Yea, it's definitely CG. It looked less CG to me on the standard def broadcast likely because I wasn't seeing it at this level of quality. It's actually making me wonder just how much more amazing that in-game footage must look In proper direct feed quality.
Its not really CG.
It does have normal Marius model, except for hairs on helmet that are different than in any other game video or cryengine renderer from MP Trailer.
Also there are ton of shader aliasing. Fire is pretty standard for games [just 2D sprite], smoke in the background is also made from sprites. Shadows on soldier at distant stairs have normal resolution.

So, it looks better than Xbone in-game footage and it looks worse than CryEngine render from from MP Trailer. Strange, its also much closer to real-time footage.
