Be _sure_ to crank the mouse speed down, or the nubs will be useless for sure.
For me ..
With mouse speed down, right nub can work for mouse-look okay (ie: to look around.)
Left nub gets 'stuck' a lot; if I press forward, the guy will be stuck going forward forever until I manage to cancel it with another forward, or perhaps dpad.. I forget.
I use dpad for move, and right-nub for look, and triggers for fire and weapon rotate.
I don't touch the left nub, for lava poors from the sun when you do that
(Sorry pickle, I never thought to look into the code)
