The preset provides more natural lighting and color palette. It is meant to be used with Immersive Lighting mod. I made both OldGen and NextGen (DX12 only) version. The NextGen version's screenshots were taken with RayTracing on. However, the preset also looks good without it.
In order to achieve the visuals from the screenshots you'll also have to:
1. Install MrRox's Immersive Lighting.
2. Install KnightTec's BlitzFX (OldGen only).
3. Install FumioShwartz's Better Light Sources.
4. Install Boostin4kix Lina ScoutBr0's Next Generation LOD (OldGen only).
5. Install Atmospheric Nights mod (OldGen only). DOWNLOAD LINK BELOW.
6. Install shaedhen's Darker Nights upgraded to NextGen by teresatiger (NextGenOnly).
Installation:
1. Download and extract the preset.
2. OldGen: Paste the files into The Witcher 3's main directory/bin/x64.
NextGen: Paste the files into The Witcher 3's main directory/bin/x64_dx12.
3. Overwrite the files if asked.
RECOMMENDED SETTINGS:
Bloom - OFF
DOF - OFF
Sharpnening - LOW
