PlayDevil has checked out the first season of The Walking Dead on Xbox One:
Here is a snippet:
"The graphics get a bump to 1080p, but the extra clarity is a mixed bag. In some situations, the extra crispness brings the world to life, but in others it points out the lack of aliasing, some pretty rough textures and general lack of background detail; making the game look rather ugly. And whilst the general engine performance is significantly better than on the old consoles, there are still frame-rate hitches and drops here and there."
