View Full Version : HDR settings, Maximum Luminance issue

10-06-2018, 07:44 PM

I got issues with the HDR setting, Maximum Luminance.
It "resets" Maximum Luminance during gameplay to 603 Cd/m2 for some reason.
The odd part is that the default setting is: Maximum Luminance 800 / Paper White 120, and that only the Maximum Luminance is changed.
I can't see where it gets the value 603 from, as the HDR settings apparently are not stored directly in the config-file (ACOdyssey.ini).

I found a way to reproduce/force it to happen, by alt-tabbing out of game and in again, then the setting is set to 603.

I use windows 10, and only use HDR in games, not on the desktop. I tried enabling that and changing the settings available in Windows, but it does not seam to change anything ingame.

Update 1.0.3:
After the update, the setting, Maximum Luminance is changed to the default value of 800 Cd/m2, after tabbing out and in again.
Compared to 603 Cd/m2 with update < 1.0.3.

Thanks in advance.

Since the release 1.0.3, It's look like HDR is actually broken in this game,
it's look like a big wash too white glow, nothing to do with what I was seeing last week

I didn't change settings I was using 1000 / 250cd/m2, now if I use this settings, ocean is become pale blue washed white, no real hdr contrast
now my settings could be 800/100 to produce around the previous...

It feeling like a kind of fake HDR now, I tried different driver 411.70, 416.16 and 416.34 all showing same

I tried other game, there are still perfectly showing HDR.

I think I will go in my acronis backup, found the version of Wednesday, probably 1.0.2
