and, you probably know this, but make sure m_accel or whatever is set to 0 in your settings..Assuming you have a logitech mouse, the logitech utility is setpoint or something, load that up and turn mouse accel off in the "game mode" part or whatever it says as well.
I get the crazy mouse spins every 5 mins or so. How can I fix this? I'm using a usb mouse and have "enchance pointer precision" on if that makes any difference.
change your mouse.
