How to Fix “Dev Error 5763” on Call of Duty: Warzone?

The dev errors are the most reported errors on the Call of Duty series games and one such error for Warzone is dev error 5763. The error may occur on the game’s launch or during a match, making the game unplayable. Usually, the following type of message is shown:

Warzone Dev Error 5763

Warzone Dev error 5763 might occur due to many factors but the following can be categorized as the main:

  • Incompatible or Corrupt Graphics Driver: If the system’s updated driver is incompatible with the game or if the driver’s installation is corrupt, then it can cause Warzone to crash with error 5763.
  • Low Value of TdrDelay: The value of the TdrDelay is the time the OS waits before it kills a non-responsive driver and if the GPU is taking a bit longer than the TdrDelay value of the OS, then killing of the GPU driver by the Windows OS may cause the Warzone error 5763.
  • Misconfiguration of Warzone Settings: There are certain Warzone settings (like Cache Spot Shadows, Cache Sun Shadows, or DirectX Raytracing) that may require a high specs system and if the system cannot properly handle load created by these settings, then it may cause the issue at hand.
  • Overclocking of CPU/GPU/RAM or Faulty/Incompatible RAM: Warzone is very picky with overclocking and any type of overclocking can cause the game’s dev error 5763. Moreover, a failing or incompatible RAM may also cause the issue under discussion.

  11. If the issue continues to occur, check if installing an older version of the graphics driver solves the Warzone DirectX error. 

If the issue still persists, check if disabling all the monitors except the primary monitor in the system’s Device Manager (if multi-monitors are being used) solves the problem. Check if changing the PCI-E Y splitter cable of GPU to 2 cables solves the problem.

Edit the System’s Registry to Increase its TdrDelay 

Timeout Detection and Recovery delay (TdrDelay) is a Windows technique in which the Windows OS waits a certain amount of time before killing a driver due to a non-timely response. If the TdrDelay is less than what the GPU may take to render a request, then the OS may kill the graphics driver in the operation and thus cause the Warzone to crash with dev error 5763. In such a case, increasing the TdrDelay of the system by editing the system’s registry may solve the problem.

Warning: Advance with extreme caution and at your own risk as editing the PC’s registry is a skillful task and if anything goes wrong, you may cause everlasting damage to your data and system.  

  1. Click Windows, search for RegEdit, right-click on its result, and in the sub-menu, select Run as Administrator.
    Open Registry Editor as Administrator
  2. Then navigate to the following path:
    Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers
  3. Now, in the right-pane, check if the TdrDelay value is present (if so, follow steps 6 and onward).
  4. If not, then in the left pane, right-click on the GraphicsDrivers registry key and select New>> Dword (32-bit) Value.
    Create a New Dword (32-bit) Value Under GraphicsDrivers Registry Key
  5. Now, name the value as TdrDelay and double click on it.
  6. Then change the Base to Decimal and set its value to 60.
    Set TdrDelay to 60
  7. Again, create another Dword (32-bit) Value and name it as TdrDdiDelay.
  8. Now double click on it and change the Base to Decimal.
  9. Then set its value to 60 and close the Registry Editor.
    Set TdrDdiDelay to 60
  10. Now restart your system and upon restart, launch Warzone to check if it is clear of the dev error 5763.

Uninstall MSI Afterburner

MSI Afterburner is one of the top utilities to monitor and overclock a graphic card. If the monitoring or overclocking capabilities of this application is interfering with the Warzone’s game modules, then it may result in the dev error 5763. In such a case, uninstalling the MSI Afterburner may solve the problem.

  1. Right-click Windows and select Apps & Features.
  2. Now expand Afterburner and click on Uninstall.
    Uninstall MSI Afterburner
  3. Then follow the prompts on the screen to complete the uninstallation of Afterburner and once done, restart your system.
  4. Upon restart, launch Warzone and check if it is working fine.
  5. If not, check if performing a clean boot of the Windows PC solves the problem. If so, you may find out the problematic startup application by enabling them one by one till the culprit one is found. 

Disable XMP Profile in the System BIOS

Many gaming PCs come with a factory-enabled XMP (Extreme Memory Profile) profile and the overclocking by XMP is a reported culprit to cause the Warzone game to crash with dev error 5763. If your PC has this overclocking XMP profile or similar features like DOCP or EOCP, then that can cause the issue at hand. Here, disabling the XMP profile in the system’s BIOS may solve the problem.

Warning:

Proceed with extreme caution and at your own risk as editing the system’s BIOS is a proficient task and if it does not go well, then you may brick your system while causing undying damage to your data.

    Disable XMP in BIOS
  3. Then select Disabled in the dialogue box and exit BIOS after saving the changes made.
  4. Now boot your system into Windows and launch Warzone to check if error 5763 is cleared.

Reset the System’s BIOS to the Factory Defaults

Warzone’s crashing with dev error 5763 could be a result of a mere misconfiguration of the system’s BIOS. In this context, resetting the PC’s BIOS to the factory defaults may clear the Warzone’s error 5763.

Warning:

Advance at your own risk as editing the PC’s BIOS is a skillful task and if it goes wrong, you may brick your PC and cause everlasting damage to your data.

  1. Boot your system into the BIOS and near the right bottom of the screen, click on Restore Settings.
    Reset BIOS to Defaults
  2. Then confirm to restore the BIOS settings and once completed, boot the system into Windows.
  3. Now launch the Battle.net launcher and open Warzone to check if it is operating fine without the dev error 5763.

If that did not work, check if disabling the Energy saving features in the BIOS (like C-states, SATA APM, etc.) and in the Windows Device Manager (especially, for LAN and USB ) solves the problem.

  6. Once done, launch Warzone and check if it is operating fine without showing the dev error 5763.

If the issue persists, make sure the system’s NAT type is open, proper ports with the exact system IP are forwarded in the router settings, and then check if the game’s DirectX problem is solved. 

Reinstall the Warzone Game

Warzone may start showing the dev error 5763 if Warzone’s installation is corrupt. In this case, reinstalling (100GB+ download size) the Warzone game may solve the problem. Before proceeding, make sure to back up the essential info/data of the Warzone game.

  1. Launch the Battle.net client and in the games, select Warzone.
  2. Then, open its Options menu and click on Uninstall.
    Uninstall Call of Duty Warzone
  3. Now confirm to uninstall the Warzone game and once the uninstallation is complete, restart your system.
  4. Upon restart, right-click Windows and open Apps & Features.
  5. Now expand Warzone (if shown in the installed apps) and click on Uninstall.
  6. Then confirm to uninstall the COD game and follow the prompts on the screen to complete the game’s uninstallation.
  7. Once completed, restart your system, and upon restart, delete the leftovers of the Warzone game in the following directories:
    %temp%
    
    C:\Windows\Temp
    
    C:\Program Files (x86)\
    
    C:\Program Files\
    
    C:\Program Files\Common Files\Blizzard Entertainment
    
    C:\Users\Public\Games\
    
    C:\Users\Public\Public Documents\Blizzard Entertainment\
  8. Once done, restart your system and upon restart, reinstall the COD Warzone game.
  9. Once installed, launch Warzone, and hopefully, Warzone will be cleared of the dev error 5763.

Revert the Overclock Settings of System to Stock Speeds

Warzone is reported to not go well with any type of overclocking speeds (either factory overclocked or by the user). As overclocking is a vast topic, we can just say, make sure the overclock settings (CPU, GPU, RAM, etc.) are set to stock speeds (in some cases, underclocking) and then check if the Warzone issue is resolved. Some users reported that removing the base overclock on the GPU worked for them, so, make sure that is not the case with you.

Check The System’s RAMs

If none of the above solved the dev error 5763, then most probably a faulty or incompatible RAM is causing the issue. Firstly, check if increasing the RAM voltage (e.g., from 1.35v to 1.39v) solves the problem. If that did not work, you may remove the RAM sticks one by one and launch the Warzone game till the problematic one is found. You can also use Windows Memory Diagnostic or Memtest to find out a failing RAM. If you have some spare RAM available (or can have from a friend or family), then check if using those RAMs solves the Warzone problem.
