Lag Meter
You can see your FPS by hitting ESC and going to game settings. It shows your FPS in the bottom right of the window.
While there isn’t any in-game latency indicator, you can find out your current ping to the game servers by using the tools integrated in your Windows OS, provided you’re running Windows 7. When in-game, hit Ctrl-Shift-Escape to bring up the Task Manager, then go to the Performance tab and hit the Resource Monitor button at the bottom. In the newly opened window, go to the Network tab, tick the checkbox next to the Gw2.exe process and in the TCP Connections subview, you should see list of all connections opened by Guild Wars 2. The last column of that view is called “Latency”, and you’re interested in the connection that was opened on port 6112.
Hope that helps!
This is almost essential for WvWvW and sPvP. I’ve had a number of times when my abilities were delayed by over five seconds and rubber banding kicked in hard. I need to know when there’s something up as soon as possible.
