I too had trouble with the Razer control panel - accleration was no good, but the tracking speed was too slow without it.
Then I discovered that the standard Apple mouse control panel in system prefs actually overrides the Razer control panel. So by using this, and putting the tracking speed to just the 4th notch, the mouse works fine without acceleration.
The only downside is that the Razer settings come back on if you restart your computer, so you need to open the mouse system pref panel and adjust the tracking speed again. I use an iMac which is rarely off, so I don't need to do this very often. For those using this with laptops, I guess you'll have to do it more frequently - unless you uninstall the Razer panel completely? I presume it has some behind-the-scenes loader, even though it is an app itself. My mouse remembers to keep the logo light off but the scrollwheel light on, so that must be stored somewhere (unless it's in the mouse itself).
With the Apple control panel, I've found the Deathadder to be absolutely perfect.
