Hi there! This guide will show you, how you can remove the framecap in Fallout 76.

1. Go to the following path: C:\Users\*Your Username*\Documents\My Games\Fallout 76

2. Open "Fallout76Prefs.ini" with your preferred text-editor,

3. and search for "iPresentInterval=1"

4. Set the variable to "0" so it looks like the following: "iPresentInterval=0"

5. Save.

And that's it! Your performance should be a lot better now. Especially indoors.
If you have any questions, feel free to ask me in the comments, or add me. :)

If your water texture seems to be black after editing the file, do the following:

1. Open "Fallout76Prefs.ini" with your preferred text-editor again,

2. and search for "bScreenSpaceReflections=0"

3. Set the variable to "1" so it looks like the following: "bScreenSpaceReflections=1"

4. Save.

And that's it! :)

If it still remains black, please add me for further troubleshooting!! :)

If you encounter any other problems after applying this fix, please try limiting your FPS to a max 144FPS in your GPUs driver or MSI Afterburner (or Program of choice) :)
