Ghost of Tsushima - HDR Optimized Settings (Patreon)

The game DOES USE/APPLY Playstation HDR Calibration app settings but not PC HDR Calibration ones.

It has a good HDR implementation and is one of the few games actually leveraging system-wide HDR settings on Playstation.

It also offers a separate Brightness control which can improve shadow details:

Set the BRIGHTNESS slider to 60 to improve shadow details (which can be a bit crushed by default) and have a more natural look.

FOR THE PC VERSION:

You need to setup HDR directly in-game with additional sliders:

If you have an LG OLED and:

> you're using Dynamic Tone Mapping or Dynamic Contrast:

Set HDR MAX LUMINANCE slider to: 1.500 (nits; Max)

Set HDR PAPER WHITE slider to: 200 (nits)

> you're using HGIG:

Set HDR MAX LUMINANCE slider to: 800 (nits) or 1.000 (for G2/C4) or 1.500 (for G3/G4)

Set HDR PAPER WHITE slider to: 200 (nits) or 276 (for G3/G4)

If you don't have an LG OLED and:

> you don't have an HGIG option:

Leave HDR MAX LUMINANCE slider to: 1.000 (nits; Default);

Set HDR PAPER WHITE slider to: 200 (nits)

> you're using HGIG:

Set HDR MAX LUMINANCE slider to the corresponding real Peak HDR Luminance of your TV in "nits"

Set HDR PAPER WHITE slider to: 200 (nits)

In all cases, set the BRIGHTNESS slider to 60 to improve shadow details (which can be a bit crushed by default) and have a more natural look.
