Is there a way to enable non-linear mouse acceleration in Deus Ex: Human Revolution?
I'm asking about a non-linear translation of physical mouse movement speed to angular speed of the in-game view. This type of translation feels very natural to me, as it's implemented in many desktop operating systems and in most FPS games I've played.
I don't know if acceleration is the right term for this, but I remember Windows' mouse control panel calling it that way in some older versions of Windows. In Window 7 it's called enhance pointer precision and is enabled by default. It's called pointer ballistics by Microsoft and is described in this article.
I can't find any option controlling this in the game's menu or it's setup utility (launched from Steam by choosing Setup Deus Ex: Human Revolution after double clicking the game in the game library). Without this option, I find aiming very hard because if I configure the mouse sensitivity to get acceptable aiming precision, making a 180-degree-turn is impossible without either moving my wrist or lifting the mouse and moving it in the reverse direction.
