How do I fix the Memory overrun error in Monster Hunter: World?

1. Make sure you’re meeting system requirements

To begin, make sure your computer meets Monster Hunter: World’s system requirements. In many ways, this Capcom game is fantastic; however, most bad feedback comes from gamers who are having difficulty playing with friends (server difficulties) or are suffering frequent crashes.

As a result, Steam ratings are mediocre. However, before blaming coders, let’s be sure the fault isn’t on our end.

8 GB of RAM is required for both the minimum and recommended system requirements. However, because the game is known to be memory intensive, 8 GB of RAM will be insufficient. Especially if you use screen recording or voice chat software in the background.

The following are Monster Hunter: World’s minimum and recommended system requirements.


CPU: Intel Core i5-4460, 3.20GHz or AMD FX-6300
OS: WINDOWS 7, 8, 8.1, 10 (64-bit required)
GPU: NVIDIA GeForce GTX 760 or AMD Radeon R7 260x (VRAM 2GB) Shaders: 5.0
HDD: 20 GB of storage space


CPU: Intel Core i7 3770 3.4GHz or Intel Core i3 8350 4GHz or AMD Ryzen 5 1500X
OS: WINDOWS 7, 8, 8.1, 10 (64-bit required)
GPU: NVIDIA GeForce GTX 1060 (VRAM 3GB) or AMD Radeon RX 570X (VRAM 4GB) Shader: 5.1
HDD: 20 GB of storage space

2. Reinstall GPU drivers

    1. Right-click Start and select Device Manager (Windows 7/8/8.1 users can also use Windows Search).
    2. The Display Adapters section should be expanded.
    3. Choose Update device from the contextual menu when you right-click on your GPU.
    4. If no updates are available, right-click again and select Uninstall device.
    5. Restart your computer and try again.

In Monster Hunter: World, insufficient GPU drivers are the most typical cause of memory problems. The issue appears to be widespread, affecting primarily Nvidia graphics processors.

That doesn’t rule out the possibility of ATI users experiencing frequent crashes and the Memory overrun fatal error.

The first step is to run a basic driver update through Device Manager. If it doesn’t work, you can reinstall the GPU driver in the same way.

If you have a dual-GPU platform with integrated and dedicated cards, disable the integrated card before trying to launch the game.

3. Increase Virtual memory size

Allocate Virtual Memory

    1. Type Advanced into the Windows Search box and select View advanced system settings.
    2. From the dialog box, select the Advanced tab.
    3. Select Settings from the Performance section.
    4. Select Advanced.
    5. Opt for Virtual Memory.
    6. Uncheck the box for Manage paging file size for all disks automatically.
    7. Select Custom size and enter the MB values for your current physical RAM.
    8. Reboot after you’ve confirmed the modifications.

Disable Paging file

    1. Type Advanced into the Windows Search box and hit Enter. View the system’s advanced settings.
    2. From the dialog box, select the Advanced tab.
    3. Select Settings from the Performance section.
    4. Choose Advanced.
    5. Activate Virtual Memory.
    6. Uncheck the box for Manage paging file size for all disks automatically.
    7. Click the Set button after selecting No paging file.
    8. Reboot after you’ve confirmed the modifications.

As previously stated, the game has experienced memory leaking concerns since the beginning. Even though Capcom reduced the issue with a few upgrades, it is still wreaking havoc on specific setups.

Memory leaking or inconsistent memory freeing results in massive VRAM utilization. And, because the VRAM is limited by default, the game or the entire system may crash or freeze on occasion.

When it comes to virtual memory distribution, you have two options. Try them out and see where you can make changes.

4. Disable background processes

    1. Type msconfig into the Windows Search bar to access System Configuration.
    2. Check the Hide all Microsoft services option under the Services tab.
    3. To disable all active third-party services, click Disable all.
    4. Go to Task Manager and pick the Startup tab.
    5. Stop all programs from starting up with the system, and double-check your adjustments.
    6. Restart your computer.

The readings in Task Manager for impacted users are absurd. Extremely high RAM utilization, resulting in total depletion and subsequent crashes. To be sure, they’re frequent.

But what more can we say when we know that some of those customers have 16 GB of RAM and are still experiencing problems? Nothing major, except attempting to lessen all other infractions. And we’re talking about background apps here.

If you don’t need them, turn them off and let the game be the only thing that runs on Windows.

A clean boot process that disables any non-Microsoft services from starting with the system is the best method to ensure everything is disabled.

You can also go to Task Manager and terminate all background apps. Some users reported that disabling/uninstalling the Duet Display application fixed the problem, so try that.

5. Update the game

We also mentioned that Monster Hunter: World received frequent updates that reportedly addressed these and other issues. A few patches helped to fix the game’s optimization concerns.

The astonishing fact is that consumers had trouble attaining adequate FPS on top-of-the-line GPUs before the revisions.

As a result, wait for updates, and you should notice some performance improvements as soon as they are applied. This is, of course, done automatically, and all you have to do is make sure your connection is stable.

Put some pressure on the developer and hope for the best if there isn’t a fix right now. In the meantime, we’ll need to rule out any possible involvement on our part, so try the final two steps as well.

6. Verify game files

    1. Launch the Steam Library.
    2. Open the Properties menu by right-clicking on Monster Hunter: World.
    3. The LOCAL FILES tab should be selected.
    4. Select the option to VERIFY THE INTEGRITY OF GAME FILES.
    5. Start the game from the Steam desktop client after restarting your computer.

Let’s try to validate the game files using the Steam client before moving on to the reinstallation step. The game will normally be totally shut down if the data are corrupted, although it may also cause some unexpected problems.

We can’t state that this is a remedy for the Memory overrun fatal issue, but it is a typical solution for Steam-based games in general.

After completing the integrity check, go to the drive where Steam and the individual games are installed.

Using a text editor, open the graphics option presets.ini file. Save the changes after changing the PresetCount value from 4 to 0. The graphics options.ini configuration file should be treated similarly.

7. Reinstall the game

    1. Launch the Steam Library.
    2. Uninstall Monster Hunter: World by right-clicking on it.
    3. Delete all files in the steamapps folder that remain.
    4. Return to Steam and download the game.

Finally, if none of the preceding procedures worked, the only option is to reinstall the game. We virtually cover everything (or at least the most of it) that can go wrong on your end with this.

If the Memory overrun fatal error persists, it is entirely due to Capcom or Nvidia/ATI and not your problem.

You may, of course, reinstall the operating system, but this won’t help much because the problem isn’t your fault.
