Call of Duty: Warzone has become the first PlayStation 4 backwards compatible game to support 120hz on PlayStation 5.
Rocket League is in a similar boat to Warzone: the hugely popular football driving game was updated to run at 120fps on Xbox Series X, but not on PS5.
Season 4 launched this morning, and buried within the patch notes is word Warzone now has 120hz support for PS5.
In November, Modern Warfare developer Infinity Ward added 120fps support to Warzone on Xbox Series X. Activision declined to comment when contacted by Eurogamer at the time, leaving us to assume the reason for this difference had to do with the way Sony handles backwards compatibility.
