You are enjoying your bumpy ride of being a Soviet KGB agent, have the most retro to advanced weaponry with futuristic technology, and suddenly your game stops.

It’s the Atomic Heart Low Level Fatal Error that puts a brake on your wild ride into the retrofuturistic world of the Soviet Union.

While that’s frustrating and is no less than a spoilsport, you would be looking for how to fix it as, just like the name, the error is fatal. Here’s where I have covered you all with effective solutions for their causes. 

How to Eliminate Atomic Heart Low-Level Fatal Error and Continue the Game Vibe?

The wholesome retrofuturistic world and the action, roleplay, and infinite thrill seem quite intriguing. However, when the peculiar Low Level Fatal Error in Atomic Heart obstructs the gameplay, fixing the error is essential. 

Thus, you can continue your gameplay and catch up with the gaming vibe without frustration.

Below-mentioned is how you can resolve it depending upon its causes! 

1. Check Device Compatibility 

One of the most unfortunate reasons for the Fatal error in PC gaming is when your device is incompatible with the game. 

Atomic Heart is designed to operate under a certain amount of resources; when these aren’t available, a group of errors can interrupt your game. Therefore, check if your system meets desired specifications or not.


Following is a list of Atomic Heart’s system requirements: 

  • Processor:  64-bit processor
  • OS: Windows 10 (20H1 version or newer, 64-bit versions)
  • Processor: AMD Ryzen 3 1200 or Intel Core i5-2500
  • Memory: 8 GB RAM
  • Graphics: 4 GB VRAM, AMD Radeon R9 380 or NVIDIA GeForce GTX 960
  • DirectX: Version 12
  • Storage: 90 GB available space
  • Additional Notes: 30 FPS, 1920×1080 in low

If your device meets these minimum system requirements, it’s compatible with the game. However, if not, you must upgrade your system with suitable hardware.

2. End Background Processes 

At a single time, multiple processes (both system and user) run in the background. Often these processes are in abundance, which consumes too many PC resources, thus making them unavailable for Atomic Heart. 

In such a scenario, you must end the background processes in your PC to eliminate the problem. 

  • Press the Win key and launch Task Manager from the menu that appears.
  • Expand the processes tab.
  • Navigate to the program you don’t need to run at the instant, right-click on it and select End process from the context menu.

Similarly, you can end all background processes, which you don’t need to run simultaneously with the game. This makes the system vacant, ensures smoother gameplay, and fixes the Atomic Heart Low Level Fatal Error. 

3. Restart your PC

When ending processes from the Task Manager doesn’t work, often temporary glitches for multiple reasons account for low-level Fatal errors.

Besides, sometimes your device also needs to connect to the internet properly. In either case, restarting the PC helps. 

  • Press the Win key and click on the Power-icon.
  • Select Restart from the context menu.

4. Verify the Integrity of Game Files

One of the most common reasons you are in the dark and didn’t get the gaming drill can be an issue with gaming files.

If they are corrupted or missing, you must repair them to troubleshoot them and resolve the low level Fatal error.

Gaming platforms nowadays let you directly verify the Integrity of gaming files like Steam, launchers, and Xbox. 

  • Go to Steam, navigate to library software, and hover over to Atomic Heart.
  • Right-click on Atomic Heart and choose Properties from the drop-down menu.
  • Select Local Files from the left pane and click on Verify Integrity of Game Files from the right.

Update AMD Driver

After downloading the latest version, you will no longer see the Atomic Heart Low Level Fatal Error. But if no update is available, the following methods will help. 

6. Let the Game Run on DirectX

Tweaking and forcing Atomic Heart to run on DirectX with a borderless fullscreen have fixed the problem for many users, including me. 

  • Go to Steam Library and navigate to Atomic Heart.
  • Right-click on the game and choose Properties.
  • Select General and navigate to Launch options.
  • In the empty box, type -dx12 and close the Window.

7. Update DirectX and Visual C++ Redistributables

DirectX helps the GPU and other gaming tasks to run efficiently on Windows. Besides, Visual C++ Redistributables are dynamic entities.


Both of them ensure a smooth gaming experience. However, if they are not updated, they lead to the Atomic Heart Low Level Fatal Error.

8. Disable Antivirus 

You would often use antivirus software to keep your device secure. However, these often obstruct you from diving into the world of Atomic Heart by giving the low level Fatal error.


Therefore, you must disable your antivirus and try again. If you can continue your gameplay in such a scenario, then the issue was with your antivirus, so add an exception, and you can then re-enable your antivirus.

You would tweak several features to enhance your experience with the Atomic Heart gaming experience and richly indulge in it.

These include enabling Vertical Sync, using Motion Blur, overclocking your PC, etc. However, these interrupt smooth gameplay, and thus you should disable them to fix the Fatal error. 

10. Disable Overlays 

There are several benefits of using in-game overlays, whether for gaming performance, resource utilization, that of your GPU, or more. Therefore, you must disable them to fix the error. 


Disable Steam Overlay

  • Go to Steam and click on Steam, found in the top-left corner.
