Tried to play ARMA 3 Old Man again today and the camera spins around crazy fast looking at the ground as soon as I touch the mouse or if I invert it, the same but looking at the sky.
The mouse works fine in the menus.
I somehow got in a vehicle the steering is full to the right and fights to stay there if I try to use the keyboard.
I deleted all my saves and started a new game to see if that would reset it, no joy.
I bought the Cold War expansion just now to see if maybe that would sort it, a different driver or something, no joy.
I'm guessing as it's been updated thats the issue, can I go back to a patch version that works?
