Low specifications of the Computer: This is the most common reason why users experience lagging in Fallout 4.

Changing the priority level in the task manager works here.

Low Task Manager Priority: If the Fallout process isn’t of priority in the task manager, the computer will not treat it like a real-time game and will hesitate in giving it huge resources.If they themselves are not updated properly or are having issues in operation, you will not get the desired output. Outdated Graphics Drivers: Graphics drivers are the main components which communicate between the game and the hardware.Setting the GPU to maximum performance works here. Conflicting GPU Settings: We also came across several instances where the GPU was bottlenecking the game itself because of its power-saving and other settings.Here, lowering the settings or enabling the Windowed mode helps.

High in-game settings: There are also situations where the in-game settings are set very high and there aren’t enough resources to cater to the requirements.

Here, we can try diagnosing and closing all third-party applications running in the background.

Third-party applications: If there are other applications running in the background which are consuming your resources, Fallout will not get its required computational power and hence, cause lagging in the game.

FPS Limit: There is by default, an FPS limit in Fallout which automatically reduces the maximum number of frames per second which you can achieve in your computer.
