Guild Wars 2

Hi,

Today my fps is just horrible, nearly unplayable. I used to play with around 30 fps at max details, not mentionning that ppl with lower pc specs than mine are having better results.
Today with max detail, I get like less than 5 fps?? And even with the lowest configuration, I get a max of 40 fps, that is absolutely not normal. Is that because of the new update or so? Below are my hardware specs. I really hope you can help, because this ruined my day.

Intel I7-3610QM
nvidia GTX 670M – 3GB GDDR5 (latest driver 306.02)
DDR3 8GB
SSD

Thank you.
