It’s just a polished reshade and packet into a .zip file, although it makes the game look much… much better! Be aware that when loading the game, loading screen will get color bugged for a few seconds, but it’s the way it works… no can do there.
The installation process is quite easy, simply uncompress the zip file, and move the entire content of the folder “DeadEarth_reshade” to your game folder, and that’s it!
