The faster your frame rate, the faster you move. What's nice, anything in a single-player game that Bethesda is used to making, but not fine for a multiplayer-only release like Fallout 76 where to change the player's framerate is as simple as entering a few lines of code.
By default, Fallout 76 beta's frame is locked down and there is no way in the settings to change it. But on the PC version, users found that by changing a few lines in the game's .ini file, just like you can in Bethesda's other game like Skyrim -y can increase the speed of the frame rate and at the same time increases the speed of the rest of the physics of the game as well.
In singleplayer games, this is just a way to pass the time or make news, but in a multiplayer experience it is to have different players moving at different speeds, an absolute disaster.
Bethesda is aware of the problem, but told Polygon "a repair will not be out until the game is launched."
Good luck to PC players.
] Between this and self-extinction, it's no wonder Bethesda warned us: "We all open up to all the new spectacular issues none of us have met" when this beta started.
