DirectX 12 is Not Supported on Your System: 4 Ways to Fix it

Many users reported DirectX 12 is not supported on your system, try running without the or command line argument message, and this will prevent you from running certain games. However, there might be ways to fix this issue.

How can I fix DirectX 12 is not supported on your system error?

1. Check if your PC supports DirectX 12

1. Press Windows key + R and type dxdiag.
   
2. Navigate to the Display tab.
3. In the Drivers section look for Feature Levels. If it says 12_1, 12_0 it means that DirectX is supported.
   

Keep in mind that some games require Feature Level 12_2, and if your graphics card doesn’t support it, you won’t be able to run it.
