Why does ATS look better graphically than ETS2?

[brizzcoo]

ATS is being made from scratch with "newer" technology, keep in mind that apart from 3 default states, all other map content is DLC were ETS2 still have vast territories that are seriously outdated even DLC`s key example is Going East which looks like crap they put together ages ago only to make some money on it knowing that a good chunk of players i.e. customers came from Eastern Europe. Other than that ETS2 is really really old and changes in an archaic game engine wont do much.
