FPS reduces to 1 or 2 while doing invasion or raid

[Botrunner]

Happened to log in on a DK yesterdday but I see this happening on all toons.

Normal FPS on other toons running concurrently is 60, but as soon as I am in an invasion, and then press start on HB, it will drop my FPS to 1View attachment 5056 2016-08-13 23.02.txt

I disabled studio companion mid fight, and as soon as I stop HB it will get my fps back up to 22 or so.
