Fallout 4 – Increase FOV, Disable Mouse Acceleration & Improve Mouse Aiming

Fallout 4 is now available and apart from that really awful game engine speed issue, the game appears to be suffering from mouse acceleration side effects. And while there is no in-game option to completely disable it – or change its default FOV – PC gamers can use the following tweaks in order to improve their PC gaming experience.

Fallout 4’s FOV is locked at FOV 70/80, however you can adjust/tweak it following this guide.

“Open both Fallout4.ini and Fallout4Prefs.ini
In the [Display] section of both files, add the following lines:
fDefaultWorldFOV=90
fDefault1stPersonFOV=90
90 is the default FOV of most FPS games, but you can change that to whatever makes you happy”

Regarding mouse acceleration, PC gamers can disable it via this way.

“Open both Fallout4.ini and Fallout4Prefs.ini
In the [Controls] section of both files, add this line:
bMouseAcceleration=0”

In order to improve mouse aiming, however, PC gamers will need to also use the following tweak as the default vertical sensitivity is half as much as the horizontal.

“Open Fallout4.ini
In the [Controls] section, find fMouseHeadingXScale
On the next line, make fMouseHeadingYScale 2x the amount of fMouseHeadingXScale”

Our PC Performance Analysis for Fallout 4 will hopefully go live later this week, so stay tuned for more.
