The keys are setup correctly in AH3 for Short, Ground, Medium and Full Vis ranges. When you press a key to change a range, the new vis range is shown as with the old AH2, but following that is the text "not implemented." Unsure what that means, but I do know that none of the vis range keys has any effect on the view. I'm stuck on some view and with the different graphics can't even tell what view that is. Some players claim there are no more alternate vis views, but if that is the case why are the menu options for different views still available. Even more confusing is that some players say their views change as always.
