Use DirectX 11 Instead of DirectX 12

Call of Duty games are designed to use DirectX 11 by default. Enabling DirectX 12 can sometimes cause conflicts resulting in fatal errors.

Here’s how to switch to DirectX 11:

  1. Open the or Steam app.
  2. Go to “Call of Duty” and select “Options.”
  3. Choose “Game Settings” then “Additional Command Line Arguments.”
  4. Enter “-d3d11” and confirm the change.

Overriding DirectX 12 usage with -d3d11 forces Call of Duty to run on the more stable DirectX 11 instead. This prevents renderer crashes leading to fatal errors.

Delete the Player Profile Folder

A corrupted player profile folder can also trigger fatal errors in Call of Duty. Deleting this folder resets your settings and clears out any problematic files.

To delete the player folder:

  1. Close Call of Duty and
  2. Open File Explorer and go to Documents.
  3. Find the “Call of Duty Modern Warfare” folder.
  4. Delete the “player” folder inside.

With your player data cleared, launch Call of Duty again to see if the fatal error persists. A fresh profile folder may resolve crashing issues.

Clear the Cache

The cache saves temporary data from games as you play. Over time, this cache can become bloated or corrupted, leading to errors.

Follow these steps to clear the cache:

  1. Exit any open programs using Task Manager.
  2. Press Windows + R and enter “%ProgramData%”.
  3. Delete the entire “” folder.
  4. Relaunch and Call of Duty.

Deleting old cached data forces the app to rebuild its cache fresh. This wipes out any corrupted files that could be interfering with the game.

Lower Your VRAM Usage

Exceeding your graphics card’s VRAM capacity can sometimes trigger crashes in Call of Duty. If you have 8GB of VRAM, try limiting the game to 6GB for stability.

Lower Your VRAM Usage
  1. Navigate to Documents/Call of Duty Modern Warfare/players.
  2. Open the “adv_options.ini” file.
  3. Change “VideoMemoryScale” to 0.75 to restrict VRAM usage.
  4. Save the file and restart Call of Duty.

With your VRAM scaled down, the game won’t exceed the capacity, potentially avoiding fatal errors. You can tweak the percentage higher or lower as needed.

Restart Your Network Devices

Network connectivity issues can also manifest as fatal errors in Call of Duty. Simply restarting your router and modem can clear up problems.
