Oh... man. You are going to have your mind blown. We've been working on this for a while.
AutoHotKey is an scripting application that lets you do all kinds of keyboard and mouse automation for windows. WeltallZero and I have been using it to (along with a few other tricks) simulate the right mouse button constantly being held down, and only released during certain conditions.
The effect of this is you get true third-person shooter control (the right stick always moves the camera by default). It feels
unbelievably good.
We're actually going to be releasing an updated, ultimate, final (?) verison of our script and profiles for Xpadder (everything you need will be in one package) today.
