Performance is significantly better on Microsoft’s console.
It seems Infinity Ward have sneakily added in 120 FPS support to the free-to-play battle royale shooter Call of Duty: Warzone on Xbox Series X, without much fanfare. As Digital Foundry points out, the game targets 120 FPS on the console, and generally stays in the 100-120 frames per second range.
What’s interesting, however, is that the same update hasn’t been applied to the game on the PS5, where the shooter hits a maximum of 60 FPS even in performance mode. That’s probably down to how the PS5 handles backward compatibility. Since Warzone is technically a PS4 game, Infinity Ward would most likely have to develop a native PS5 port of the game to add 120 FPS support.
This isn’t the first game that’s had this issue. Rocket League will support 120 FPS on Xbox Series X/S, but not on PS5, with the developers stating that the console’s backward compatibility toolset is to blame. Meanwhile, Star Wars; Squadrons, too, has similar disparities across PlayStation and Xbox.
