PC players have been dealing with this specific issue in Fallout 76 since the game's initial release. After some investigation by the community, the cause was discovered to be probably the V-sync only. For some reason, there's no option to disable Vsync within the game's graphics settings, and it's enabled by default on all PCs. This means without going into the game files, you’ll be forced to have Vsync enabled, which essentially caps your FPS.

To fix your low FPS problem, follow the steps below to uncap your FPS and disable Vsync in Fallout 76:

1. Exit Fallout 76 and go to the following file directory: C:\Users\YOURUSERNAME\Documents\My Games\Fallout 76

2. Find the Fallout76Prefs.ini file in the directory

3. Open it and use Ctrl+F to search for the word “Interval”

4. You should find a setting that reads: “iPresentInterval=1”

5. You need to change that setting to read: “iPresentInterval=0”

6. This disables Vsync in Fallout 76. When you’re done, go to the top left of the screen, click “File,” then “Save As,” and exit the directory.

7. Open Fallout 76 back up, and your FPS should be much higher

If done correctly, you should no longer experience lower FPS. However, I still recommend keeping your graphics settings relatively low in Fallout 76, as increasing them won't significantly improve the game's visuals.

As a final note, I also suggest capping your FPS to 90 using your GPU software (Nvidia Control Panel) as long as you have NVIDIA Graphics Card. A fully uncapped FPS causes issues with the game engine and can lead to you being stuck in indoor buildings without even doing anything. I had my FPS uncapped and couldn’t move as soon as I entered a building, even after pressing WASD and space bar. Leaving your FPS uncapped can also lead to game crashes and other problems, but if you set it to 90, you won’t have any unexplained issues.

If you have Nvidia Graphics Card, then you can cap your FPS very easily by using NVIDIA Control Panel.


You will see 2 tabs there:
"Global settings" and "Program settings".
Click on "Program settings", then check if the Fallout 76 appears in the default list.
If it doesn't - un-check "show only programs found on this computer".











And You're ready to play again in a good Framerate.
Thank you for using my guide. Safe travels.


Ohh, and don't forget to drop your PC Spec down there in the comments with which you suffered in a low framerate! :3
