I have been experiencing an issue since the patch.

My main window will jump to 100% CPU across all cores and FPS will drop to 5fps while the other windows operate normllly.

To get the cpu back under control, i have to kill the client or bring up task manager and preform an administrative task on the client which causes the user control window to pop open. Once Task Manager opens back up the cpu goes back to around 70%. I have disabled everything in the UI but Xperl and my action bars. Graphic settings are down.
