G5 is just toooo fast for gaming

The new logitech G5 mouse which i have and really like comes with SetPoint a software that lets you adjust the dpi (dots per inch) and other settings specifically for each game, it works pretty well, you can see if you can download it here http://www.logitech.com/index.cfm/428/135&cl=us,en
the newer version of the G5 has two buttons behind the scroll wheel that let you adjust how much dpi you want with up too 5 different setings im not sure how the older one works. There is also a setting in the software that lets you decide whether more dpi means more movement or less and more precision. Also check in your windows settings and turn that down a bit, im not sure whether that still has influence on the mouse or if the logitech software works independently of that.

try a razer mouse
