  1. Install all Windows updates
  2. Update your graphics drivers
  3. Temporarily disable your antivirus
  4. Delete Cache files

Fix 1: Install all Windows updates

Microsoft releases system updates on a regular basis, tackling mainly compatibility and performance issues. Before you continue to anything more complicated, first make sure you’re on the latest Windows 10.

  1. On your keyboard, press the Windows logo key and I at the same time to open Windows Settings. Then click Update & Security.
  2. Click Check for updates. Windows will start searching for available updates. If there are any, Windows will automatically download and install the updates.

After installing all the system updates, restart your PC and check if the error persists.

If this fix doesn’t help you, simply move on to the next one below.

Fix 2: Update your graphics drivers

We always recommend gamers to keep their GPU drivers up to date for the best performance and minimum issues. If you don’t remember when was the last time you updated your graphics driver, you need to check it now.

There’re 2 ways you can update your graphics driver: manually or automatically.

Option 1: Update your graphics driver manually

If you’re a tech-savvy gamer, you can try to update the driver manually. First go to the manufacturer’s website:

Then search your model and find the correct driver installer that fits your operating system.

if you don’t have the time, patience or computer skills to update the driver manually, you can do it automatically with Driver Easy. It will automatically recognize your system and find the correct drivers for your exact graphics card, and your Windows version, and it will download and install them correctly:

  1. Download and install Driver Easy.
  2. Run Driver Easy and click the Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.
  3. Click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system.(This requires the Pro version – you’ll be prompted to upgrade when you click Update All. If you don’t want to pay for the Pro version, you can still download and install all the drivers you need with the free version; you just have to download them one at a time, and manually install them, the normal Windows way.)

After updating your graphics driver, restart your PC for it to take full effect.

Fix 3: Temporarily disable your antivirus

In some cases, it might be your antivirus that’s causing the hassle. To prevent your antivirus from interfering with the game, you can disable it temporarily and see how things go.

Here’s an example of how you can disable Windows Security:

  1. On your keyboard, press the Windows logo key and I at the same time to enter the Windows settings menu. Click Update & Security.
    update & security
  2. Select Windows Security in the left pane, and click Virus & threat protection.
  3. In the pop-up window, click Manage settings.
  4. Toggle off Real-time protection.

Now you can restart Warzone and check if the game loads as expected.

If disabling the antivirus doesn’t help, turn it back on and continue to the next fix.

Fix 4: Delete Cache files

Some users shared that they managed to fix the issue by deleting specific cache files. According to the feedback, this appears to be a less painful solution as it re-downloads a small portion of game content. You can try the same and see if this helps.

Delete these cache files:

File NameFolder Name
Every file ends with .dcacheC:\Program Files\Call of Duty Modern Warfare\main
ppsod.datDocuments\Call of Duty Modern Warfare\players

Once done, you can start Warzone as you normally would. It should download updates and start optimizing shaders.

If this trick doesn’t give you luck, take a look at the next one.

Fix 5: Rebuild your game files

The error could indicate an integrity issue with your game files. You can delete the likely corrupted ones and re-download them using the Scan & Repair feature.

This fix might need you to re-download a large part of game content. A safer option would be reinstalling the whole game. You should choose the measure that suits you the best.
  1. Open your Blizzard Battle.net client. In the left pane, select Call of Duty: MW. Click Options and select Show in Explorer.
  2. Open the Call of Duty Modern Warfare folder. Delete all the files EXCEPT folders.
  3. In your Battle.net client, click Scan and Repair.
  4. Now wait for the process to complete.
If rebuilding these files doesn’t work for you, go back to step 3, delete the main folder and try again.
