This entire article is not only misinformative, but purely speculative. A game trailer is often the poorest indicator of how well a game will run on any hardware because to put it simply Trailers are frequently pre-rendered.

Likewise, a 60 FPS trailer could represent a game that struggles on average hardware.Trailer footage can support observations about graphics, art direction, and what appears on screen. It cannot, by itself, reliably support conclusions about real-world game performance. The fact that this article was even allowed to be posted without fact checking is mind blowing.
