Why is Call of Duty 439GB on game pass? Xbox series x

Like I said. There were no separate elements to install. All 439GB allocated to base game.

found fix:

Decided to start installing game. When I did so, all different elements began to download separately(bo6 multiplayer, campaign, warzone, etc.) so I stopped the download, looked again and all elements were broken up. Must be a visual bug in gamepass and Xbox store

You need to choose the elements you want to install

He might be the only person reporting this here, but he's so far from alone. I play backwards compatible Call of Duty games with dozens of people, and they all notice and agree that there is significant input lag when playing any of these games.

I can confirm that the issue is present on Call of Duty 4, Call of Duty World at War, Call of Duty Modern Warfare 2, Call of Duty Black Ops, Call of Duty Modern Warfare 3, and Call of Duty Black Ops 2. I can confirm that this issue is present on Xbox One and Xbox Series S. These people collectively can confirm the issue is present across Xbox One, Xbox One S, Xbox Series S, and Xbox Series X. Several of them have purchased an Xbox 360 instead to avoid it.

I hope this issue can be passed along and resolved at some point. I can deal with it, but I certainly notice it and find it rather annoying.

From what I can tell, to access the Series X version of the game, you need the Cross-Gen bundle...once you buy that, you should then be able to download and install the Series X version. Without the cross-gen bundle it will, presumably, just install the XB1 version

From the Store page:

"For digital owners of the Call of Duty®: Black Ops Cold War Standard Edition, this upgrade will unlock the Call of Duty®: Black Ops Cold War Cross-Gen Bundle, giving access to the Xbox Series X|S version of the game. After upgrade purchase, search in the Xbox store for the Call of Duty®: Black Ops Cold War - Cross-Gen Bundle to install the Xbox Series X|S version of the game."
