The tech itself is pretty impressive including assets to build it etc. This was done by Unity on the unreal engine 4. But the sad fact is that its running at 720p because its a console game. What is the point of such photorealism if the hardware in this case the PS4 pro is its limitation? Its the reason why so many have backed star citizen in the end. Also the demo is in all likelihood not the actual final game graphics that the end used will receive but its still a good demo to watch and imagine the what could be aspect of it. As for star citizen, I dont expect this in the PU due to the poly count but might we expect this level of graphics in SQ42?
