The studio noted that a huge number of people are playing on the previous generation consoles.
Treyarch, in a conversation with journalists, warned that Call of Duty: Black Ops 7 will look very bad on PlayStation 4 and Xbox One consoles.
We still believe that we can create a game by fully realizing the intended gameplay. Obviously, the visual experience will be far from desirable.
At the same time, Miller noted that the game was initially developed for PlayStation 5, Xbox Series X|S, and PC, and only then did the studio work on optimization for older platforms. The developers did not compromise or sacrifice for the sake of PS4 and Xbox One. If something didn't work on the previous generation consoles, it was simply turned off.
We never think about the old generation when developing new features. We knew we wanted to add Theater Mode, but it is not supported on older consoles. This is not a reason to abandon the feature — we simply disabled it for the previous generation.
