I call it fake for two reasons.
The first reason it took a lot of tries because they got a good run.
The second reason is they used the NVidia Software when they had no intention of using that.
If anyone did a serious investigation into it I don't doubt that there would be enough evidence to say that they committed fraud.
And they presented the video in a dishonest manner by not disclosing any of that at the time thus giving the impression they were much closer at the time than they actually were.
