We're starting to get a sense of why PlayStation 5 users are unlikely to see PlayStation 4 games run at 120 frames per second on Sony's new console - despite the PS5 being perfectly capable of doing it.
Last week, I reported on how Infinity Ward had quietly updated Call of Duty: Warzone to run at 120fps on Xbox Series X, but not on PS5.
Warzone, which comes up as a PS4 app when it's downloaded on PS5, does not boot in 120Hz, and there are no in-game menu functions to enable it. Activision declined to comment when contacted by Eurogamer, leaving us to assume the reason for this difference had to do with the way Sony handles backwards compatibility. At the time, I speculated that Infinity Ward would have to create a full PS5 port of Warzone in order to enable 120fps on the console.
