This has been happening ever since I installed WoW on my Macbook on Thursday, this problem has also remained after a complete reinstall of OSX.
Basically I can load up WoW, login and play no problem at around 20-25 fps but after about a minute, sometimes even shorter the framerate will instantly drop to 3-5fps and stay like it. The framerate drop is instant, from 20 down to 3, I can be standing still or moving and it will do it. I investigated my CPU usage during this and saw the following results.
The red box shows when WoW is running fine with a high average FPS (the minute that it does work properly), the bit in the middle shows when it screws up and runs at a low FPS and the yellow box shows the activity when I close WoW.
I should also mention that if I let the computer go into standby or shut it down then power it on again, I can load up WoW and it'll be fine for another minute or so, re-loading WoW in the same session will cause it to still have low FPS which is visible from the title screen too.
Also I have tried it under bootcamp and it seems to run flawlessly, I don't want to have to use bootcamp though as I know there are plenty of people who can run it under OSX at a proper framerate with no problems like mine. Any idea's I'm new to OSX so I don't know the best way to investigate a problem like this.
