We also should probably mention that the video is of course not how the game looks in FHD, since it has to be compressed in order to a reasonable size. The actual game in the screen will look way better in terms of resolution. It's an obvious thing, but one worth remembering when we have 4K images to compare with.
Hmm looks like native 1080p on my screen... It's still a 5GB uncompressed video :]
Regardless, I just hope the game doesn't end up looking like the PAX at Ultra, ... this just looks so bad
