OpenMW Screenshots, running on a 2 year old Android phone.
Full speed.
(Screenshots of OpenMW are rather sparse, because the devs made an agreement with Bethesda not to post screens of MW running in their engine rewrite.
Anywhere on their site. Even in the forums.
(Linking is ok.))
Also - as correctly said by AnnOying - a port would have quite a few hurdles - one being the project itself not being 1.0, another one still being the UI - which (in the PC version) still is highly complex - and difficult to port in a meaningful way to console. (You raise font size for text (heavily text based game), you reduce screenspace for the 5-7 different menus that should be on screen once you hit menu...
Stuff like that really is hard to fix without touching (rewriting) the UI itself.)
Also - its still the best "modern style" Bethesda RPG by a large margin. (Attention to detail is about 3x higher than in Skyrim.
Story/Worldbuilding is much better.) And yes - its absolutely unplayable on an android phone (UI is too complex for a touch interface).
Strolling around, like while taking the pictures is fine - but actually playing it - no chance.
