Guild Wars 2

Seems quite random, and it started happening after the last update I think. Does anyone else have this bug? What’s your hardware configuration? ASUS N55 laptop here, i7-2670QM + GeForce GT555M + latest NVIDIA beta drivers (though the same happens with release 306). The mouse is a Razer Orochi (though that shouldn’t really matter).

Monitor your CPU and GPU usage when you move your mouse. Maybe something is running in the background or something related to the mouse. (Read Q5 for tools to monitor)

I tried monitoring with NVInspector and Process Explorer, and there’s nothing eating CPU power too much. However, I think I found the culprit. Turns out, 1) you’re never right with basic assumptions on Windows, and 2) it’s the mouse. It works fine with my touchpad, but moving the Razer mouse causes lag to appear. Messing with the drivers, firmwares and stuff now, no luck yet.

Another update: happens with any external mouse, doesn’t happen with the touchpad even when both external mice are connected.

And another update: in windowed mode, lag is only present when moving the mouse inside the game window. By now I’m pretty sure it’s a bug.

does it matter if you are using wired or wireless mode?

No, anything USB breaks it. Just tried with an ancient Genius dumbest-mouse-ever. Also did a repair install and reinstalled drivers for all the mice. No go. Reported a bug to ANet Support.

Solved. Tried to think of what was using the mouse, found Dexpot. Closed Dexpot, now it all works. Now to go bug Dexpot developers.

I am using dexpot 1.6.3 build 2167 without any issues, I haven’t tired the newer 1.6.4 yet.

I think it broke in 1.6.4. Maybe it’s just my setup though. Do you have screen corner mouse gestures enabled?

I only use dexpot for the window catalog expose clone feature & multi desktop. Everything else was left at default settings.
