7 Ways To Fix Dev Error 6068 in Modern Warfare

Let’s take a look at some of the solutions so you can fix the issue and get back to your game:

Solution #1: Change the VideoMemoryScale

Modern Warfare uses a lot of the computer’s resources, and the VideoMemoryScale changes how much VRAM it needs. You will need to go into the system files to change this.

  1. Open the “Players” folder which is located at “Documents/CallofDutyModernWarfare
  2. Now look for a file called ‘adv_options.ini’ and run it using the Notepad app so you can change its values.
  3. Find the line saying “VideoMemoryScale
  4. The default is probably set to “0.85” so change it to “0.5” or “0.55“.

This will make the game use less VRAM than before, and might stop the error from happening. If not, try the next fix.

Solution #2: Use DirectX 11 to Force-Run the Game

DirectX 12 might be the most robust and newest gaming API but this doesn’t mean it won’t causes errors on occasion.

Some systems can give errors using DirectX 12 if they don’t have sufficient hardware or some of the update files are corrupted.

To solve this issue, you might like to try running the game on DirectX 11 instead and seeing whether that makes a difference.

  • Open the launcher, click on “Options” than click “Game Settings“.
  • When you see the dropdown menu find “Modern Warfare“.
  • Check the box saying “Additional Command Line Arguments“.
  • After that you will see a text box, type this in there: “-d3d11“.

Solution #3: Reduce Graphics Settings and End Background Tasks

Activision has not responded to comments that Dev Error 6068 occurs when the computer system is overloaded, but many players believe this is the case.

  • Go to the graphics settings (which is in the game’s Options) and lower the settings.
  • Try to put them on the lowest setting to see whether the graphics could be the reason for your issue.
  • Turn off “Ray Tracing” (even if your graphics card should be compatible) because it places a heavy load on your PC resources.
  • Switch off any applications running in the background, even browser tabs, using a lot of GPU or CPU.

Solution #4: Enable High-Performance Mode on Your Graphics Card

It can be hard to see the finer details when you’re in the middle of exciting gameplay, even though graphics cards are made to give players a top visual experience when playing games.

Making your card focus on giving the best performance rather than the best quality might help solve Dev Error 6068.

The process differs depending whether you have an AMD or NVIDIA card. Ensure your drivers are up to date, in case you have a driver bug causing the issue.

If you have an NVIDIA GPU:

  1. Open the NVIDIA control panel
  2. Go to “Adjust image settings with preview” and select “Use my preference emphasizing“.
  3. Move the slider left to improve performance (see image below).

If you have an AMD GPU:

  1. Open the AMD Radeon control center and choose “Preferences“.
  2. Click on “Radeon Additional Settings” and open the “Power” section.
  3. Now select “Switchable Graphics Global Settings“.
  4. Choose “High Performance” as your preferred setting and click on “Apply“.

Solution #5: Ensure You Don’t Have Corrupted Game Files

If you have tried all the above fixes and you are still experiencing Dev Error 6068, you might have corrupted in-game files. These can happen whenever you perform an update.

There are two ways of checking you don’t have corrupted in-game files. The first way is to completely uninstall then reinstall the game.

It is best not to delete all the game files that stay on your file after you perform the uninstallation.

This would take a long time though, since the game is so large, so perhaps try this fix first:

  1. Open the launcher and click on Modern Warfare
  2. Than click “Options” (next to “Redeem a Code“).
  3. Now open the dropdown menu, choose “Scan and Repair” and follow the on-screen prompts
  4. Any corrupted file should be replaced with a working file

Solution #6: Try a RAM Upgrade

Are you still having Dev Error 6068 even after trying the above five solutions?

In this case it could be that a RAM upgrade will help solve it, especially if you are using a RAM setup with frequencies under 3000 MHz. Try a RAM stick with a minimum of 3200 MHz frequencies.

This might not work, so you might like to borrow a friend’s RAM before spending money on your own, to see whether it works.

However, it’s fair to say upgrading your RAM is always a good investment since games tend to use more and more as the years go by.

Solution #7: Get in Touch with Activision Support

If you have tried all of the above fixes and you still get Dev Error 6068 then you might have to log a support ticket so the devs can figure out what is going wrong.

Their support helped me to fix Dev Error 6328 in past. They might ask for your error logs. You can also share the fixes you have tried so they can try others.


As you can see Modern Warfare “Dev Error 6068” is not that hard to fix. If you follow instructions mentioned above carefully, you should not have problem with fixing that.
