Fallout 4 is out now of PC, PlayStation 4 and Xbox One. Many PC gamers wants to know how to unlock FPS, change FOV, Skip the intro video, activate 21:9 support, remove mouse acceleration and many other things. This Ultimate Fallout 4 PC Error guide provides details on how to do all these things.
1: Unlock Frame Rate
Many PC gamers have discovered that Fallout 4 is locked at 30FPS for them. This is bizzare because for others it appears that Fallout 4 runs at locked 60FPS. To unlock Fallout 4 frame-rate or this 30FPS cap issue follow the steps provided below.
To unlock frame rate open Fallout4Pref.ini (simply search windows for it, but it is in your documents). Note making a backup isn’t neccessary as if you simply delete Fallout4Pref.ini the game will auto generate new one next time it is opened.
Search for the line iPresentInterval=1, and change it to iPresentInterval=0
Next to use vsync got to the nvidia control panel or amd equivelant and apply vysnc here to avoid nasty screen tearing, as the above completely removes any frame rate cap.
Another possibly solution that may work for you is to play in a bordeless window mode.
2: Remove Mouse Acceleration
Mouse acceleration appears to be on by default in Fallout 4. To remove it, Open Fallout4.ini (just do a search for it, or find it in your documents folder). Scroll down to [Controls], and under this add the below line:
Note: This will not remove it from menus or similar, but it removes it from ‘within’ the game.
3: Skip Intro Video When Loading Game
To skip the intro every time you laod up Fallout 4 go to a place where you have steam installed, go to steamapps, then common, then Fallout 4, then Data, then Video and delete the below file:
NOTE: I would recommend making a backup of this elsewhere as whilst you can simply verify the integrity of your game files it is simply simpler to backup this file
4: How To Change Fallout 4’s FOV:
Changing FOV in Fallout requires a bit more of a work. Firstly go to your Fallout4.ini and under [Display] put the below:
Here this XX means your desired FOV. I feel 90 is what will probably be best for most.
Next go to the Fallout4Prefs.ini and do the same as above, under [Display] put:
Again, here this XX means your desired FOV. I feel 90 is what will probably be best for most.
Next go to where you installed steam, open steamapps, then open common, then Fallout4, then Fallout4 again (a folder called Fallout 4 is in another folder called Fallout4. Next open the Fallout4Prefs.ini here and once again under [Display] add the below:
Again, here this XX means your desired FOV. I feel 90 is what will probably be best for most. That’s it, your Fallout 4 FOV should now be changed.
5: How To Add 21:9 (Ultrawide) Support:
To run Fallout 4 at 21:9 without issue simply open Fallout4Prefs.ini in your documents (or just search for it), and change the following lines to how they are below:
Here XXXX is whatever your horizontal resolution is aand YYYY is whatever your vertical resolution is. Next do the same for the second Fallout4Prefs.ini located in wherever you insalled steam, then open steamapps, then common, then Fallout 4, then Fallout 4 again.
