World War Z: Aftermath Crashes

General Tips

Please try these steps if your game crashes:

  • Verify game files (Epic Games Store or Steam).
  • If you're playing on Vulkan, try going into Settings > Video and switching to DirectX11.
  • Disable built-in\integrated GPU.
  • Update your drivers to the latest version.
  • Apply the latest Windows updates.
  • Try running the game as an Administrator.
  • Try using AMD Clean Up Utility.
  • Disable Image Sharpening in NVIDIA GeForce Experience.
  • Disable Fullscreen Optimizations.
  • Try setting a higher priority for World War Z in Windows Task Manager.
  • Delete the video.dat file located C:\username\AppData\Local\Saber\WWZ\client\storage\video.dat and try to launch the game.
  • Try disabling all controllers (steering wheels, gamepads, headphones, and even a keyboard) before starting the game. In some cases, they can cause unexpected issues.
  • Close all applications that may use the microphone and audio or boost performance (Discord, Skype, MSI Afterburner, and others) in the Task Manager before starting the game.
  • If you have multiple monitors connected, try leaving only one primary.

We recommend doing a full clean of GPU drivers and making a fresh install of the latest version. If a new version doesn’t fix it, try one of the older ones. NVIDIA recommends Display Driver Uninstaller for clean removal, so you may want to start with it.


Steam Client Configuration

Try clearing Steam's Download Cache files:

  • Open Steam, then navigate to the Settings tab located at the top-right corner of the page.
  • Click on the Downloads option.
  • Click Clear Download Cache and click Confirm to proceed with the action.

You can try changing Steam configurations to improve your in-game experience:

  • In Steam, click on the “Library” option (you’ll get a complete list of the games you play). 
  • Right-click on World War Z.
  • At the bottom, there’ll be an option named “Properties”.
  • Click on the “Set Launch Options” button.
  • In the dialogue box, write -autoconfig and press the OK button.

If this issue is present, try to launch the game with the Safe Launch option:

  • Repeat the same procedure as mentioned above.
  • In the dialogue box, write -safe and press the OK button.


Epic Games Launcher Cache

You can also try to clear the Epic Games Launcher's cache:

  1. Exit the Epic Games Launcher by right-clicking on the system tray icon in the bottom-right corner and then clicking Exit.
  2. Press the Windows key + R and type “%localappdata%” to open a File Explorer window.
  3. Open the Epic Games Launcher folder.
  4. Open the Saved folder.
  5. Click the “webcache” folder, and then delete it.
  6. Restart your computer and start the Epic Games Launcher.

If the game keeps crashing, there should be a CrashDump file in the following folder: C:\users\*username*\AppData\Local\Saber\CrashDump.dmp


Console General Tips 

  • Check the game for updates, and install them, if any.
  • Reinstall the game.
  • Clear your console’s cache files (see the respective guide from your platform).

Back up your saved data and reset the console. Please note that resetting your console erases all data saved on your console storage.
