Yes, this is the ONE TIME you use the driver disk that comes with the mouse. The new software apparently forcibly upgrades your mouse's firmware and does bad things (not sure for Deathadder).
You missed the point. The deathadder is not popular because it have tons of features (that are drivers dependant, which would then make sense), but rather because it host a sensor that is prediction and acceleration free.
You dont need to have the drivers installed to be able to use this feature, since it's hardware related.
The side button also work fine without the software.
Now, if we talk about their other mices, it become a different story. The synapse 2.0 software is crap, from my experience.
