In Act 2 stutters, freezes and disconnects

I first noticed when I used an orb to augment something. The screen starts stuttering and the sound of the upgrade goes into an infinite loop. I logged out, closed the game and went back in and started playing in Deshar. As I was playing the stuttering happened during a mob fight, and the sound loop happened. Then it froze up, said game is paused and logged me off the server.

The game is unplayable right now because any activity leads to this same issue.
