I'm not understanding why some of you guys can't tell offline rendering from videogame cutscenes. It's so jarring it's so easy to tell. That video was mostly rendered with an offline render and the gameplay snippets are significantly "gamey" looking.
One good tell-tale sign is just by looking at hair rendering. There is no way that ANY GPU can render fur like this:
There is self-shadowing everywhere. The grass looks completely accurate and self-shadowed to give thickness. The DOF is astounding both front and back. The eyes on the creatures are completely reflecting using ray-tracing. There are no aliasing artifacts anywhere.
When have you ever seen FX emit lighting and shadowing in a videogame cutscene where every particle is a light source. And then see the subsurface scattering on the skin light up like that?
Gameplay:
All the shadowing is gone. The motion blur gives artifacts, the tree's leaves in the distance are shaded flat, the character lost her SSS. The little furry things have lost their hair, tree branches on the walls don't cast ambient occlusion, etc.. etc.. etc..
