Following the misconception that the Xbox Series X games would (and be required to) run at 60 FPS as a standard, Xbox Games Marketing Head, Aaron Greenberg, has clarified that it isn’t the case.
Long story short, Microsoft isn’t mandating game studios to develop their games to run standard at 60 FPS. In a statement to The Verge, Microsoft said, “It’s up to individual developers to determine how they leverage the power and speed of Xbox Series X.” Shortly Thereafter, Aaron Greenberg made a rebuttal tweet along the same lines, saying,
“Developers always have flexibility in how they use the power, so a standard or common 60 FPS is not a mandate.”
So, while the Series X is capable of running at 60 FPS and even 120 FPS without issue, game studios will be the one responsible for a game’s performance. If a studio doesn’t want to take advantage of what the Series X can do, they don’t have to. Of course, there’s a good chance that most AAA games will run as high as necessary or possible, as consoles finally have a chance to really compete with PC, which has been running games at 60 FPS (with or without mods) for a fair amount of time already.
