Having lag issues here too. It's not really a big issue most of the time, but on boss fights it's a pain to avoid attacks. I just fought Titan and had to keep moving non/stop to avoid the attacks. As a healer this proved a bit difficult. I doubt I could do it in hard mode.

Zebnatsan, could you share the name of the application you are using on those screenshots. I normally use the resource monitor for this, but that one looks nice.
