well, can't seem to fix it.
but yes, my fps drops, but from 20 to 18 on the slave windows and from 50-39 on the main. I watched task manager and didn't see any other programs putting stress on the cpu/mem. As the fight goes on it gets worse. Fps stays the same but the keystrokes go through slower and slower until they don't register at all. During the first 4-pull in SP I dpsed down the first target and by the time the first fear hit I was unable to control my tank. In the time it took to wipe the rest of my group I was uable to cast a single spell or move my character. A few seconds later a couple of my movement keys went through and he backed up a few feet and turned around.
