX 11.^{[Note 1]}

General information

See the official engine documentation for more details.

See High dynamic range (HDR) for more information about HDR.

Instructions

Enable native HDR output

For DirectX 12-only titles where forced HDR output is only possible using DirectX 11, use the -dx11 command line argument to force it to run in DirectX 11 mode.^{[Note 1]}
Using this guide on the UE4 engine page, change Engine.ini to include these lines:

[SystemSettings]
r.AllowHDR=1
r.HDR.EnableHDROutput=1
r.HDR.Display.OutputDevice=5
r.HDR.Display.ColorGamut=2

Optionally you can add these lines to boost the UI brightness. This might make the UI integrate better with HDR.

r.HDR.UI.CompositeMode=1
r.HDR.UI.Level=1.5

Supported games

The below is an attempt to list all known titles where Unreal Engine 4 and 5's native HDR output support can be forced.

Name	Render API	Notes
Blacktail	D3D11
Ghostrunner
Sackboy: A Big Adventure	D3D11	Raytracing and DLSS no longer work. Toggle fullscreen twice to fix blackscreen. Game brightness toggle no longer functions.
System Shock (2023)	D3D11	Results in increased dynamic range but UI is washed out, UI boosting may help.

Notes

↑ ^1.0 ^1.1 Running a game in D3D11 may not be officially supported and may experience additional unexpected issues unrelated to HDR.
