Including HDR or High Dynamic Range is common in video games, but now and then, a game is released without HDR support, and Atomic Heart is one of them. However, there is a way you can enable HDR in the game, you might need to do some research, but that is why this guide is here. Here is how to enable HDR in Atomic Heart.

Enable HDR In Atomic Heart

First, you need to find the Engine.ini file. Go to C:\Users\yourname\AppData\Local\AtomicHeart\Saved\Config\WindowsNoEditor. Right-click Engine.ini > properties > check Read-Only. Open the Engine.ini file in a notepad, add the following lines, and save the changes.






Now adding these lines won’t just magically make the HDR work; you need to input the correct values for “r.HDR.Display.OutputDevice” and “r.HDR.Display.ColorGamut” to enable HDR in Atomic Heart properly. The following explains what each value is for so you can easily input the current values.


  • 0 – sRGB (LDR) (default)
  • 1 – Rec709 (LDR)
  • 2 – Explicit gamma mapping (LDR)
  • 3 – ACES 1000-nit ST-2084 (Dolby PQ) (HDR)
  • 4 – ACES 2000-nit ST-2084 (Dolby PQ) (HDR)
  • 5 – ACES 2000-nit ST-2084 (Dolby PQ) (HDR)
  • 6 – ACES 2000-nit ST-2084 (Dolby PQ) (HDR)


  • 0 – Rec709 / sRGB, D65 (default)
  • 1 – DCI-P3, D65
  • 2 – Rec2020 / BT2020, D65
  • 3 – ACES, D60
  • 4 – ACEScg, D60
