It is briefly, it's shader data apparently, but it looks like it's an endemic problem on how they have to patch the whole game (meaning, a lot of assets) to change one thing on only one of the modes.
The video suggests its Shader data for the map, since it has to keep everything, including the insides of buildings which are still very detailed.
I discovered today as well lol it was founded on December 2017: https://www.infinityward.com/news/archives/announcing-infinity-ward-poland
Changes/upgrades etc done to the base game translate to BR mode and vice-versa. If they can compress the various parts to make them work more efficiently, then that would reduce for both, Who knows how they plan to do it.
If what IW said last week is true, they're going to allow per-mode installs, so you can uninstall the campaign, or the MP or Warzone separately.
The game still needs those shader data even when playing normal multiplayer. The maps in multiplayer/coop don't exist in vacuum separately on their own, they are essentially chunks of the large map that exist in warzone. So any changes made to that part of the map in warzone translates to multiplayer/coop and vice versa.
Sorry, I was wrong, they said it for PC which doesn't have a package manager.
The map existed in the game since the game released way before warzone launched...that's where spec ops missions take place.
Must help a lot with performance, especially on console. It's a really good looking game. I can imagine Valve took similar approaches with Half-Life: Alyx which is crazy performative for VR.
Strange, because Warzone randomly stutters for me on PS4 Pro. The campaign was totally fine, but Warzone is a mess.
It might have to do with your anti-aliasing setting. If you aren't using the temporal anti-aliasing the game looks very shimmery.
See the issue is that I already am running with the Filmic SMAA x2 option
