Marvel's Guardian of the Galaxy - HDR Optimized Settings (Patreon)

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

The game has a fairly good HDR implementation with an actual Peak HDR Luminance slider (in numerical values but not in "nits") which can go up to 2.000 nits and also a regular Brightness/Gamma slider.

If you have an LG OLED and:

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

Set Maximum HDR Luminance slider to: 1.00 (which is around 2.000 nits);

> you're using HGIG:

Set Maximum HDR Luminance slider to: 0.30 (which is around 800 nits) or 45 (for G2) or 70 (for G3).

If you don't have an LG OLED and:

> you don't have an HGIG option:

Set Maximum HDR Luminance slider to: 0.45 (which is around 1.000 nits);

> you're using HGIG:

Set Maximum HDR Luminance slider to one of those values and the corresponding real Peak HDR Luminance of your TV in "nits":

In all cases, leave the regular "Brigthness" slider to 0.50 as it already represent a correct/balance exposure and gamma.
