The horse was one of ESO's very first mounts and has since seen some updates. Yes, many other mounts have emerged in the meantime with better modeling and better animations. Smoother animations next to a horse making very "robotic" or jerky. A change should therefore see the light of day for the most classic mount that is the horse.
For those who want examples, the first version was: Sorrel Horse, Imperial Horse, Palomino Horse...
Version two has the same animation as its predecessor, but the modeling has been refined: Snow-Blanket Sorrel Horse, Silver Dawn Argent Charger, Holdbreaker Warhorse.
It seems that we have just moved on to the third version of the horse with the Akaviri Potentate Charger... Finally, I imagine that phase three has been brought into play recently and that of the Potentate may not be the one l 'having inaugurated. I come out of my cave on the question. : /
The changes in the animation skeleton are much more visible in pause than in running / walking.
No more static smile to show us their beautiful teeth ...
