Fixing Low FPS Issues In Fallout 76 On PC: A Comprehensive Guide

When you first load Fallout 76 on PC, you might be surprised to see a significant drop in frames per second (FPS) compared to other games. Many players report experiencing FPS rates between 30 and 50, along with frustrating stuttering as they navigate through Vault 76, even after adjusting the graphics settings to the lowest possible levels. Fortunately, there is a simple and effective solution to tackle this low FPS problem, which can be implemented outside of the game itself.

This issue has been a persistent challenge for PC players since the game's launch. Through community research, players found that the root cause is linked to Vsync settings. Interestingly, there is no option within the game to disable Vsync, which is enabled by default on all PCs. Consequently, if players do not modify the game files, they will be stuck with Vsync enabled, effectively capping their FPS and leading to an unsatisfactory gaming experience.

To resolve this FPS issue, follow the steps outlined below to uncap your FPS and disable Vsync in Fallout 76. By making these adjustments, you can enhance your gameplay significantly and enjoy a smoother experience as you explore the vast world of Fallout 76.

Steps to Fix Low FPS on PC in Fallout 76

To address the low FPS problems in Fallout 76, follow these steps carefully:

• Exit Fallout 76 and navigate to the following file directory: C:\Users\YOURUSERNAME\Documents\My Games\Fallout 76.
• Locate the Fallout76Prefs.ini file within this directory.
• Open the file and press Ctrl+F to search for the word “Interval.”
• You will find a line that reads: iPresentInterval=1.
• Change this setting to: iPresentInterval=0 to disable Vsync.
• After making this change, click on “File,” then “Save As” to save your changes, and exit the directory.
• Restart Fallout 76, and you should notice a significant improvement in your FPS.

If you followed all the steps correctly, your FPS should now be higher, and you may also notice a reduction in stuttering during gameplay. However, it’s still advisable to keep your graphics settings relatively low, as increasing them to maximum levels may not yield a substantial improvement in visual quality.

As a final tip, consider capping your FPS to 90 using your GPU software, such as the Nvidia Control Panel. An uncapped FPS can lead to various issues with the game engine, including getting stuck in indoor areas or even experiencing game crashes. By setting your FPS limit to 90, you can avoid these problems and enjoy a smoother gaming experience.

Fallout 76 is currently available on PC, Xbox, and PlayStation.

By following these steps, you can overcome the frustrating low FPS issue and immerse yourself in the post-apocalyptic world of Fallout 76 with a significantly improved gaming experience!
