Howdy!
We are investigating a possible driver issue with AMD GPUS that impacts the game’s ability to launch with DirectX 12.
The first step I recommend is to clear the shader cache following the steps Here.
Then launch the game with directX11 API:
- With the Battle.net desktop app opened and WoW selected click on Options
- Select Game Settings
- Find WoW and check the box for Additional command line arguments
- In the new box enter the command for the desired DirectX version:
-d3d11
- Click Done to save.
NOTE: With DirectX 11 FPS may not be as high as expected, you can lower graphics quality settings to counter this until the issue has been resolved.
Thank you.
