PlayStation 5 users have been playing the PlayStation 4 version of Call of Duty: Black Ops Cold War by accident!
Why PS5 users are playing the PS4 version by accident
If you buy the Cross-Gen bundle or the Ultimate Edition of Treyarch's first-person shooter, you receive the PS4 version and the PS5 version.
After you buy the game from the PlayStation Store, you're able to pick and choose which parts of Black Ops Cold War to download.
If you hit download all, which most players are doing so in order to access all the modes available - you download the PS5 and the PS4 version of the game.
And after that's done, it appears the PS5 may default to the PS4 version when you hit the play button.
How to make sure you're playing the PS5 version of Black Ops Cold War
In order to play the PS5 version, you need to hit the three dots icon next to the play button, and change your selection to the PS5 version.
This briefly refreshes the user interface, and from there hitting play will boot the PS5 version.
If you're playing the PS4 version, you're missing out on all the benefits that the PS5 version holds, including faster loading times and DualSense tech support.
COD: Black Ops Cold War PS5 download bug
There are some reports that this situation is throwing up an additional problem for PS5 users.
Whilst you're able to delete the PS4 version from your PS5 if you don't want to play that version, it seems there is a download queue bug preventing people from downloading the PS5 version if they only have the PS4 version installed on their PS5.
Reports indicate a factory reset will fix this bug for most players.
