I do not think that this has already been explicitly requested in a thread in the "wishlist" part : I want S397 to integrate into the graphics engine a foggy effect, with a "haze" that could sometimes take the form of that in PC2. This is a "mist" in which one really gets in while driving (don't know which synonym is appropriate). It could be more frequent early in the morning for example. (see Project Cars 2). Another feature that would be particularly suitable for the Nordschliefe ..............
