If the fog, especially around the town area, is too thick for your liking, there is a very good mod out there that lets you control this:  https://www.kingmods.net/en/fs25/mods/67155/fog-control

For using precision farming, you MUST have Thundr's Precision Farming Configurator in your mod folder.  This mod can be found here: https://thundrfs.itch.io/fs25-precision-farming-configurator

Some people have problems when continuing an existing save after updating. In those cases, you have to delete these (view here: https://ibb.co/C34Ysm0T) precisionFarming grles from your savegame folder so PF makes new proper sized ones. After resetting the PF layers, the game should run normally from then on out.
