So I started playing again, joined my first group content and...

This is happening. My game's FPS drops to 10, stays there, and all the text in my chat log and items disappears. The game is basically unplayable because I can't see anything in chat, my text I type is invisible, and it's extremely laggy. Game was working fine before I zoned into Omen.
I have no idea what's causing this, a quick google says people think it's tied to multiboxing, but I have never multiboxed before and I've never had this problem.
I had it happen a couple times while soloing, but it auto corrected itself... but once I joined a group, it has been permanent. So far it seems to only happen in Omen, but it might crop up elsewhere when I play more?
Any ideas?
