I have done every little thing that has been recommended by various people online and I still have mouse acceleration every time I right click and aim with a weapon.īut, if I right click to aim at an enemy when using biotic powers then come out of that little pause screen, it doesn't affect my sensitivity. I turned the mouse sensitivity down on my mouse, disabled the mouse programme, and in the ini file I disabled mouse smoothing, vsync, mouse dampening, lowered base sensitivity to really low etc. I started playing Mass Effect 2 recently and noticed any time I right-clicked and zoomed in with a weapon, afterwards my mouse would suddenly have a ridiculously high sensitivity.
