I would recommend to use the ReShade 4.9.1 however I included the dll so there's nothing to worry about
For more information about the ReShade you may visit the:
https://reshade.me


Installation, You may extract the file/s in the game directory

And load the preset through reshade menu 



The preset contains the:
-Colour Correction
-Adaptive Tonemap (UE4 Preset)
-Vibrance
-Adaptive Fog
-Improved Ambient Occlusion 
-Adaptive Sharpen (AMD CAS) 

Lite Version
-Colour Correction
-Adaptive Tonemap (UE4 Preset)
-Vibrance
-Sharpen


If there's some shadow bugs or some sort of stuff related to shadow, I would suggest to turn off the In game Ambient Occlusion in the settings, if the issue is still persist, you may tweak and untoggle the MXAO



Since there is known issue to the latest ReShade (5.0.2):
-Incompatibilities of the LUT packs, so the shader would be messed up. And I would take care of it soon.


Installation, You may extract the file/s in the game directory

Or you may load the preset through reshade menu



This is my first ReShade mod to release so I'm still learning.
