In a seemingly impossible update, Call of Duty: Warzone has added 120 fps support when playing on PlayStation 5 through backward compatibility. Get ready for buttery smooth gunfights, all without having to download the entire thing again.

To implement PlayStation 5 exclusive upgrades, you have to release a PlayStation 5 updated version of the same game, such as with Marvel’s Avengers. This means reinstalling the lot. You can’t have one thing enabled on the PS5 but not the PS4, at least, that’s how it was said to work, hence Overwatch skipping out on higher fps updates and the like.

With that in mind, it’s certainly strange that Call of Duty: Warzone has pulled it off. If you’re on PS5, you can play at 120 fps, but you can’t on the PS4. Either Sony has sneakily enabled this ability in the backend or Activision has pulled off something magical. To get this working, head over to the console’s settings and set “Enable 120Hz” to automatic while also setting “Game Presets” to performance mode.

It’s possible that this was entirely accidental, although that doesn’t seem likely. At any rate, a native PS5 port is rumored to be launching alongside the next Call of Duty outing from Sledgehammer. It’ll be updating the engine once more, the same one that Cold War tweaked from Modern Warfare.

Despite Cold War modifying Modern Warfare’s engine slightly, with its own PS5 mode, Warzone continued to use the older variant with no next-gen port. This meant that there was some comical backward implementation of skins and what-not from Cold War, but with Sledgehammer’s new Call of Duty, that is allegedly set to change.

With that, we could see features like an FOV slider and faster load times as well as a performance mode that enables 120 fps from the menu rather than through fiddling with the PS5’s own settings. For now, though, the latest update has snuck in support, somehow.
