Well lets start with the bad news, i dont play WoW anymore.
Thus i havent updated the guide.
The terrible news are, i once accomplished to get 25 fps, following my own guide, but never ever again since.
That was the time i had noted down every setting, just to figure out, none of those settings brought the same result after a fresh reinstalltion of Fedora 15, wine and WoW.
The good news are, IF you install wow from scratch, and you pass the launcher installer by 10% or more without issues, you have very good chances that wow will run smoothly.
Have you tried the script i had provided in that thread?
Since i havent touched them again, they still should work well on F15.
Havent tried with F16, and wont do anywhere in close future.
Having an Intel 'GPU' myself, my experience is that it differs very much of a mixture between openGL and directX.
Lazy saying: Optimze for openGL while having directX installed.
But the results differ as they seem to be diffrent with every diffrent chipset.
Havent changed my hardware since i wrote that guide, but the FPS (and the settings that the fps even matters) seemed to be diffrent with every update, as the FPS varied from between 0.1-0.3 over 5-8 to 15-35.
So, since like 100 updates had passed, i have no idea what settings could even matter anymore.
But to give you hope, play with all available settings (winecfg, winetricks), note them down and check your fps.
You will find out that one setting doesnt make a diffrence at all, while the same change varies alot if something.
