Thanks, for the facts,

Well, I play on Chrome because I have tried other browsers and I get a severe fps drop. I have tried Firefox, IE, and Opera.

So, right to it I'm using shaft and when i move my turret while in sniper mode it goes in a grid like pattern such as up and right then down. I cannot move my turret when sniping in a smooth pattern, I cannot use shaft now because it takes too long to aim at a tank and shoot, unless if it is a titan or mammoth m0 -m1. I believe that my problem is keyboard ghosting, and I have done all the steps that was recommended to me and i still face this problem. If there is such thing as another solution please, I would appreciate them.
