Modern Warfare & Warzone - How to fix dev error 6070

Dev error 6070 in Call of Duty: Modern Warfare and Warzone is another DirectX unrecoverable error. However, despite the DirectX message that displays when launching the game, this problem often tends to appear due to faulty GPU drivers, graphics settings, or in-game overlays.

To fix dev error 6070, you’ll first want to go through a few common troubleshooting steps. These are the things you should try first:

  1. Update your graphics card drivers to the latest version
  2. Check to make sure you’re using a compatible version of DirectX — Modern Warfare and Warzone use the latest version of DirectX 12
  3. Run Windows Update
  4. Disable any software with in-game overlays, such as MSI Afterburner or NZXT Cam

With luck, one of these common solutions will fix the problem. However, there’s one more fix that involves moving or clearing problematic Call of Duty data. Here’s how it works:

First, navigate to the Call of Duty: Modern Warfare folder in your computer’s Documents folder. In there you should find one or two folders labeled player. Rename or delete them, then try launching the game again. If it works, you’ll find that your settings have been reset, including whichever settings that caused the 6070 error. It’s a small price to pay to be able to get back into the game.

Dev error 6070 is one of practically countless Call of Duty error codes without any formal definition. If the fixes above don’t work for you, you should consider reaching out to the Activision Support for an answer.
