Guild Wars 2

I have notice on buying guild wars 2 and installing it that lion’s arch has the most fps drop out of all the major cities and its so massive. Is it possible to have a setting in the graphics to add portals in lion’s arch to make lions arch separate from the massive environment surrounding lion’s arch core structure.

On a side note.
-All other cities and environments don’t seem to drop as much in fps.

The game client lost its connection to the server. Please wait a few minutes before restarting the client and trying again.

I am guessing this is not my fault because my connection is perfect. Like to know what you guys think.

I have notice in some parts of GW2 that my pc can’t handle which are Lion’s Arch, Big massive battles and waypoint spawning. I have notice that when i spawn into lion’s arch that i get 50fps then when i move from my spot it goes to 40 the 30 back and forth.
My setting for my PC are here:
I5-2500 quad core@ 3.30 GHZ
8gbs of ddr3 kingston hyperx 1600
evga gtx 560 ti
1 tb western digital 7200rpm hard drive
Asus P8Z 68-V LX motherboard
