I stopped the video very quickly. The comparison is garbage. Real gameplay is compared with a trailer here. Whoever compares something like this must have been living under a rock for years and has absolutely no idea about video games and how marketing works.
The beginning of the video showed a nice example of the environment between the then and now. Certainly a difference with lack of pop-ins and better lighting. If you want to see only gameplay, watch the video from 1:40 onward.
