Problems with nexus king salhadaar

Hi, as i wrote up im having a problem with this boss of omega mana forge.

The problem is principally that when i start the boss the game just instant crash and is a mess. After reinstall graphic drivers it started to go well but after 10 mn it crashed again and its happening only in this boss in heroic and is pissing me off because this dont happend in normal or in other bosses. Any idea?

Ask on the WoW forums instead of here ?

I’m also having This problem, never had trouble running the game at high graphics for years, this one boss crashes my computer every pull even when I lower all my settings as low as possible. Would love some kind of suction cause Iv tried everything I can think of
