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’s mentioned below:

1. Run VRAM at Maximum

Here are the steps to find out the VRAM available.

• Click Windows + I > System
• In Display, locate and click on Advanced display settings
• At the bottom of the page, click on Display adapter properties for Display 1
• From the new window, check Total Available Graphics Memory.

This is the most effective method to increase the VRAM. Here are the steps:

• Enter BIOS by pressing the F2, F5, F8, or Del key repeatedly after the restart.
• Go to Advanced/Advanced Options (Note: The exact terminology might vary depending on your hardware manufacturer. Open the manual of the manufacturer for guidance.)
• Now, find Video Settings, VGA Share Memory Size, Graphics Settings, or similar terms.
• 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.

4. Disable Nvidia Overlay

It seems that turning off the Nvidia Overlay application (GeForce Experience) can fix the Dev Error 6066 issue in most cases.

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

5. Update Windows

• Click on Start > Settings > Update & Security.
• Click on Check for updates. If any update is available, simply Download and Install it.
