Dev Error 6068 Fix

According to Call of Duty Modern Warfare players, they are experiencing “Dev Error 6068 – DirectX encountered an unrecoverable error” while trying to play the game. To fix this error, make the following changes.

  • Turn off Nvidia overlay through Geforce experience
  • Set game to Windows borderless
  • Set refresh rate and FPS limit to match my monitors
  • Made sure you have latest Windows Update
  • Turn off GPU overclock and reverted back to stock clocks
  • Turn off XBOX Game Bar
  • Turn off RTX
  • Turned off MSI Afterburner and all other overlay apps
  • Set game to HIGH CPU PRIORITY on Task Manager
  • Set particles setting to Low

If you don’t like reducing the game’s settings then you can potentially resolve this issue by locking Call of Duty Modern Warfare at 30 FPS. Open Nvidia Control panel > Manage 3D Settings > Program Settings.

Select the game from the list and set vertical sync to “Adaptive Half Refresh Rate”. Apply the change, start the game and disable Vertical sync in-game and the game will be locked at 30 FPS. This will reduce the CPU and GPU usage resulting in stable performance.

Crash At Launch Fix

According to Players, when they start Call of duty Modern Warfare it just crashes at launch or doesn’t launch without any error. Here are a few fixes that might help you.

One reason for the game to crash at launch could be your anti-virus software or Windows Defender detecting the game’s exe as Trojan. Either disable your anti-virus software or make an exception for COD MW exe in your anti-virus software and the issue will be resolved.

If this doesn’t work for you, then the culprit might be third-party monitoring software like MSI Afterburner or GeForce Experience. Disable these and the game should work fine.

However, if you were using MSI Afterburner and disabling it hasn’t solved the issue then follow the steps below.

  • Open RivaTuner Statistics Server(RTSS).
  • Click the Add button and navigate to the game’s folder.
  • Add Call of Duty Modern Warfare’s exe under Application profile properties.
  • Set Application detection level to None for the game application.
  • Close RivaTuner Statistics Server.

100% CPU Usage Fix

To fix 100% CPU usage for COD Modern Warfare, go to “C:\Users\ YOUR NAME \Documents\Call of Duty Modern Warfare\players”.

Here you need to edit two files namely config.cfg and config-C7XXXXXX.cfg. Open these files and look for “setcl 895653276”. Now check that the resolution in front of this line is the same as your monitor’s display resolution.

If it’s set to a high resolution then change it to your monitor’s native resolution. Save it and run the game and the 100% CPU usage will be resolved.

If the set resolution is the same as your monitor’s native resolution, then you can try locking the game at 30 FPS to reduce the CPU usage. Open Nvidia Control panel > Manage 3D Settings > Program Settings.

Select the game from the list and set vertical sync to “Adaptive Half Refresh-Rate”. Apply the change, start the game and disable Vertical sync in-game and the game will be locked at 30 FPS.

Reportedly, COD Modern Warfare 2019 sets its priority to high by default which causes the CPU usage to increase. One potential fix for this is that start the game and then open Task Manager > Details tab. Right-click on the game’s process and set priority to “Normal”.

That is all for our Call of Duty Modern Warfare fixes for errors like Dev errors, crash at launch, Fatal Error, Dev Error 6071 and more.
