Guild Wars 2

i just bought the 660 ti from msi and its runs other games just fine bf3 max 60 fps. but in guild wars 2 when i look forward and run its all fine but the second i turn the fps drops from 45 to about 7 but then when i stop it goes back up to 45 (all done in LA). is this my issue or is this an issue on area nets side of thing as im seeing lots of posts about sudden low frames.

• Try rolling back drivers to 306.23 or 306.97
• Look at Part 4 here for more troubleshooting info

Try disable reflections and turn shadows a little down at the graphics options menu.
