In your screenshot you have vsync set to On, but in the text description of Vsync it says to have it set to Off if you want to use free sync:

If this isn’t the issue can you describe more why free sync isn’t working on dx12 (but is on dx11). Or are you meaning you just get less fps on dx12 ?

  • [Display and Graphics]
    • Improved: Performance has been improved when apps query monitors for their full list of supported modes. When this happens it could previously lead to a momentary stutter on very high-resolution monitors. This work should help prevent and reduce stuttering in these scenarios.
    • Fixed: All-in-one PCs might experience issues with their brightness slider, where it unexpectedly reverts to the original brightness when interacting with it.
    • Fixed: Recently certain games might display the message Unsupported graphics card detected, although a supported graphics card is used.

finally it’s working
