If you’re experiencing lagging issues and slow performance on an ultra-modern PC running Fallout 4 then follow this tutorial to Fix Fallout 4 FPS Drop. Fallout 4 is as much about gathering resources in the same way as fighting off enemies and completing quests. From the worn-out Raider’s clothes to an old manager’s office in a store, things are all over the place. 

For those who are new to the series, Fallout 4 is the best way to begin as every other. It gets the player with a character who is out prior to the start of war it does a good job of establishing an environment, and provides an unambiguous start in the story’s direction. But, before looking for a the solution, it is important to know the reason behind this. What kind of lag does it ?

What is causing the lagging In Fallout 4.

After receiving numerous user feedback in addition to our personal investigation We discovered that the slowdown of Fallout 4 was caused by various reasons. The reasons are as follows:

NOTE: Not all the causes could be relevant to your particular situation. If you are unable to find one that don’t correspond to your particular situation Don’t fret; simply go on to the solution and we’ll have the game going quickly.

  • FPS Limit There exists, by default an FPS limit set in Fallout that automatically decreases the maximum amount of frames per second you can get on your personal computer. Modifying the settings will work in this scenario.
  • Third-party apps:If there are other programs that are running in the background and consume the resources of your computer, Fallout won’t be able to access the required computing power, and, as a result, will experience lag within the game. We can attempt to identify and close any third-party application that are running behind.
  • High settings in game:There are also situations when the game’s settings are very high, and there aren’t enough resources available to meet the demands. This is where lowering the settings or activating the Windowed mode will help.
  • Conflicting GPU settings: We also came across many instances in which the GPU was causing problems for the game due to its power-saving capabilities and other settings. Set the GPU to the maximum performance can be done in this case.
  • Graphics Drivers Outdated: Graphics drivers are the most essential components to connect the game with the hardware. If they aren’t up-to-date or have issues with functioning, you may not be able to get the results you desire.
  • High Task Manager Priority In the event that the Fallout process is not a priority to your task manager the system does not view it as it’s a real-time game, and will delay in giving it large resources. Changes in the priority levels of the task manager can be done here.
  • Low specs for the Computer: This is the primary reason gamers experience slow performance within Fallout 4. If you’re running an unspecified computer and the game is not able to have the computational power it needs (obviously!) and may experience lagging when an event occurs or when the game enters a graphically intensive scene.
  • Poor BIOS settings We typically don’t suggest users to upgrade their BIOS because it could pose an increased risk, however we came across a lot of instances where completely resetting the BIOS resolved the problem. It could be due to issues with the settings stored within the BIOS.
  • bad mods When you use third party mods to your game, there’s an increased chance that they’re interfering with the game and creating problems when loading or displaying screens.

Before we begin with the solution, make sure you have an internet connection that is active on your laptop and you’re connected with the status of the administrator as well.

Fallout 4 typically includes an FPS cap in the configuration settings. The FPS cap is intended not to load your computer significantly. However, in our situation this setting could cause issues.
