Fix Mouse Acceleration and FOV in Fallout 4 on PC

Hello, fellow gamers! If you were like me and couldn’t wait to play Fallout 4 on PC, you were probably also like me and very disappointed to find out that Bethesda didn’t take the time to set reasonable defaults for mouse acceleration and include a Field of View (FOV) slider?

C’mon Bethesda, you’ve been making games for a long time; you should know better.

Luckily for you wanderer, there are some very easy fixes for these oversights. All you need to know is how to edit .ini files (don’t worry, they’re basically text files you can edit in Notepad) in this location:

C:\Users\$USERNAME$\Documents\My Games\Fallout4\.

Disabling Mouse Acceleration

  1. Open Fallout4.ini and Fallout4Prefs.ini
  2. Under the [Controls] heading in each file add this new line:
  3. bMouseAcceleration=0

Enjoy your unhindered aiming!

Setting a Higher Field of View (FOV)

The default FOV for Fallout 4 is 70. Say what? It blows my mind that first-person games are being released in 2015 with FOVs below 90. Ever heard of motion sickness induced nausea, game developers?

  1. Open Fallout4.ini and Fallout4Prefs.ini
  2. Under the [Display] heading in each file add these two lines:
  3. fDefaultWorldFOV=100
  4. fDefault1stPersonFOV=100

Keep in mind 100 is just my preferred FOV, you can set the number to whatever you’d like.

Hopefully, your Fallout 4 experience will be a little better with these fixes. Now go have fun, and remember: Quicksave early, Quicksave often.
