Is there a way to disable the mouse acceleration? There seems to be some kind of delay when turning Aquila.

I think its intentional. To make it feel more like your in a really heavy giant robot.

But I don't think it had this "acceleration" in the console version. That's why I wonder if there is a way to turn it off.

It wouldn't be as noticeable with a gamepad as with a mouse. Analog sticks are less starty and stoppy. I could pull out my xbox, and check to be sure, but im terminally lazy. I don't think it matters anyway. I looked, but I have yet to find any way to disable it in the PC version.
