Activision and Raven are deploying Call of Duty Warzone Season 4 Update 1.38, which adds 120Hz support on PlayStation 5.

Support for this refresh rate has already been available on Xbox Series X since late last year, but 6 months later, PS5 players can now also play the game at the high refresh rate on supported displays. In addition to adding to support for 120Hz, the Season 4 update for Warzone also packs new weapons, new multiplayer maps, new Points of Interest in Verdansk, new quests, and numerous improvements.
