Disable Mouse Acceleration
Simple .ini file to disable mouse acceleration in Starfield.
Disable mouse acceleration (speed ramping up when moving the mouse) when looking around, making it linear as it should be.
To install the mod, simply download the .ini file and place it in:
C:\Users\[Your-User]\Documents\My Games\Starfield
The file contains the following, which can be tweaked to your desires:
[Controls]
fMouseHeadingXScale=.03738
fMouseHeadingYScale=X
bMouseAcceleration=0
For example if using a super-wide resolution such as 3440×1440 the following settings might suit you better:
[Controls]
fMouseHeadingXScale=.03738
fMouseHeadingYScale=.05016
bMouseAcceleration=0
If you’re experiencing for example that looking up and down feels a bit fast/slow, play with the Y-scale, looking left and right; the X-scale e.g.:
[Controls]
fMouseHeadingXScale=.03738
fMouseHeadingYScale=.06645
bMouseAcceleration=0
My preferred settings (16:9 screen):
[Controls]
fMouseHeadingXScale=.02250
fMouseHeadingYScale=X
bMouseAcceleration=0
