Fallout 4 for PC can be buggy sometimes. Find out how to fix common errors with our guide! Compiling a list of all the weird things that impede progress, we'll show you how to make the game play as it was meant to be played.

Fallout 4 Errors and Fixes

Game failed to launch:

  1. Verify the game cache files and restore the missing files.
  2. If you are using a 32 Bit you can not play. 32 bit operating system is not supported as it requires at least 8 Gigs of RAM.

Game gets stuck on loading screen:

This happens because of missing / corrupt files. Often it’s because of your Anti-virus program so disable it. Also verify the integrity of game cache files in Steam. Restore the missing files and install the game.

Mouse acceleration issue:

It is not an unknown problem and lots of players have it these days not just in Fallout 4. Easy fix is:

  1.  Go to: C:\Users\username\Documents\My Games\Fallout4\
  2.  Open Fallout4config and change iPresentInterval=1 to iPresentInterval=0 and do the same with Fallout4prefs (here also change bForceIgnoreSmoothness=0 change that tobForceIgnoreSmoothness=1)

Game crashes to desktop on startup or you get some random crashes:

It’s not possible to say exactly what is wrong but the most common issues are:

  • Crashing on startup
  • Crashing during the game.
  • Crashes after few minutes of gameplay
  • Crash after changing the settings.
  • BSOD

    I’d highly recommend to not have users download and run a program that claims to “fix” DLL errors, as the errors vary. It’s widely advised against, and what may work well for one is not always going to work well for another. I don’t know how many times I’ve known people to download tools like that and it give them “errors” and download “fixes” that only made things worse. If anything, users should open command prompt (as administrator) and type in “sfc /scannow” — without quotations. Running that command will scan their protected system files and replace corrupted files with a cached copy that is located in a compressed folder on their PC. If they run that command and all comes back good, as in it shows no errors, but you still get errors with Fallout 4, then you need to check the Event Viewer (on Windows 10, just type in the search bar “event viewer” and it will pop up) to see what specifically is causing the problem when the game crashes. A lot of the time it is the program/software/game itself and not so much the system … especially if everything else is running well. Sometimes reinstalling the DX files and Visual C++ (located in the _CommonRedist folder of the Fallout 4 directory) can help depending on the issue, as well. Verifying the game’s integrity, reinstalling the game completely. keeping all drivers up to date (mobo, gpu, windows, etc )…. anything but using a third-party tool for DLL problems.

    I read somewhere that suggests downgrading nvidia driver back to 355.60. That actually works for me. So far I’m not having the bsod every 10 minutes anymore.
