Run Battle Net as Admin

Call of Duty: Modern Warfare requires administrative access to perform certain functions and operations. By granting it the admin privileges, we might fix the error if it is behind the scene causing Dev Error 6068 to pop up.

  • Click on “Apply” and then “OK.”

To check if it works for you, reboot your computer and then launch Modern Warfare.

The VideoMemoryScale option allows us to change the amount of VRAM the game utilizes. As we know, Modern Warfare is a demanding game that uses resources heavily, so lowering down its VRAM value could be effective in resolving the error.

Prior to making any changes in the settings, open Task Manager and kill all the running processes related to Modern Warfare.

Disable Overlay apps: Deactivating overlay features such as Nvidia’s GeForce Experience, AMD Overlay, Game Bar, and Discord Overlay mainly helps in dealing with performance issues, including different gaming errors. So if you are currently using any of these overlay apps, try disabling them and see if that makes the Error 6068 go. 

Also, make sure to close any or all resource-eating apps that might be running in the background.


If you have tried all the methods given above, and nothing seems to go in your way as the Dev Error 6068 persists in Call of Duty: Modern Warfare, we advise you to seek Activision support. As a last resort, raising a support ticket should bring some clarity to your case.
