You just completely ignored my post and replied to some imaginary one.
Look clearly at the message at the beginning of this trailer.

After Lord Error pointed out the image quality in this trailer is perfect in the way only downsampled material looks, I'm more than 100% sure this video was not running in real-time exactly as is. That's why ND keeps saying "in-engine", and never "running in real-time." It's not high-end, outsourced CGI, it's probably using assets that will look teh same or close to in-game assets, but it's not really real time.
