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.

  • 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.

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

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.
