For me the trees arent render very far away at least not as much as the building.
I have a 10900k with a 4080S with everything crank to the max in the ingame setting.
For exemple, the road in the front of the dealership i can see the building on the farm by land 153 but there is no trees rendered
Edit: I have not modify the rendering distance in the XML i'm using the base game distance.
