Game Version number: 1.2.0.92
Modded?: No
The 1.2.0.92 changelog includes the following item:

Changed: HDR Darkness and brightness limits, target brightness, and shutter limits by weather cycle

However, the game does not appear to run natively in HDR (on PC, at any rate), nor is there an HDR on/off option in the graphics settings. HDR can be forced using Windows 11's builtin Auto-HDR functionality (or by other methods), but this is not ideal.

Is full HDR support in WIndows a planned feature?
