It does almost nothing.
Treyarch have gone and released a new update for Call of Duty: Black Ops 3, Activision support announced on Twitter today. It’s not a big update at all, and doesn’t even seem to do much – Activision themselves only confirmed that it changes the Game Settings menu a bit – so don’t expect there to be any big, game changing improvements. Honestly, I don’t even know why they bothered to talk about this outside of the patch notes that must surely accompany the update’s installation on consoles and PC.
“Game Settings have changed. We released a small update this morning for PS4/Xbox1/PC and continue to develop & test additional updates,” they said.
The good news is, they also confirmed that they are working on new game updates, which means more major issues – and Black Ops 3 does not necessarily have a whole lot of them to begin with – will thankfully be addressed soon as well.
