Call of Duty: Modern Warfare “dev error 6068” explained

Call of Duty: Modern Warfare “dev error 6068” explained

Even if the most advanced programmers and game designers collaborated on a title, it would still be almost impossible for players not to run into bugs or errors at least once. Triple-A games give the impression like they may be glitch-proof, but they also go through the same struggles that indie games have to endure.

Call of Duty: Modern Warfare players can be accustomed to server-related problems that occasionally pop up during double XP weekends, but fundamental errors without proper explanations can be quite the scare. This kind of error usually prevents players from launching the game, and the solutions you'll need to try will require you to roam around the game's files.

The dev error 6068 usually appears right after players click on "Play" through Battle.net or after 10 minutes into the gameplay. It sends them back to their desktop, and Modern Warfare stops responding and shuts itself down in the meantime. While some users report that the issue fixes itself after updating your GPU's and PC's drivers to the most up-to-date versions, the error can also linger on.

How to fix the "dev error 6068" in Call of Duty: Modern Warfare

If you've made sure that all of your drivers are updated, then the cause of this error may be lying inside the game's files.

While the cause of this error is known, most of the fixes indicate that it can be tied to a memory-related issue.

Here are all the methods you can try to fix the "dev error 6068."

Change the VideoMemoryScale value inside game folders

Modern Warfare is a demanding game when it comes to resources. The VideoMemoryScale option alters how much VRAM the game needs, and the only way to change it is through the system files.

Open the "players" folder, which will be located over at "Documents/Call of Duty Modern Warfare."

You'll need to look for a file named "adv_options.ini." Run this file with the notepad application so you'll be able to alter the values inside. Locate the line that reads "VideoMemoryScale" and change it to 0.5 or 0.55. The default should be 0.85.


You'll notice that Modern Warfare will start using a lot less VRAM than usual after implementing this change, and it will give your system some breathing room.


Force run the game with DirectX 11


DirectX 12 is the latest and the most robust API for gaming, but the news may not always be better. Some systems can still run into errors with DirectX 12 due to corrupted update files or just insufficient hardware.


You can get around this issue by forcing Modern Warfare to run on DirectX 11.

  • Open up the Battle.Net launcher.

  • Click on Options, which should be located toward the top left of the launcher.

  • You'll need to click on "Game Settings" from the dropdown menu.

  • Once you get into "Game Settings" find Modern Warfare and put a checkmark on "Additional command-line arguments."

  • A text box will appear just below it. Type "-d3d11" in there without the quotation marks.

If you have been receiving the error right after launching the game, then this fix should at least get you to the main menu.
