Graphics Settings
Just like most other Unreal Engine games, there aren't too many graphics settings. You can set each available setting to "Low", "Medium", "High", or "Very High".
What I really miss is an option to adjust field of view. This can be achieved by editing localappdata\HellbladeGame\Saved\Config\WindowsNoEditor\Engine.ini and adding:
[/script/engine.localplayer]
AspectRatioAxisConstraint=AspectRatio_MaintainYFOV
The depth of field and chomatic abberation effects can be disabled by putting
[SystemSettings]
r.DepthOfFieldQuality=0
r.SceneColorFringeQuality=0
r.OneFrameThreadLag=0
r.MaxAnisotropy=16
into the same engine.ini file.
