1. Check the System Requirements

The Call of Duty: Warzone is only supported by Windows 10/11. If you want to play the game seamlessly, make sure the system meets the game's minimum requirements.

The minimum system features required to play the Warzone are:

A windows computer with a 64-bit operating system, 8 GB RAM, 175 GB of hard drive storage space, and a high-performance graphic card like the Nvidia GeForce GTX 670 or 1650 or AMD's Ryzen HD 7950 or more.

Any PC with moderate features is well-suited for playing the game without any issues at this point. We can check the requirements in the DirectX diagnostic tool, a Windows feature providing backend support to the games on PC.

Steps to check the system specifications of your PC:

Step 1. Press the Windows + R keys at a time to open the Run App.

Step 2. Enter the "dxdiag" and run the command to see the system specifications.

If your system does not meet the game's minimum requirements, that could be the reason for the dev error. Make sure to add or replace the hardware to support the game.

2. Update the Windows OS

Sometimes, if the OS lacks some necessary packages or software components, it could cause the dev error 6634 while playing the game. In such cases, check for the OS update on your PC and update the software.
