This clip, which is masquerading as a Crysis 3 trailer but is really a showreel for the game's engine, is beautiful. It claims to be running in real-time, and to have been captured from Crysis 3 the game, not Crysis 3 the tech demo.
Unless it's a clip full of lies, this would have to be be the PC version of the game. Making me feel slightly uneasy about the state of my current rig.
Whether the top secret toad tech makes it to the console versions of Crysis 3, we'll just have to wait and see.
