World of Warcraft on PlayOnLinux: graphics problem
Please install mesa-utils if not yet installed: sudo apt-get install mesa-utils to test for OpenGL support.
Run a check to see if you have OpenGL support: glxinfo|grep 'direct rendering' or /usr/lib/nux/unity_support_test -p.
And run glxgears to see how your video card renders and its FPS for the render.
If it appears you have OpenGL support and all is good then add to the WoW launcher the -opengl parameter. For example '.wine/drive_c/Program Files/World of Warcraft/Wow.exe' -opengl
and test to see the result.
