I'm trying to launch the WoW.exe for the Cataclysmic Expansion. I keep getting this Error message stating " World of Warcraft was unable to start up 3D acceleration. Please make sure DirectX 9.0c is installed and your video drivers are up-to-date. "
All my drivers are up to date and I have DirectX 12. I re-downloaded the game twice already in-case it was a download error. I hope someone can help me and Thanks!
I checked my config.wtf and saw a line missing. So I added SET gxApi "OpenGL" and I can finally launch the game.
Update: "OpenGL" fixed it, but wouldn't let me run the game with ULTRA settings. I changed it to Set gxApi "D3D11" and it finally fixed all my problems.
Note: I'm posting this in-case someone runs to the same problems..
