Hellblade: Senua's Sacrifice - HDR Optimized Settings (Patreon)

The game is NOT using/applying Xbox/Playstation HDR Calibration app settings.

Measured Peak HDR Brightness of the game will not exceed 1.000 nits and there is no way to control/modify it.

For this reason it is suggested to use Dynamic Tone Mapping in order to offset potential highlights clipping and lost detail in bright areas.

The game also provides a regular Brightness/Gamma slider:

but you can leave it at Default as it seems to not have any effect in HDR.
