Call of Duty: Warzone runs at 120fps on Xbox Series X, but why not on PS5?

Activision has added 120fps support to Call of Duty: Warzone on Xbox Series X, but not on the PlayStation 5.

Warzone gets 120fps on Xbox Series X

The support, which was not mentioned in Modern Warfare's latest patch notes published this week, was spotted by players when they tested the battle royale on Microsoft's new console.

Here's an Xbox Series X screenshot:

It seems strange that a game which has crossplay enabled by default across all platforms would run at different frame rates on Xbox Series X and PS5.

Why does Warzone not run at 120fps on PS5?

Warzone, which comes up as a PlayStation 4 app when it's downloaded on PS5, does not boot in 120Hz, and there are no in-game menu functions to enable it.

If 120fps support is in the game, it's currently inaccessible.

Given Warzone is running on PS5 via PS4 backwards compatibility, maybe it would require a full port to PS5 in order to enable 120fps on Sony's console.
