How to Troubleshoot and Fix Call of Duty Dev Error 6068

The Dev Error 6068 in Call of Duty (any variant) can be caused by a corrupt DirectX installation on your System. It can also be caused by an outdated Windows, System Drivers, and non-optimal settings for the game.

The Dev Error 6068 in the game accounts for freezing/crashing of the game with the following message:

The Dev Error 6068

According to our research, it seems that the issue is mostly related to software aspects of the computer system used to play Call of Duty with very less likelihood of a hardware problem. Here are a few common remedies to be looked into before you proceed with the specific solutions:

  • If you are using multiple displays, then use only one display.
  • Make sure if all other games are working fine.
  • To run optimally, the game requires RAM speeds of 3000 MHz, so, make sure your system meets the requirement.
  • Make sure you have a stable and fast internet speed.

Run the Game as Administrator

Call of Duty requires admin privileges to access certain files and services. And if it is not given admin privileges, then it can result in the Dev error 6068. In that case, launching the game with administrative privileges may solve the problem. For illustration, we will discuss the process for Battle.net launcher. And to run Call of Duty as an administrator, you may follow instructions specific to your platform.

  1. Open the Battle.net launcher and open the Call of Duty window.

    Run the Call of Duty as Administrator

Set the Priority of Call of Duty’s Process to High

Although, it is not a good idea to play with the priorities of the process if you do not know what you are doing, but in the current scenario as the game loads your CPU & GPU quite heavily, changing the priority of its process to High Priority may solve the problem.

  1. Right-click on the Task Bar and then click on the Task Manager.
    Open Task Manager
  2. Now find and right-click the process of the Call of Duty and then in the menu, click on Go to Details.

  3. Now change the value of VideoMemoryScale to 0.5.
  4. Then launch the Call of Duty and check if the problem is solved.

Deactivate Game Overlay/Performance Monitoring Application

Programs with overlay features are known to be the cause of many Dev Error codes including the Dev Error 6068. Some of these programs are Nvidia’s GeForce Experience, AMD Overlay, Game Bar, and Discord Overlay. Moreover, performance monitoring software applications like MSI Afterburn are also known to cause the Dev Error 6068. If you are using any such software applications, then disabling the application may solve the problem.

If you are using any other overlay or performance monitoring application, then follow instructions specific to that particular application to disable it and check if the Call of Duty is operating fine.

Use DirectX 11 for Call of Duty

DirectX 12 is the newly adapted API for gaming. But many games encounter different types of issues when using the DirectX 12. If that is the reason for your issue, then changing the arguments of the game to use the DirectX 11 which can fix the DirectX error on the Call of Duty and thus may solve the problem.

  1. Clean boot your system.
  2. Now launch Call of Duty as administrator (make sure no other application is running) and check if the problem is solved.
  3. If so, then try to find the problematic application and solve the issue between the applications.

Tweaking the Shaders

Call of Duty uses Shaders for showing shades in 3D scenes. However, Shaders are known to cause many Dev Errors including the Dev Error 6068. The problem with the Shaders is that they are forced by the developer and you cannot just simply disable it. There are two workarounds (till the final fix arrives).

Reinstall Shaders

  1. Launch the Call of Duty and start playing.
  2. When in-game, start the reinstallation of the Shaders.
  3. Keep playing the game until it is installing. If the installation of Shaders is complete during the process, restart the installation process. Keep reinstalling the Shaders whenever the installation completes till you are playing the game.

Delete the Players/Players 2 folder

Deleting these folders will delete shaders out of your game.

  1. Exit the Call of Duty and kill all its running processes.
  2. Now navigate to the players folder of the Call of Duty. Usually, it is located at:
Documents\Call of Duty Modern Warfare\
  1. Backup the Players folder, just in case! or if there is Players 2 folder, backup it as well.
  2. Now delete the Players folder. Or if there is Players 2 folder, delete it as well.
    Backup and Delete Players Folder
  3. Now launch the Call of Duty and check if the problem is solved.

  3. Now uncheck the option of Enable G-Sync and check if the problem is solved.
    Disable G-Sync

Reinstall DirectX

Microsoft DirectX is the API used by software applications to communicate with the computer’s hardware. If it has corrupted (which can be as the error message is indicating that something is not right with the DirectX), then it can be the reason for the current issue. In that case, reinstalling it may solve the problem.

  1. Reinstall DirectX.
  2. After reinstallation of the DirectX, check if the game has started to operate fine.

Disable Overclocking of CPU/GPU

Overclocking is a common norm in the gaming world but it is known to create a lot of issues for the games. Overclocking your CPU/GPU could be the root cause of The Dev Error 6068. In that case, reducing the clock speed or resetting your CPU/GPU to its stock speeds may solve the problem.

  1. Lower your clock speed. You should study the mechanics of Overclocking before attempting to lower the clock speed.
  2. After lowering the clock speed of your CPU/GPU, check if the game is working fine.

Run the SFC and DISM Commands

Corrupted OS files especially related to DirectX can lead to the Call of Duty Dev Error 6068. But fortunately, we have built-in utilities that can solve the issue of corruption of the system files. In that case, running these commands may solve our problem

  1. Run the SFC
  2. Run the DISM
  3. Then launch Call of Duty and check if the problem is solved.

Reinstall the Game

If nothing has worked you so far, then it is time to uninstall the game and then reinstall it. For illustration, we will discuss the process for Battle.net launcher.

  1. Launch the Battle.net launcher and click on the icon for the Call of Duty.
  2. Then click on the uninstall Game button.
    Uninstall Call of Duty
  3. Now follow the on-screen instructions to complete the uninstallation process.
  4. Then restart your system.
  5. Now launch the Battle.net launcher.
  6. Then install the Call of Duty and check if the problem is solved.

Enabling XMP for your RAM (if applicable)

If none of the methods shown above worked for you it’s highly possible that your RAM is clocked down and being bottle-necked by your BIOS settings. If your RAM supports XMP and you have an option for it in your BIOS settings we highly recommend you to enable XMP to get the best possible clocks out of your RAMs. You can learn more about how to enable XMP here.

Reset or Clean Install Windows

If nothing has worked for you so far, then you are left with no other option but to either reset the Windows or perform a clean installation of Windows.

Change RAM

It is possible that sometimes the RAM that you have installed on your computer is preventing you from being able to play this game. Therefore, if you have any extra RAM sticks lying around or if you are willing to try out new RAM on your computer, try changing the RAM on your computer.

Lower FOV:

Some users experienced that when they lower the FOV below 100 and around 95, they are able to play the game perfectly without getting the Dev error. Therefore, it is recommended to keep the graphics settings at default and to lower the FOV to around 95.
