HDR analysis and setup guide for S.T.A.L.K.E.R 2. It's for the big update 2.0 the game got in Aug 2026.
I have only tested this on PC, but it's most likely the same for consoles.
PC - RenoDX:
PC gamers should use the RenoDX HDR mod for Unreal Engine in its extended version. I have an article that explains how to install it. Picture 1 is using RenoDX UE Extended version.
In-game HDR (consoles):
The in-game HDR seams to be the standard Unreal Engine 5 HDR solution. It means more saturated colors and darker shadows. It's also what we see when we comparre picture 1 and 2, where picture 1 is the RenoDX HDR mod and picture 2 is default in-game HDR. Both are setup for 1000 nits peak brightness.
In picture 3 and 4 you can see the in-game sliders. Both the HDR sliders and the SDR sliders effects the in-game HDR output. I don't like giving HDR sliders values like -6 and 25. What do they mean ??? It's also confusing that the brightness slider (not the HDR brightness slider) effects peak brightness. It's not exactly an intuitive HDR setup menu.
I recommend to change the in-game saturation slider from 60% to 40% to lower the saturation.
I also recommend to increase the HDR black point slider from -4 to -1.
I have tested these settings in several different scenes in the game, and tried to match it to RenoDX. But utimately it's personal preference. Try it out. I think it looks better than default.
The game outputs a max of 1000 nits. It's adjusted on the HDR white point slider. I have tested that the game will output the peak brightness you set on that slider. So if your display can do 800 nits, then set that slider to 800 nits.
Thats the only adjustments I recommend to make to the in-game sliders in a dark room. If you want an overall brighter picture for a bright room than increase the HDR brightness slider.
1000+ nits peak brightness:
If you have a display capable of higher than 1000 nits, then the game can output higher than 1000 nits if you increase the brightness slider (the SDR slider). At 60% the game will output close to 1500 nits for instance. Doing so will increase everything including midtones and black levels. You will than have to change the HDR black point and white point sliders to bring that back. It's not something I have used time on doing for various peak brightness levels above 1000 nits.
