Alan Poster has released an interesting mod for Days Gone that aims to improve its graphics. Poster has implemented a number of Unreal Engine 4 tweaks that aim to enhance several effects like Ambient Occlusion and reflections.
Going into more details, this mod improves reflections, ambient occlusion, shadows, and LODs. Furthermore, it enhances the game’s God Rays and tone mapping. Not only that, but this mod improves the game’s volumetric fog, puddle reflections, and improves color grading.
What’s also interesting here is that the modder claims that this mod reduces the game’s stuttering issues. I haven’t personally tested it, so I cannot confirm (nor deny) it.
You can download the mod from here. You can also find below some screenshots that showcase the improved visuals. Unfortunately, though, the modder did not release any before/after screenshots.
