I don't know if it's actually a lag problem, but my mouse seems less responsive when using it on my qck steelseries mousepad. The problem is that whenever I go to the top right of my mousepad or down to the lower left corner of my mousepad, my cursor lags and doesn't go as far as to when i go to the top left corner of my mousepad or the lower right corner of my mousepad. Now i've tried my mouse directly on the tables surface and I've got no lag whatever. Then i tried my brotherss mousepad and it lagged again (both of our mousepads are cloth mousepads). This problem only started a couple of days ago. Apologies if my English is bad. Hope you guys can help me and my crappy description of my problem ^^
