Today I suddenly noticed huge frame drops when going into combat on my DK.

I turned off all my addons one by one and found out it's Autobar. I tried swapping around settings turning off certain bars, but the pikes and massive frame drops continue.

If I turn off Masque, the stutters are a lot less apparent and quicker. WIth only Autobar turned on, I have no stutters. It must be autobar + something else.

Second update. Been playing with settings for hours..

I don't think it's autobar directly. I had to go through all my graphic settings and swap them around to get the stuttering to stop with autobar enabled. Not sure why. But my GPU is only at 20% usage while my frame rate was stuck about 10-20 frames lower than my settings.

Something in the last Nvidia Driver update + WoW patches must have bugged out my config file.
