How to Fix Dev Error 6068 in Call of Duty Modern Warfare

Bugs and errors are some of the most frustrating yet unavoidable aspects of gaming. Unfortunately, even triple-A titles with huge developer teams won’t be glitch-proof.

Dev Error 6068 is one of the most common errors plaguing Call of Duty players. The error may be caused by multiple things, including a corrupt DirectX installation, outdated or corrupt Windows files, outdated or corrupt drivers, and corrupt game files. 

So how can you fix it? 

Run the Game as Administrator

Launching Call of Duty with administrator privileges can solve error 6068 because certain files need admin access to run correctly. 

1. Open the Battle.net launcher. 
2. Open the Call of Duty page.

3. Click on Options, then Show in Explorer. 

4. Scroll down and find ModernWarfare.exe. 
5. Right-click the .exe file and select Run as administrator. 

6. Run Call of Duty as usual and see if the issue has been resolved. 

Optimize Graphics and CPU/GPU Usage

Dev Error 6068 can be caused by Call of Duty using too many system resources (especially if you’re using an older or sub-optimal set-up to play). Reducing the graphics settings may fix the issue by allowing your computer to run the game better. 

Lower Graphics Settings

1. Launch Call of Duty: Modern Warfare. 
2. Open Options and then Graphics. 

3. Set every option to the lowest setting. 

Problem Settings

Specific settings in Call of Duty: Modern Warfare appear to cause issues, including the Dev Error 6068. These include V-sync, ray tracing, crossplay, and g-sync. 

To disable these, follow these steps: 

For V-Sync:

1. Launch Call of Duty and open Options, then Graphics.
2. Scroll down to Sync Every Frame (V-Sync) and select Disabled.

For ray tracing:

3. Launch Call of Duty and open Options, then Graphics.
4. Scroll to Shadow & Lighting and disable DirectX Raytracing.

For crossplay:

1. Launch Call of Duty and switch to the Account tab. 
2. Select Crossplay and choose Disabled.

For G-Sync:

1. If you have an NVIDIA graphics card and G-Sync-compatible monitor, right-click the desktop and select NVIDIA Control Panel.
2. Expand the Display tab in the left-hand menu, then click on Set up G-Sync.
3. Uncheck Enable G-Sync.

Note: We recommend that you do each of these steps individually to see if it’s a particular setting that’s causing Dev Error 6068 for you.

Set the Call of Duty Process to High-Priority

Changing the Call of Duty application to a high-priority process can help if your PC isn’t handling the CPU and GPU load.

1. Ensure Call of Duty is closed.

1. Ensure Call of Duty is closed. 
2. Open the File Explorer.
3. You need to find the Call of Duty Modern Warfare “players” folder. This is usually found at:

Note: It may be on a different drive depending on your PC. 

4. Right-click adv_options.ini and select Open with then Notepad. 

5. Find the line that says VideoMemoryScale. 
6. Change the value of VideoMemoryScale to 0.5. 

7. Check if Dev Error 6068 is fixed. 

Force Run with DirectX 11

Many games do not run properly on the newer DirectX 12. This may be the case for Dev Error 6068. However, some games seem to run better using the previous version DirectX 11. To force Call of Duty to run with DirectX11, follow these steps. 

1. Open the Battle.net launcher. 
2. Select Options, then Game Settings.

3. Under Call of Duty: MW check the box for Additional command line arguments. 
4. In the textbox write -d3d11.

1. Start the Battle.net launcher and click Call of Duty: MW. 
2. Click Options and then Uninstall Game.

3. Once the uninstallation completes, restart your PC. 
4. Launch Battle.net again and select Install for Call of Duty: MW. 
5. Check if Dev Error 6068 is fixed. 

Run SFC and DISM Commands

Because the Modern Warfare Dev Error 6068 can be caused by corrupted or unstable Windows files, system repair tools can fix the error. These are the System File Checker (SFC) and the Deployment Image Servicing and Management (DISM) tools. Try running these tools to repair your Windows files, then restart the game. 

Check Your RAM

A common cause of Dev Error 6068 is incompatible or dysfunctional RAM. While it’s uncertain how your RAM can cause the issue, many users have claimed that installing newer RAM fixed their error. You can also diagnose and test your RAM to see if it’s functioning correctly. 

If nothing else in this article works, you may wish to consider upgrading your RAM. We recommend only doing this as a last resort. 

Back to the Gulag

Hopefully, one of these fixes solved your Dev Error 6068 problem, and you can get back in the game. If they did, consider sharing the solution with Activision and the COD: MW community as this will help others fix their game, too. 

If nothing worked, hopefully, the developers will work out the root cause of this error and release a patch that fixes it!
