However, some users may encounter an unsupported device warning while attempting to run these games on certain devices. This warning can be frustrating, as it prevents gamers from enjoying the game. 

Let’s explore the causes behind the unsupported device warning and provide solutions to fix the COD issue.


Understanding the Unsupported Device Warning Message on Call of Duty MW2 and Warzone2

When players receive an unsupported device warning, it typically means that their computer’s hardware or software does not meet the minimum requirements to run the game smoothly.

Causes of this COD Device Compatibility Issue

Outdated Graphics Drivers

One common cause of the unsupported device warning is outdated graphics drivers. Graphics drivers act as a communication bridge between the operating system and the graphics card. If the drivers are outdated, the game may not recognize the graphics card properly, triggering the warning.

Incompatible Hardware

Another cause of the unsupported device warning is incompatible hardware. Specific components, such as older graphics cards or processors, may not meet the game’s minimum requirements. In such cases, the game will generate a warning to prevent potential performance issues.

To address the issue of outdated graphics drivers, visit the manufacturer’s website for your graphics card and download the latest drivers. Install the drivers on your system and restart your computer. This step ensures that your graphics card is recognized correctly by the game.

Check the box that says “Run this program in compatibility mode for,” and select a previous version of Windows from the dropdown menu.
