The distance in which things render (mainly outside after this past update) is too small. I know that the game is being optimized all of the time, but we need a way to keep the emersion. Instead of seeing bare/plane mountains in the backround, with some floating trees, you could maybe try and add a sort of fog effect (similar to the one you already have). Arma 3 or just cause 3 are both good examples. in arma 3 there is just a border of fog where things wont be visable or rendered which is a distance set by the user. But in just cause 3 you can see everything and it looks good. This is caused by a downgrade on textures/models that are far away and they gradually get better the closer you are, which is a system I think could be improved on in STN and work work marvellously if done coreectly, especially since the game is so pretty.
