Got it a fairly long time ago as a RAT 7 died on me within a day so i gave up on that brand. I got it and installed the drivers and have since removed the software, as it helps very little and i can adjust the dpi on the mouse. Recently, on certain FPS games, I've noticed that it has diabolical accuracy when it comes to moving the mouse a millimeter. When i try to move the mouse a tiny amount, it just jumps across and misses a few pixels between the two points, making precision headshots at range very difficult. Is it the mouse that sucks, or the settings? Currently running it below max at 3600dpi and i generally turn the sensetivity down in game. I've turned off all the microsoft rubbish and left the sensetivity in that menu to the middle of the bar. Tempted to get a new mouse to alleviate my frustration.
