Verify Integrity Of Game Files

The most well-known issue that players come across when they encounter the Ark low-level fatal error is corrupted or missing game files during the installation/ downloading of the game. So, you have to just simply re-download the missing game files or corrupted files by simply verifying the integrity of the game files.

Here’s a guide to help you verify your game files if you don’t know how to.

Reduce In-Game Graphics

If you are playing Ark Survival on a lower-end system, then you might be encountering the Ark low-level fatal error due to running a game that is very demanding for your system to handle. Lowering your graphics settings will ensure that your system can handle Ark survival and does not crash due to having a weaker gaming system. You can easily reduce the in-game settings by following these simple steps.

  1. Launch Ark Survival Evolved on Steam or Epic Games launcher>Go to settings>Select the graphics quality option and change the graphics quality to low.

Disable Overlays

Overlays are widely known as problematic in the gaming community as they are famously known to cause major issues like stuttering, crashing, and freezing despite offering various useful features during gaming. Several gaming overlays may cause your game to run into low-level fatal errors, and it is absolutely necessary to disable these overlays in order to ensure that you are not encountering low-level fatal errors in Ark due to a gaming overlay.

Here are all the methods required to disable the most used overlays on pc.

Disable The Nvidia Game Optimization

Another commonly reported issue among the players is that using the game optimization feature leads to a low-level fatal error. Nvidia GeForce Experience has, by default, enabled the option to optimize newly installed/added games into your PC by tweaking the game files and settings.

  1. Open the Nvidia GeForce Experience>click the settings icon on the top right side of the window beside the account name.

Precaution: Doing this will also disable any optimizations made by NVIDIA to all of your other games as well.

Modded Content

Several cases have also surfaced in which players have reported that due to the presence of some mods, the game has been known to give low-level fatal error. So, ensure that you have all the mods removed the next time you launch the game to see if the problem originates from the mods applied to the game. If the issue turns out to be the mods installed on your PC, then you may have to troubleshoot the exact mod that is triggering the error.

Rendering Issues

Another issue players encounter regularly is crashes due to compatibility problems with the rendering mode of the game. By running the game on DirectX 11, you may constantly experience crashes due to your graphic card experiencing hardware or software issues. Your best bet would be to try running the game on an older rendering API like DirectX 10. If your game runs successfully on older API, then it means that it’s specifically a problem relating to your drivers or the game settings. Here is how you change your rendering API to DirectX 10.

  1. When you are trying to launch the game, a window will pop up.
  2. From the list of launch options, select Launch Ark “(Direct X 10, low-end graphics).”
  3. Alternatively, you can also choose the different launch options to see if it fixes the issue.

Update your Drivers

If your game is encountering the “runtime Direct 3d device is being lost” error while running into a low-level fatal error, then your graphics card is crashing due to, most likely, a software issue. The easiest method to fix this issue is to update your graphics driver to the latest version, or in case updating doesn’t work, re-install your graphics driver to see if the issue is fixed.

Here is a guide on how to update your drivers that we’ve already.

Re-installing the Game

If you have successfully applied all the methods listed above and have not seen any improvement in solving the ark low-level fatal error, then it is most likely a result of a faulty game that you are encountering a low-level fatal error. Hence, you have to simply uninstall and re-install the whole game from scratch.

My Thoughts

Even after being one of the popular survival featuring tech and prehistoric elements with stunning graphics, It still suffers from certain issues and setbacks that must be fixed. I hope the devs are actively working on it. However, until these issues are officially fixed permanently by the devs, this guide will be your best workaround to keep you going in your Ark Adventure.
