So I improved the graphics a bit, pretty much everything.

No more tree lod popping, all lods increased: bushes, rocks, details. Absolutely nothing pops up anymore. Greatly increased grass distance. Shadows improved, also distance. clouds improved. fog optimized and improved. True sky activated. Better taa, sharpness enabled. Anisotopic filtering enabled 16x for better tecxtures. Brightness and color adjusted, no more fading. Better vision at night. Post process effects like motion blure, grain, and chrome aberration disabled. Screen space reflections improved. Improved water tessellation. Optimized Fog. Added dlss sharpness. Better Quality and optimized ambient Occlusion (Darker trees at the distance). Optimized lighting for Performance (+ 15 fps). Especially noticeable at sunrise and sunset.

To do this, proceed as follows:
Go to the following folder: C:/Users/Name/AppData/Local/VicingOyunu/Saved/Config/WindowsNoEditor and open the Engine.ini with a double click.
Now copy and paste the following (leave one line blank)::

Save and close.

If you don't see the AppData folder, you have to enable this in the advanced folder options in windows: show hidden folders and files.

For better Performance activate dlss.

But I deactivated it because of the dlss ghosting. I tried to fix it with different settings (increase sharpening), but unfortunately without success. The dlss version would have to be updated to a higher one by the developers (via plugin), then the problem would be better. However, with the updated guide I have very good fps (rtx 3070, 1440p) and can play at very high fps without dlss.

If you play with dlss, it is advisable to increase the sharpness:
r.Tonemapper.Sharpen= to 0.70 or 1.0

Color and brightness optimization of the system:

Adjust ingame gamma 3 steps to left (down).

Nvidia: Go to digital color enhancement (desktop color setting) and select a value between 60-80%.

Go to Change Resolution, scroll down and select: Nvidia Color Setting. Dynamic Output Range: Full. Color format: RGB.

Have fun!
