This method will not disable achievements.
Locate this directory C:\Users{YOUR NAME}\Documents\My Games\Starfield
In the same folder as StarfieldPrefs.ini you need to create a new file named StarfieldCustom.ini. Make sure the file extention name is correctly set as a ".ini" file.
If your file is automatically created as a text file you need to find the view tab on the top of your file explorer. Click this tab and make sure File name extension is checked here. Now you can remove .txt from your file name.
FOV
in the new file StarfieldCustom.ini put these lines, You can change the number to whatever fov you wish:
[Camera]
fFPWorldFOV=100
fTPWorldFOV=100
Pilot FOV (optional)
[FlightCamera]
fFlightCameraFOV=100
Mouse acceleration
To remove mouse acceleration enter these lines into StarfieldCustom.ini
[Controls]
bMouseAcceleration=0
fIronSightsPitchSpeedRatio=1
fPitchSpeedRatio=1
Sync horizontal and vertical sensitivity (optional)
If you already added [Controls] to your file, then skip the "[Controls]" line and add the rest of the values under your existing [Controls] section.
[Controls]
fMouseHeadingXScale=0.021
fMouseHeadingYScale=0.03733
You can calculate the fMouseHeadingYScale if your monitor's aspect ratio is not included in the examples using this formula:
fMouseHeadingXScale x (Aspect Ratio)
e.g.
0.021 x (16/9) = 0.03733
fMouseHeadingYScale for Common Aspect Ratios/Resolutions
16:9
0.03733 for 1920x1080, 2560x1440, 3840x2160 etc.
16:10
0.0336 for 1920x1200 etc.
