I don't think what crytek was doing is the same thing. New builds of UE3 has stuff like indirect lighting as well, but it's not nearly as effective as this demo. I should do more research, but I was under the impression that those were still all just clever hacks. They weren't actually making all the calculations. I'm not that familiar with Crysis, but the video for Crysis 3 isn't even in the same ballpark. They've been hyping their next gen engine for a while, but it looks like mostly hype to me.
