According to this article, Fallout 76 Beta's physics are tied to its framerate. Fans of Fallout 4 know that this is nothing new but it seems the issue is still present in the latest version of the game.
By default, the Fallout 76 beta‘s framerate is locked down, and there’s no way in the settings to change that. But on the PC version, users have found that by simply changing a few lines in the game’s .ini file—just like you can in Bethesda’s other games like Skyrim—you can speed up the framerate, and at the same time speed up the rest of the physics in the game up as well.
