How to Fix Fallout 4 Lagging
Fallout 4 is the 5th release in the Fallout series and is an open-world game which is based on a post-apocalyptic environment. The game is widely recognized in the gaming industry and is known for its intense graphics and extreme detail to objects and scenes.
Fallout 4 is all the way, a perfect game in every aspect. However, one error which was quite noticeable to users was where the game was lagging when playing. The game was either lagging continuously or there were frequent ‘spikes’ which hindered and ruined the gameplay. This is a very commonly occurring scenario and users all around the world face this issue every now and then without apparent cause.
In this article, we will go through all the different reasons as to why this issue occurs and what the possible solutions to fix it are.
What causing the Lagging in Fallout 4?
After receiving several user reports and conducting our own research, we came to the conclusion that the lagging in Fallout 4 was caused by several different reasons. Some of them are listed down below:
Note: Not all the causes might be applicable in your case. If you don’t find any which doesn’t match your scenario, don’t worry; just move on to the solutions and we will have the game up and running smoothly in no time.
- 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. Changing the settings work in this case.
- 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. Here, we can try diagnosing and closing all third-party applications running in the background.
- 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, lowering the settings or enabling the Windowed mode helps.
- 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. Setting the GPU to maximum performance works here.
- Outdated Graphics Drivers: Graphics drivers are the main components which communicate between the game and the hardware. If they themselves are not updated properly or are having issues in operation, you will not get the desired output.
- 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. Changing the priority level in the task manager works here.
- Low specifications of the Computer: This is the most common reason why users experience lagging in Fallout 4. If you have a low-spec computer, the game will not get its required computational power (obviously!) and will cause lagging whenever an event occurs or the game enters a graphics intensive scene.
- Bad BIOS configurations: We usually don’t recommend users to update their BIOS as it poses a risk but we came across quite a number of cases where resetting the BIOS completely fixed the issue. This might have to do with the configurations saved inside it.
- Bad mods: If you are using third-party mods in your game, there is a high chance that they are conflicting with the game and causing issues while displaying or loading screens.
Before we start with the solutions, make sure that you have an active internet connection on your computer and are logged in as an administrator as well.
Pre-requisite: Checking Requirements
Before you start anything, you should check whether your computer even meets the minimum specifications required by the game to function. If you don’t have the optimal requirements, you will indeed face stuttering and lag in game.
Here, it should be noted that you will not get a good FPS in minimum requirements. You should have at least the recommended or above-recommended requirements in order for everything to work smoothly.
Minimum Requirements OS: Windows 7/8/10 (64-bit OS required) Processor: Intel Core i5-2300 2.8 GHz/AMD Phenom II X4 945 3.0 GHz or equivalent Graphics Card: NVIDIA GTX 550 Ti 2GB/AMD Radeon HD 7870 2GB or equivalent Memory: 8 GB RAM Storage: 30 GB free HDD space
Recommended Requirements OS: Windows 7/8/10 (64-bit OS required) Processor: Intel Core i7 4790 3.6 GHz/AMD FX-9590 4.7 GHz or equivalent Graphics Card: NVIDIA GTX 780 3GB/AMD Radeon R9 290X 4GB or equivalent Memory: 8 GB RAM Storage: 30 GB free HDD space
If your system doesn’t fit in here, it is advised that you upgrade it in order to play without any lag or FPS drop.
Solution 1: Changing Settings of Graphics Card
The first thing to try is changing the settings of your graphics card so your graphics hardware provides all the necessary computational resources to the game. Usually, by default, all the games which you are playing are not set as a high priority in your graphics card. You have to manually navigate to the settings and after selecting the executable, grant it a high priority. In this solution, we will do exactly that.
Note: This solution is only for users who have a dedicated graphics card installed on their computer.
- Right-click anywhere on your screen and select NVIDIA Control Panel.
- Once in the control panel, navigate to Manage 3D settings and click on Program Settings.
- Once in program settings, select the OBS display capture. If you are not able to find the entry, click on Add and look up the game’s executable by navigating to its installation directory and selecting the executable from there.
Selecting Fallout 4 Executable - Now, select the option of High-performance NVIDIA processor under the settings of the preferred graphics processor.
Changing Preference to Dedicated graphics - Save changes and exit. Now restart your computer and launch Fallout 4 again. Check if the issue is resolved and you have a stable game.
Solution 2: Lowering in-game Graphics
Another thing to try before we jump into other technical solutions to lower the in-game default graphics settings stored inside your game. Usually, the game has high to medium graphics settings active. Here in this solution, we will navigate to options of the game and manually lower all the settings so you can have a little less detail but a lot more stability when playing. Make sure that you follow each step carefully.
- Launch Fallout 4 on your computer and start its launcher. Then, click on Options from the main screen.
Options – Fallout 4 - Next, you can either select Low details or click on Advanced and change the settings manually. Try to get things out of ultra and change them to Medium or Low.
Reducing Fallout 4 Graphics - After making changes, click on OK and save changes. Restart the launcher of Fallout 4 and start the game. Check if the issue is resolved.
Important: You should also consider launching the game in Windowed mode with Borderless. This reduces the lag a lot.
Note: You can also try lowering the resolution and after navigating to the Display settings on Windows, reduce the refresh rate as well.
Solution 3: Removing the FPS Cap
Fallout 4 usually has an FPS cap present in its configuration settings. This FPS cap is meant not to overburden your computer a lot. However, in our case, this setting might be causing issues. Even though the FPS cap is set to a decent amount in which the game doesn’t lag at all, we found several cases where this wasn’t true and the settings were causing issues with the running of the game. In this solution, we will navigate to the configuration files of Fallout 4 and change the setting manually by editing it. Make sure you are logged in as an administrator.
- Press Windows + E to launch the File Explorer and navigate to the following file path:
C:\Users\<username>\Documents\My Games\Fallout4
- Now, locate the following file. Right-click on it and select Open with > Notepad (you can also use other software such as Notepad++).
Fallout4Prefs.ini
- Press Windows + F to launch the finder and locate the ‘iPresentInterval’ string.
Changing iPresentInterval - Change its value from 1 to 0. Save changes and exit. Restart your computer completely and then launch the game again. Now check if the issue is resolved and you are able to play the game lag free.
Solution 4: Checking Third-Party Application and Changing Priority
Another thing which we can try before we dive right into the graphics drivers and BIOS settings is making sure there are no third-party applications running in the background which are consuming resources. We usually ignore this scenario but if a third-party application (which is resource extensive) is running in the background, it will obviously keep the CPU/graphics hardware busy. This effect will propagate to the game as well and it will start lagging or stuttering in-game.
Furthermore, we will also change the priority of the game so the computer prioritizes Fallout 4’s process and grants it all the resources it needs.
- Press Windows + R, type “taskmgr” in the dialogue box and press Enter.
- Once in the task manager, look at all the processes running in the background. Look for any process which you might think be consuming resources. Right-click on it and select End Task.
Ending third-party programs - Now try launching Fallout 4 again and see if the lag issue is fixed for good.
If this doesn’t solve the problem and you still having delay and lagging in the game, follow the steps below to make it a priority in the task manager.
- Open the task manager again as we did in the previous step and navigate to the tab of processes.
- Now, locate Fallout 4 from the list, right-click it and select Set Priority > Real-time (or High).
- After making changes, switch back to the game and check if the lagging fixed.
Solution 5: Disabling Mods
Mods form a very important component in the Fallout 4 experience and there are loads of them available on the internet. It allows players to improve the overall gameplay by adding custom content and textures in the game. Despite mods giving players a whole new experience, they are notorious for conflicting with the in-game mechanics and cause several issues. Since they are directly interacting with the game’s core, they are bound to conflict every now and then.
Furthermore, if the mods and the game’s version are not in-sync, the game will behave in a bizarre way and even crash on numerous occasions. Hence, you should try disabling all the mods running on your computer. Consider copy-pasting the mod content to another location until we complete the troubleshooting process. After removing the mods, restart your computer and check if the issue is resolved.
Solution 6: Updating Graphics Drivers
If all the above methods don’t work, there is a possibility that you don’t have correct graphics drivers installed on your computer. Drivers are the main components which facilitate the interaction between the game and the hardware. If the drivers are outdated or corrupt, the game might not display correctly and cause lagging. In this solution, we will first remove the current drivers using DDU and then install fresh copies.
- Download and install DDU (Display driver uninstaller) from its official website.
- After installing Display Driver Uninstaller (DDU), launch your computer in safe mode. You can check our article on how to boot your computer into safe mode.
- After launching the DDU, select the first option “Clean and restart”. This will uninstall the current drivers completely from your computer.
- Now after the uninstallation, boot your computer normally without safe mode. Press Windows + R, type “devmgmt.msc” in the dialogue box and press Enter. Right-click on any empty space and select “Search for hardware changes”. The default drivers will be installed. Try launching the game and check if this solves the problem.
- In the majority of the cases, the default drivers will not work for you so you can either install the latest drivers through Windows update or navigate to your manufacturer’s website and download the latest ones.
- After you have installed the drivers, restart your computer and check if the problem is solved.
Note: Also consider uninstalling NVIDIA GeForce Experience from your computer. This is known to cause issues.
Solution 7: Updating your BIOS
BIOS (also known as Basic Input/Output System) is the main firmware of your computer. BIOS is preinstalled on all Windows computers and it, in turn, handles all the inputs/outputs from your computer. The OS loads on top of this firmware and it is considered the backbone of every computer.
Quite surprisingly, we received several reports that updating the BIOS to the latest version solved the problem for the majority of the people. We usually don’t encourage users to update their BIOS as the update process poses a risk of bricking the computer but due to the number of positive responses, we decided to keep it as a solution.
Here, we recommend that you either take your computer to a computer expert or backup your data completely before following the mentioned articles below to update your BIOS.
Note: Please proceed at your own risk. Please read all the instructions carefully as not doing so might make your computer unusable.
