Noob question
Seems about right unfortunately. GW2 benefits most from a high clocked CPU, which laptops just don’t have.
Ye, you have an i7 but one with a very low clocked CPU. This is propably your bottleneck. Besides Internet speed does not affect FPS as far as i know. Its Ping that is affected by your internetquality.
For those switchable amd gpus there are quite useful custom drivers on the internet Id try them first to see if it helps a little bit. Game is still like under construction not even close to being optimized so before getting paranoid you should give it some time.
Also do you play any other sort of Mmo/fps anything online? How do they perform on your device? Tried lowering in-game detail settings to see if it makes any difference cuz 1080p GW2 is quite heavy for the 6770.
Gonna be waiting a very, very long time if you expect them to improve performance more than 10-20%. Just look at SWTOR or Rift.
