Guild Wars 2

So, i have a friend that suffers kind of same, but he goes down to 5fps with a r9 280, he says every other games runs amazing, the only one he has problems is gw2, anyone worked around this?

Finished Verbant Brink, got the engie cache, but it did not count on my collection, should i open it?

So, most of the times in pvp, when i lose a fight i just think “If i have done that…” or “If i had that build…”, but that doesn’t happen when the fight was against a mesmer, even when by a miracle i can get them down, they can sill burst me with their downed skills, this is so frustating.

My main problems are, when i play a condition build, it is very hard to get next them or even shoot them in the range, since their range with Greatswaord is better than ours they just stealth and go enough so they can hit me and i can’t hit them, i may get the point for a longer time, but i am still getting down.

When i go the marauder way with static discharge, most of the time the burst misses or they dodge and then stealth and then i am the one who got burst, they got a lot of time on stealth, so even when i am blocking with the tool kit and dodging, there’s still time to burst me.

Here goes the question: How do you react VS a mesmer? Any tip is welcome.
sorry for my poor english.
