WoW will not launch with DX12 enabled

Support Technical Support
1

In anticipation of the Tides of Vengeance performance changes, I recently made the switch from Windows 8.1 to 10 and did a clean reinstall. Since then, I’ve been unable to launch the game with DX12 enabled. If the DX12 setting is enabled in the in-game options, the only way I can launch the game is by running the .exe in Windows 8 compatibility mode so that it forces the game to switch to DX11.

The error log shows the following:

I have tried the following solutions:

  • reinstalling WoW and running it without addons
  • increasing virtual memory
  • disabling the XBox app Game DVR
  • updating NVidia drivers
