Installation:

1. Extract this .txt file into your Starfield game directory (Example: "D:\Games\STEAM\SteamLibrary\steamapps\common\Starfield")

2. Go to your StarfieldCustom.ini in "C:\Users\Username\Documents\My Games\Starfield" (if you don't have one then create one) and add:

"sStarting Console Command = bat FlightCamera" (no quotes or spaces except between bat and FlightCamera, java doesn't let us paste these lines) under the [General] section, if there is no [General] section add it so it looks like this

 [General]
sStarting Console Command = bat FlightCamera

OR

";bat FlightCamera" to the end of your pre-existing line under [General]

3. Make sure your StarfieldCustom.ini contains this as well:

[Archive]
bInvalidateOlderFiles=1
sResourceDataDirsFinal=

Step 4 is now included in the .txt file.

4. For the vanity camera distance (idle camera), SetGS doesn't seem to work so put this line into your StarfieldCustom.ini as well:

[Camera]
fDefaultShipAutoVanityZoomScale=4.5000

OR use this command via the console

setini "fDefaultShipAutoVanityZoomScale:Camera" 1.500//change this default value to the level of zoom you prefer

I adjusted the Y axis of the camera to keep larger ships on screen while turning with the new camera speed adjustments for acceleration, if the camera is too far from the ship for your liking you can decrease this value in the .txt file:

SetGS "fFlightCameraOffsetBaseY:FlightCamera" -75.000
//default=-5.780

These are all of the settings within the .txt file for reference if you'd like to make further adjustments before dropping it in your Starfield game folder:

SetGS "fFlightCameraFOV:FlightCamera" 90.000-FoV, self explanatory
//default=90

SetGS "fFlightCameraOffsetBaseY:FlightCamera" -75.000-How far the camera will be from your ship
//default=-5.780

SetGS "fFlightCameraOffsetBaseZ:FlightCamera" 9.110   -How far down the screen your ship will appear
//default=5.110

SetGS "fFlightCameraSpeedOffsetMinX:FlightCamera" -1.500 -Additional leeway for -x axis camera movement based on speed (pushes camera left)
//default=-8.000

SetGS "fFlightCameraSpeedOffsetMinY:FlightCamera" -35.000       -Additional leeway for -y axis camera movement based on speed (brings camera closer)
//default=-16.000

SetGS "fFlightCameraSpeedOffsetMinZ:FlightCamera" -1.500 -Additional leeway for -z axis camera movement based on speed (pushes camera down)
//default=-8.000

SetGS "fFlightCameraSpeedOffsetMaxX:FlightCamera" 1.500 -Additional leeway for +x axis camera movement based on speed (pushes camera right)
//default=8.000

SetGS "fFlightCameraSpeedOffsetMaxY:FlightCamera" 0.000 -Additional leeway for +y axis camera movement based on speed (pushes camera away)
//default=2.000

SetGS "fFlightCameraSpeedOffsetMaxZ:FlightCamera" 1.500 -Additional leeway for +z axis camera movement based on speed (pushes camera up)
//default=2.000

SetGS "fFlightCameraOffsetMaxLandedDistance:FlightCamera" 200.000-Distance camera will be when ship has landed
//default=38.000 (doesn't seem to make much difference higher than 70ish)

SetGS "fFlightCameraOffsetMaxLandingHeightOffset:FlightCamera" 200.000-I honestly don't even notice much difference with this one one
//default=38.000 (doesn't seem to make much difference higher than 70ish)

setini "fDefaultShipAutoVanityZoomScale:Camera" 4.500
//default=1.500
