Hello,
My problem is the same as yours Ferryman, and actually Warzone function when the registry key value is “true” “HKEY_CURRENT_USER \ SOFTWARE \ Blizzard Entertainment \ Battle.net \ Launch Options \ ODIN LAUNCH_64BIT”.
And when the game is restarted this value changes and by default remains on “false”.
In addition there is strange behavior when browsing in the game all the graphics settings change (low resolution) when I return to the choice of games menu (warzone, mw or CW).
I hope that a correction update will be made as soon as possible.
