You can disable it by turning off the HUD if you wish, Edit the UserInput.ini in: Documents\WB Games\Batman Arkham City\BmGame\Config and add this line to the bindings. .Bindings=(Name="H",Command="ToggleHUD", Control=False, Shift=False, Alt=False) Or any other key which is not in use.
Maybe theres a way to take what RecluSe has here, but instead of turning it off, can it be repositioned. The hud i mean, like a x,y,z sorta thing.
