I need to configure my deathadder.
Driver/ No Drivers
1800/900/450 DPI
Windows Sens
Hertz

n0thing settings
No Driver
1800
3/11
1000Htz

My settings
Driver 1.28
450
6/11
1000Htz

Btw im a lower sens user playing at 800x600.
Im scared to switch to n0thing settings because this guide
http://www.overclock.net/computer-peripherals/173255-cs-s-mouse-optimization-guide.html
says that anything other than 6/11 is inaccurate. Its a pretty well known and respected mouse guide.
"Lowering the setting here, throws away dpi from the mouse forcing you to use a use a higher, less precise sensitivity in-game."
Whats your input?

no one know anything about the deathadder in these forums?
