Fix 2 – Update your graphics driver

An outdated or faulty graphics driver will also trigger Warzone dev error 6328. If you can’t remember the last time you updated your device drivers, definitely do it now as this could make a big difference to your gaming experience.

Fix 3 – Run Warzone on DirectX 11

If Warzone dev error 6328 constantly occurs and the game keeps crashing, you could switch to the DirectX 11 mode, which, as other users reported, gives a smoother gameplay. Here is how to do this:

  1. Run the Blizzard Battle.net client.
  2. Select Call of Duty: MW on the left pane and click Options > Game Settings.
  3. Click the Game Settings tab. Then tick Additional command line arguments and enter -D3D11 in the text field.
  4. Click Done to confirm.

Restart Warzone for the changes to take effect. See if you could get rid of the 6328 error now. If the problem persists, there are a few more fixes to try.

Fix 4 – Increase virtual memory

Virtual memory serves as additional RAM when your computer gets low on memory. Increasing the virtual memory could be a helpful boost when you’re running resource-demanding applications like COD Warzone.

  1. Click the Start button and type advanced system settings in the Windows search bar. Then click View advanced system settings.
  2. Click Settings under the Performance section.
  3. Select the Advanced tab and click Change.
  4. Untick Automatically manage paging file size for all drives.
  5. Select C drive and check Custom size.
  6. Enter the initial size and maximum size depending on the amount of RAM your PC has, and click OK.
    Microsoft recommends you set the virtual memory no less than 1.5 times and no more than 3 times the amount of RAM on your computer. Here is a guide on how to check RAM on your computer.

Fix 5 – Delete the game cache files

The faulty game files can also lead to various issues with Warzone including the 6328 dev error. In this case, you should try cleaning up the cache.

  1. On your keyboard, press the Windows logo key and R at the same time to invoke the Run command. Then type %programdata% and press Enter.
  2. Delete the Battle.net and Blizzard Entertainment folder.

Restart the Battle.net client and see whether you could play Warzone as normal. If the game is still unplayable, try the last method.

Fix 6 – Adjust the in-game graphics settings

If you’re able to get into Warzone and the error 6328 appears only in the middle of the game, tweaking certain graphics settings might help the situation. Here’s how:

  1. Launch CoD Warzone and access the Options menu.
  2. Navigate to the Graphics tab. Then set the Display Mode to Fullscreen Borderless, and turn Sync Every Frame (V-Sync) to On (Enabled).
  3. Scroll down to the Details & Textures section and set Texture Resolution and Texture Filter Anisotropic to Normal.

Save the changes and restart Warzone to test. Then the game should be running perfectly without the 6328 error code.
