Guild Wars 2

Im having a slight issue with two different computers. Im running both at max settings. One has a quad core and the other a i7. Both have sufficient ram and run the game smoothly but Im noticing that as Im running to an area, such as the lions arch bank, I dont notice characters until Im right up on them. This isnt so bad in PVE but when heading out into wvwvw Ill probably run up on a group of enemies before I even know they are there. Updated all graphics drivers. Im just wondering if its still optimization of the servers or some kind of lag that is causing this issue. Any recommendations would be greatly appreciated.

Ive read a few forums with similar issues but none with answers to these issues.

This has less to do with your hardware, and more to do with the game client and server. When there is a particularly high concentration of avatars (NPCs or player characters), it will take awhile for the game to register each one and load the appropriate sprites.
