Forgive me if some of this sounds pedantic but we gotta make sure you didn't flub the basics. Check the following and see if any of it helps:
  • In-game graphics sliders all to minimum.
  • In-game graphics effects all off.
  • In-game triple-buffering on.
  • wow.exe processes all set to LOW priority
  • wow.exe processes distributed affinity properly (see other threads for specifics)
  • All wow addons disabled as a test to make sure it isn't caused by one addon or too many addons (backup your INTERFACE and WTF folders before doing this so you can reset easily when done testing)
  • In your machine's control panel for ATI or NVidia, make sure your 3d graphics options are set for "performance" and not "quality"
  • Make sure you don't have other processes taking up lots of CPU when you see this problem.
  • No keyclone. If it won't happen w/o keyclone, hmm...
I pretty much have done everything except the tcpackfrequency change which I must be too tired to be able to find ATM for some reason for Windows Vista.

I did make the change to my ATI to have everything set to performance more then quality now. (Most were already at performance except a few)
