dk lag

Hi guys i have problem about two weeks ago maybe more i spotted something that bothers me,when im using spells on my frost dk my screen keep lagging until i stop using skills it just happens on dk everything else is fine,can i solve this somehow?

Perhaps it's an issue with too many animations going on at once, although I doubt it. Try turning down your graphics to the lowest setting and then running the same progression of spells again.

well i tried that too but it doesnt help

what addons do you have, it may be the cause

some other guy told me that too and he told me to turn off all oddons but i dont have addons in options ..

Are you using the client with LoD models? I noticed that it's way heavier and I lag much more using it instead of the old one

What expansion is this?
I believe it could be spell effects thats causing this, Frost DKs spells are pretty detailed and heavy on potato computers.

Well i have 8 gb ram 3.40 ghz processor 7770 1 gb and i dont think its potato hahah,but i dont know its just when im using spells
