I improved some things on the graphics like:
Completely fixed bushes and trees popping up, increased grass distance significantly. True sky enabled, enhanced clouds. Also adjusted the color of the sky, more blue now. Optimized shadows, removed fading. Color adjustments and brightness adjusted. Removed fades. Fog density reduced. Lod distance increased and optimized. Texture streaming and performance optimized. Better anti aliasing. Ui scale set to 75%.

What you have to do:
Go to the following folder on your PC:

C:/Users/Name/AppData/Local/Ashen/Saved/Config/WindowsNoEditor

Now open the engine file and add the following:

Save and close it.

If you don't see the AppData folder, you have to go to advanced options in windows, folder options: show hidden folders; activate.

Have fun with the better Graphics.
