Before diving into the fixes below, please make sure your gaming rig satisfies the Warzone minimum system requirements.

Fix 1 – Install the latest game patch

New games usually come with a lot of bugs or issues, but thankfully developers will release new patches to fix them. So, when Warzone constantly crashes on your PC, the very first thing is to check for the available update and install it.

If this doesn’t work, you can dig into other possible causes such as the graphics driver, running programs, game files or virtual memory setting.

Fix 2 – Update the graphics driver

A range of gaming problems like crashing and freezing is caused by a wrong, faulty or outdated graphics driver. Call of Duty Warzone is no exception. To enjoy a smooth gameplay, you should always keep your graphics driver up to date.

You can search for the latest graphics driver from your graphics card’s manufacturer such as AMD or NVIDIA, and then manually install it. But if you don’t have the time, patience or skills to update the driver manually, you can do it automatically with Driver Easy.

Driver Easy will automatically recognize your system and find the correct drivers for it. You don’t need to know exactly what system your computer is running, you don’t need to be troubled by the wrong driver you would be downloading, and you don’t need to worry about making a mistake when installing.

You can update your drivers automatically with either the FREE or the Pro version of Driver Easy. But with the Pro version it takes just 2 steps:

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 the Update button next to the flagged graphics card driver to automatically download the correct version of that driver, then you can manually install it (you can do this with the FREE version).

Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system.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 which comes with full support and a 30-day money back guarantee. You’ll be prompted to upgrade when you click Update All.)

You can do it for free if you like, but it’s partly manual.
The Pro version of Driver Easy comes with full technical

Now test if the new graphics driver renders Warzone in a stable and enhanced performance. If the crashes still don’t stop, there’re more fixes to try.

Fix 3 – Verify the integrity of your game files

Missing or damaged game file is another known culprit of Warzone crashing on PC. But don’t worry, resolving this problem is as simple as making a few clicks.

1) Run your Blizzard client.

2) Click Call of Duty: MW in the left pane. Then, click Options and select Scan and Repair from the drop-down menu.

3) Click Begin Scan.

Relaunch the game after the process finishes, and see if everything goes back to normal. If Warzone keeps crashing, head to the next fix below.

Fix 4 – Close unnecessary background applications

Your background applications can conflict with CoD Warzone or drain much system resource and thus trigger the crashing issue. To shut down all unnecessary applications, you could follow the steps below:

1) Right-click on any empty place in the taskbar and click Task Manager.

2) Right-click the application you want to close and click End task.

Don’t end any programs you’re unfamiliar with, as they may be critical for the functioning of your computer.

According to some players, killing Kite.exe and related processes specifically resolves the issues, so you could give it a try.

After closing everything else in the background, you should find CoD Warzone runs normally. If the crash is still there, check out Fix 5.

Fix 5 – Adjust the graphics settings

Many players reported that texture streaming, a new feature added in the recent CoD Warzone update, will cause Warzone to crash.

Therefore it’s recommended you disable Texture Streaming as well as V-Sync and also lower other graphics options to improve the game’s smoothness. If this doesn’t help, continue to more fixes below.

Fix 6 – Switch to DirectX 11

For players who encounter the crashes with a specific DirectX error, switching to DirectX 11 may enable the game to run stably. Here’s how:

1) Launch the Blizzard client.

2) Select Call of Duty: MW from the left pane and click Options > Game Settings.

3) Select Game Settings. Then, tick Additional command line arguments and enter -D3D11 in the text field.

4) Click Done to apply the changes.

Restart your game to see how thing goes. If the problem persists, go ahead with the next fix.

Fix 7 – Increase virtual memory

When your computer gets low on memory, virtual memory serves as additional RAM. But if it’s not sufficient to handle some resource-demanding applications you’re running, such as CoD Warzone, the crashing issue will occur. To see if that’s the case, try extending the virtual memory as follows.

1) Click the Start button and type advanced system settings in the search bar. Then, click View advanced system settings.

2) Click Settings under the Performance section.

3) Select the Advanced tab. Then, click Change.

4) Uncheck Automatically manage paging file size for all drives.

5) Select the C drive and click the box next to Custom size.

6) Enter the initial size and maximum size depending on the amount of RAM your PC has. Then, click OK.

According to Microsoft, the virtual memory should be 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.

After you complete the steps above, test if Warzone works well. If the same crashing issue comes back, proceed to the next fix below.

Fix 8 – Temporarily disable Windows Defender

Windows Defender aims to protect your computer from threats or hazards, but it may block some of your applications by mistake and stop them from operating properly. So you can temporarily disable the Windows Defender and see how Warzone works.

If you’re on Windows 10

If you’re on Windows 7

Windows 10

1) On your keyboard, press the Windows logo key and I at the same time to enter the Windows settings menu.

2) Click Update & Security.

3) Select Windows Security in the left pane, and click Virus & threat protection.

4) In the pop-up window, click Manage settings.

5) Toggle off Real-time protection.

Restart your computer and launch Warzone to test this method. If Windows Defender isn’t the reason to blame, move on to Fix 9 then.

Windows 7

1) On your keyboard, press the Windows logo key and R at the same time to invoke the Run box. Then, type control in the field and click OK.

2) Select Small icons under View by, and click Windows Defender.

3) Click Tools. Then, click Options.

4) Select Administrator in the left pane, and untick the box next to Use this program.

5) Click Save.

Restart your computer and launch Warzone to test. If you still run into crashes after applying this workaround, try the next fix below.

Fix 9 – Disable overlay

The overlay feature provided by third-party programs can be the reason for CoD Warzone crashing. So, you should turn it off during the gameplay. Below we’ll specifically show you how to do this on Discord and GeForce Experience. If you’re not using overlay at all, please jump to Fix 10.

On Discord

1) Run Discord.

2) Click the cogwheel icon at the bottom of the left pane.

3) Select the Overlay tab in the left pane and toggle off Enable in-game overlay.

On GeForce Experience

1) Run GeForce Experience.

2) Click the cogwheel icon at the upper right corner.

3) Toggle off In-game overlay.

If disabling the overlay fails to fix your problem, please try the last method.

Fix 10 – Rename the game file

If all else above doesn’t help, try renaming the game file. This method sounds a bit weird, but it works like a charm for many players stuck in the endless crashes.

1) Launch the client.

2) Click Call of Duty: MW in the left pane. Then, click Options and click Show In Explorer.

3) Open the Call of Duty Modern Warfare folder.

4) Double-click the ModernWarfare.exe file and rename it as ModernWarfare.exe1.

Open Warzone and see whether you can enjoy it without interruptions now.
