The shaders employed in this game are first rate though most folks - reasonably - are not thinking of shaders. They see it as lighting.
This game so impressed an old friend of mine, retired from the rather stressful and tedious business of making game, that he made a time-lapse video demonstrating its virtues.

I found this impressive but a bit....ummm.....highbrow for my tastes. But I agreed with him and posted my favorite demonstrations of the shaders used in ESO.
God help me, I love Dunmer gals....
