Guild Wars 2

I updated my windows, set the game according to the AMD prefrences GW2 gives, defragged my harddrive, deleted useless programs, and now I have 25 fps avg on high settings so thats a major boost. However i really would prefer a steady 30, if there is any other ways to optimize a PC please let my know, I also heard something about a buggy patch?

I was just wondering if it is normal for my PC to have such bad performance on medium graphics in the beginning section of the game ( right after the cinematic). I get around 15-20fps on the lowest settings and its slightly unbearable, I really do not want to return this game as me and a couple of my mates are playing to play together.

My PC:
Win8 x64
AMD A6-5400K APU 3.6ghz
AMD Radeon HD 7540D
6GB Memory

Sorry if this is an common forum, but I have tried many “fixes” and none have helped so far. Please don’t tell me to just get a new PC/upgrade because my family has low income and a new PC at this time is unreasonable for us.
Any possible fixes/solutions would be much appreciate
Thanks
