Technical support thread would have been a better place to post since some people ..myself included ..like to lend there knowledge to help ppl. Luckily i also check this part of the forum
Anyway…
laptops & gaming do not mix well unless you spend alot on them. With that said certain games would run well on your laptop. WoW being one of them becouse it uses a very old game engine that can be easily run on almost any modern CPU and GPU.
GW2 however uses a more modern game engine. Granted its the same GW1 engine ..but it is highly modified. This engine takes ALOT of performance from the CPU and as such you need a pritty beafy cpu to run it in all its glory.
All laptop CPU currently available will fall short of being able to handle GW2’s most intensive areas such as large WvW fights without droping below 30 fps.
Even top end Intel Desktop CPU’s need OC’ing to be able to stay above 30fps in WvW, and on AMD’s side the FX 8350 is able to produce simular results.
GPU wise you need atleast a top end dedicated desktop media card like a Nvida 550ti or a AMD 7770. For a laptop that wold be equivalent to maybe a GTX 570m or AMD 6900m.
I understand as a student you dont have the money for a high performance gaming laptop that could atleast play PVE.. and also dont have the ability to use a Desktop since your likely living away form home. Im afraid there isnt much you can do.
The only advice i can give you is to shutdown ever single possible process you have running the background to free up as much ram and processor usuage as you can. however if your GPU is whats slowing you down which it does look like ..there isnt anything else you can do.
EDIT: if your living at home then i see no reason why you shouldnt have a desktop computer, even is space is at a premium there is ways of making a computer not that much bigger than a small wine/beer cooler ..plus a monitor keyboard and mouse ofcourse, that could handle GW and i beleve (som1 from the US correct if im wrong here) that with current sales on $550 would net you a ncie rig.
