- Did you see the dragon parts right, like where the user moves across hundred of cars, did you see that right?
- Did you see all the elements in the flying part in the desert, does that look like a small area to you honestly?
- Did you pay any attention to the element in the back and how they are rendered without any loss of quality?
Those were small segments because the whole point of the video is showing how fast they can change everything. If they spent more then 10 seconds in any of those scenes people like you would be all over here saying that they were loading the things in the background...
