Anybody having framerate issues with affliction?

other then the same addons on all my toons, like details, ELVUI and plater, as far as Weak Aura’s, the warlock only has luxthos warlock group.

Demonology Im fine, but if I go affliction half way through a dungeon or half way through a raid boss fight, my frame rate drops to 10-13, when 70 is usually low and 200-250 is normal outdoors.

Trying to locate the issue, I suppose I can start by taking off luxthos’s WA and see, but just curious if anybody has encountered this?
