After looking all the recent games being shown: the Order: 1886, Quantum Break, Ryse, InFamous: Second Son, and Uncharted 4- I think it's ridiculous to say any one looks factually better than the other.
Each game is trying different things with different techniques- and all look mesmerising in their own right.

It's obviously pretty early. Some of the areas looked like they lacked shadows, and I'm sure there is a ton more polish to come in- but even with that said- in my opininion is at the bleeding edge of technology.

Bravo Naughty Dog.
