yes, this is one of the pitfalls of GW2, it seems to have unusually high demands of hardware despite the fact that it doesn't appear to be a terribly graphically demanding game (IE, the graphics are not the best)

I would imagine the GW2 will be free from here on out so you can take your time. After grinding to level 40 in FF14 and trying to do some crafting only to not be able to figure it out without the help of a wiki, i may be done with it soon.
