#1 Try Running Other Games

It may also possible that the PC hardware or software has some serious issues. So, it’s better to try running other online games on your computer to check whether there are any errors appearing or not.

#2 Check your RAM Frequency

It looks like the COD Warzone game basically requires around 3000MHz RAM frequency to run it properly or smoothly. So, make sure that your PC configuration is meeting the system requirements of the game. If not, that can be another reason behind such an error.

#3 Change Video Memory Scale

You’ll need to change the Video Memory Scale on your PC. To do so:

  • Close the COD Modern Warfare game > Open File Explorer.
  • Navigate to the Documents\Call of Duty Modern Warfare\players path. [If you’ve installed your game to another drive, navigate there]
  • Look for adv_options.ini file and edit in Notepad.
  • Now, find out the VideoMemoryScale line > Change the value of VideoMemoryScale to 0.5.
  • Save the changes and try running the game again to check for the issue.

#4 Use a Stable Internet Connection

It seems that maybe your internet connection isn’t stable enough to hold the nerves while connecting to the game server during peak hours. Make sure that your internet connection is stable and fast enough. You can also try changing the wireless (Wi-Fi) connection to a wired (Ethernet) connection for a stable signal. Otherwise, try increasing the internet speed by upgrading to a higher data plan or fiber connection.

Most importantly, try force closing all the unnecessary or higher CPU/Memory usage background running processes like browser, startup programs, overlay applications, any cloud service, etc.

  • Press Ctrl + Shift + Esc keys to open Task Manager.
  • Click on the Processes tab > Click to select your task that you want to close.
  • Now, click on End Task to close it.
  • Do the same steps for each and every task that you want to close.

#6 Use PC Screen Only Option

If in case, you’re using multiple screens that are connected to your computer, make sure to use the single PC screen only.

  • Make sure to exit the Call of Duty Modern Warfare game.
  • Go to Task Manager and close all the COD processes which are running in the background.
  • Now, click on the Notification icon from the System Tray of the Taskbar.
  • Click on Project > Choose PC Screen only.
  • Finally, try running the game again.

#7 Run the Game as an Administrator

Sometimes it can possible that your game files don’t have admin access in order to run it properly on your Windows system. Try to run the game as an administrator first. To do this:

  • Launch the Battle.net client > Open Call of Duty Modern Warfare.
  • Click on Options > Select Show in Explorer.
  • The Modern Warfare installed folder will open.
  • Find and right-click on the executable file and select Run as administrator.
  • If prompted by UAC (User Account Control), click on Yes to allow the permission.

  • Launch the Battle.net client > Click on Call of Duty Modern Warfare.
  • Click on Options > Select Scan and Repair.
  • Choose Begin Scan.
  • Wait for the scanning process to complete.
  • Once done, restart your PC and run the game.

#9 Use Additional Command Line Arguments

A corrupted DirectX installation can also cause issues with the game. Reinstall DirectX directly from the Microsoft official site. Additionally, you can use the command line argument field to forcefully use DirectX 11 for your games.

  • Open Battle.net client > Click on Modern Warfare.
  • Select Options > Choose Game Settings.
  • Click on the Additional Command Line Arguments checkbox to enable it.
  • Now, type -d3d11 in the input field and save changes to forcefully use DirectX 11.
  • Finally, restart your Battle.net client and run the Warzone game again.

#11 Reinstall Shader Files

  • Try reinstalling the Shaders file during the Warzone gameplay. Don’t exit the game. Make sure to fully reinstall Shaders during the gameplay. Once done, restart your Battle.net client and check for the issue.
  • Try to delete the Players/Players 2 folder from Documents\Call of Duty Modern Warfare\ location on your PC. Make sure not to permanently delete the file. Simply select the file and press Delete only to move it to Recycle Bin (If anything goes wrong, you can get back your file). Once done, launch the game.

#12 Turn Off V-Sync and G-Sync

#15 Run System File Checker

Whenever any program on your Windows system starts lagging or crashing or may not performing unexpectedly, make sure to run the system file checker (SFC) scan to know more if there is any bad sector or errors present in the hard drive. You’ll have to run the SFC scan using the command prompt.

  • Click on the Start menu > Type CMD.
  • Now, right-click on the Command Prompt > Select Run as administrator.
  • If prompted by UAC, click on Yes > Type the following command and hit Enter to execute:
sfc /scannow
  • You may have to wait for some time to complete the scanning process.
  • If there is any visible error available, try to fix it.

#16 Reinstall Modern Warfare/Warzone

If none of the methods worked for you, try reinstalling the game again on your computer. To do that:

  • Launch the Battle.net (Blizzard) client > Head over to the Game Library.
  • Click on the Call of Duty: Modern Warfare.
  • Click on Options > Select Uninstall Game.
  • Once the game is removed, restart your computer.
  • Now, open the Battle.net client again and download/install the COD Modern Warfare again.

This should definitely fix the Dev Error 6068 in COD Warzone.

Fix Dev Error 6165

This error appears when the players ty loading multiple screens for multiplayer mode or try opening the cut scene for single-player mode. Players encounter this error code 6065 in Call of Duty WarZone because of the latest GPU drivers. In this case, they can roll back to the older GPU drivers’ version, and the problem will be resolved.

However, make sure to check for the latest graphics driver update at first if any update is pending, then try to install the update and check whether the Dev Error 6165 has been fixed or not.

3. Reinstall Modern Warfare/Warzone

Otherwise, you can try uninstalling and reinstalling the game again. To do this:

  • Launch the Battle.net (Blizzard) client > Head over to the Game Library.
  • Click on the Call of Duty: Modern Warfare.
  • Click on Uninstall Game from the Options category.
  • Once the game is removed, restart your computer.
  • Now, open the Battle.net client again and download/install the COD Modern Warfare again.

Fix Dev Error 6066

Both the COD Dev Error 6065 and 6066 can happen due to the GPU problems. Infinity Ward has suggested some of the possible workarounds that are mentioned below:

1. Run VRAM at Maximum

Here are the steps to find out the VRAM available.

  • Press the Windows + I keys to open up the Windows Settings menu.
  • Click on System > Under the Display section, click on Advanced display settings.
  • At the bottom of the page, click on Display adapter properties for Display 1.

  • Select Pre-Allocated VRAM and change the existing value, which by default will be 64M or 128M. Change it to 512M.

2. Force the Game to Start with DirectX 11

  • Open Battle.Net Client on the PC.
  • Open the game COD Modern Warfare.
  • Go to Options
  • Check Additional Command Line Arguments and type -d3d11
  • Exit and try playing the game. Check if the Call of Duty Warzone Dev Error 6065 & 6066 still appears. If it does, move to the next fix.

3. Restore GPU Defaults

Whether you’re using Nvidia or MSI or AMD GPU card, you should restore the clock speed to its default via the MSI Afterburner tool or Zotac firestorm application. Using the default clock speed will ensure the optimal performance of the GPU and increases longevity.

  • Launch the Nvidia GeForce Experience app.
  • Click on the Settings icon (gear) > Under Features, click on General > Disable IN-GAME OVERLAY.

5. Disable Other Overlay Apps

Like the Nvidia GeForce Experience overlay app, some other overlay applications present in the market that most PC users or gamers use. Such as Xbox Game Bar, Discord Overlay, Steam Overlay, etc. So, as a PC gamer, if you’re using Steam or Game Bar or Discord overlay, make sure to temporarily turn them off and try running the Modern Warfare or Warzone game to check if the Dev Error 6066 is fixed or not.

6. Update Windows OS Build

  • Click on Start > Choose Settings > Select Update & Security.
  • Click on Check for updates. If any update is available, simply Download and Install it.
  • Once done, the system will ask you to restart your computer to apply changes.

7. Set Higher Priority

If the issue still persists, then try to set the Higher CPU Priority for the Call of Duty Modern Warfare game from the Task Manager.

  • Press Ctrl + Shift + Esc keys to open Task Manager.
  • Now, go to the Details tab > Scroll down and locate the COD Modern Warfare.
  • Then right-click on the task and hover over the Set Priority.
  • Select High from the drop-down list and save changes.
  • Once done, close Task Manager, and run the game again to check whether the issue has been fixed or not.

8. Use PC Screen Only Option

If in case, you’re using multiple screens that are connected to your computer, make sure to use the single PC screen only.

  • Make sure to exit the Call of Duty Modern Warfare game.
  • Go to Task Manager and close all the COD processes which are running in the background.
  • Now, click on the Notification icon from the System Tray of the Taskbar.
  • Click on Project > Choose PC Screen only.
  • Finally, try running the game again.

9. Disable RTX (Ray Tracing)

Call of Duty Modern Warfare only has a single setting for its ray tracing support. Go to the in-game Settings > Head over to Graphics > Under the Shadow & Lighting option, Disable DirectX Raytracing.

10. Reinstall DirectX

As DirectX is one of the most important parts for the Windows operating system to run apps or games smoothly, we’ll highly recommend you to update your Windows to its latest version & build. Once done, you can try reinstalling the DirectX version via the DirectX Installer from the official Microsoft website.

11. Scan and Repair Game Files

If your game files are somehow missing or corrupted then make sure to verify and repair the game files properly by using the Battle.net client.

  • Launch the Battle.net client > Click on Call of Duty Modern Warfare.
  • Click on Options > Select Scan and Repair.
  • Choose Begin Scan.
  • Wait for the scanning process to complete.
  • Once done, restart your PC and run the game.

12. Disable Crossplay

Now, you can try again to run the game whether it’s working or not.

14. Check Internet Connection

Sometimes poor internet connection causes dev errors. Check and refresh your internet connection. This seems small, but it may become the main reason for errors.

  • Open the in-game Settings menu > Go to Options.
  • Click on the General tab > Head over to the Telemetry section.
  • Select Server Latency and turn it on.

15. Reinstall COD Modern Warfare

If none of the methods worked for you, try simply reinstalling the Modern Warfare game from your computer. You can uninstall it via the Battle.net launcher and reinstall it again.

  • Launch the Battle.net (Blizzard) client > Head over to the Game Library.
  • Click on the Call of Duty: Modern Warfare.
  • Click on Uninstall Game from the Options category.
  • Once the game is removed, restart your computer.
  • Now, open the Battle.net client again and download/install the COD Modern Warfare again.

I hope this guide is useful to fix the COD Warzone dev errors 6068, 6065, 6165, and 6066.
