Before the patch the gunner view and aim were fixed with the movement of tank or the view circle did not appear before. Now the view and aim are no longer fixed with the movement of the tank or now a view circle appears, therefore when the tank moves the view can go black or you can no longer see outside of the tank. The previous method was much better (no view circle).
Also, the gunner view in the Sherman tank is much closer than before. It would be nice if the gunner view could be adjusted, i.e. travel mode, close range, long range.
