Just bought new pre-built. All other apps ok, but when I downloaded gw2, problem started. When the screen where you log in opens, mouse cursor starts to lag bad. The lights on keyboard start to go on and off constantly as well. In game, no issues. Also, another real weird thing. I tried to use steam to open. Steam was fine, but once I added gw2 to library, same cursor lag and keyboard light issues. Anyone know of a solution?
