This looks like it was rendered in a 3D engine. Imagine Dragonborn visiting the Grey Beards in High Hrothgar just on the other side of the scenery. Or if you feel goofy, you can see how some Skooma-stimulated player tries to run to the top at all costs.
Yet this real mountains as seen from Hohenwerfen castle in Austria. Hohenwerfen sits on a steep mountain over the town of Werfen with its train connection to Salzburg. It is an ideal daytrip from Salzburg or even from Munich or Vienna. Even the trip itself will provide magnificent views, especially if you come from the lowland.
