#1 Fallout 4 Crash Fix on Startup
There are a few things you can try to fix the notorious startup crash. First things first, you should make sure that your GPU drivers are up to date (both Nvidia and AMD).

If that doesn’t work, and you are using a VPN, try disabling as there have been some reports that VPNs are causing Fallout 4 to crash.

You can also try running the game in borderless window as it can also solve your problem. Some users have also reported that rolling back their driver version from beta to full has fixed the issue for them.

#2 Fallout 4 Crashes During Loading Screen
You should try the fixes mention in #1. Also, if you are running any third party applications in the background like Afterburner or any digital recording tool.

#3 Fallout 4 Potential Fix for AMD Crashes
Some users have reported that AMD crash can be avoided by rolling back the beta driver version to a full version. So if you are facing a crash too and nothing else has worked, I think it’s worth of a shot.

#4 Fallout 4 Performance Boost for Nvidia Users
Nvidia Streamer service can be a culprit. So if your PC is good enough and you are experiencing poor performance, try disabling Geforce experience to boost the performance. Needless to say that you should also have latest drivers for better experience.

#5 Fallout 4 – How to Fix Mouse Acceleration Issue
You will be able to locate Fallout4Prefs.ini file in your documents for Fallout 4. This is the config file you can use to tweak stuff.

Open it and find the command that says: iPresentInterval. Set it to 0 and also find the command that says: bForceIgnoreSmoothness. Setting it’s value to one should disable acceleration.

#6 Fallout 4 – How to Remove FPS Cap
If you are getting locked 30 FPS with V-sync enabled, try running the game in borderless window. Also, setting iPresentInterval command to 1 can even get you past 60 FPS.

#7 Fallout 4 Disk Write Error
Make sure that you have sufficient hard disk space free and that you are not using FAT file system somehow on your storage device.

#11 Fallout 4 – Very Long Loading Times
For now, it is known that the game is facing long loading times on all the platforms. PC users however, can get the reduced loading times if they are using an SSD. The game takes 6-8 seconds to load while and HDD can take upto 40 seconds.

Bethesda Might fix it in future but for now, an SSD is the only solution right now.

#12 Fallout 4 – Game Crashes Every 15-20 Minutes
If none of the above mentioned fixes have worked for you, try the fix mentioned in #10. Just make sure that you have updated drivers and you aren’t running any third party applications in the background.

#13 Fallout 4 – No Sound In-game or Menu .dll Errors
Try running the directx setup in _CommonRedist DirectX Jun2010 folder should resolve the issue for you. These setups will also remove any other .dll related errors you are facing.

#14 Fallout 4 Settings Not Being Saved
You need to make sure that your Fallout4Prefs.ini is not set in Read-Only mode as it will prevent the program to write any changes you make in the file.

If nothing else works, delete the file and restart the game. This time a new file will be created and things should get back to normal.
