I have been plagued by DirectX, I have to stick to use OpenGL to workaround those shitty graphic problem. Low FPS is 1 of them.

Try a search in WoW tech forum, try the keyword OpenGL.
What it do is set your WoW config to run graphic using OpenGL instead of the default DirectX.

My problems with DirectX:
- Missing ground or wall textures, some time ago. Now not -yet- hitting them.
- Screen went blank. have to reboot
- Game freeze\hang. have to reboot
- suddenly SLOW, LOW FPS.

Everytime WoW released a new patch, or I updated latest driver from Nvidia, I will try the game using default mode DirectX. But it never stay good and stable for 1 whole game after starting some patches ago.

I have to use OpenGL. The only thing with this not so good, is when alt-tab out, its slow. But its STABLE.
