I am looking for what user.ini. or ut.ini. lines are critical for steadying a jumpy or jerky mouse cursor while attempting to aim or even when shooting. Merely changing the mouse sensitivity settings in-game or in the ini. files seems insufficient since while the mouse moves slower (which makes snap turning and firing harder) it really still seems to leave the cursor still a bit unstable. Part of the problem occurs because of pinky dragging when the mouse is being moved on the mouse pad or when a firing button is pushed. Still I have spectated many games watching players with good aim jump around with a cursor that moves quite smoothly over the screen. The smoothing settings then??? In-game changes are insufficient for me so what can I try in the ini. files to smooth and/or steady the mouse cursor even further? If it helps to know I have a Logitech MX518 gaming mouse.
