Guild Wars 2

i have tried and set the graphics setting in both hi-performance and (best visual), and my fps only get a 3-7 fps hit when i go for the default best visual settings of the game.i wanna improve my fps cause in spvp or events i have some problems…
so here is my question :
which setting i should custom fix to win some fps?
i have ati so if you have any suggestions settings for the catalyst settings feel free to give me your advice cause i am not an expert.

Really need to know what your PC specs are >.<

ok here they are :
i have a core2 duo e6750 2.66 Ghz
2GB ram
ati radeon 4890hd

my cpu and ram are not that good but still seems crazy to me that i have 25-30 on the best performance settings and 20-25 when i play on the (best visual ) setting

I don’t think messing with the GPU will do much, your CPU+RAM are holding you back.

So is your RAM. When I have GW2 open, I see 4Gb of RAM being used – granted, I don’t close out of all background programs, but 2Gb is just not enough. Are you running a 34-bit version of Windows ?

Upgrading RAM would be my first step. While you won’t get benefit over 4Gb (and less in reality) with an x34 system, even that should help.
