Oh, I'm not sure what you mean.
But before I read this guide my windows mouse sensitivity was at more than 6 (i think around 8 or 9) and when I tried doing the looping circles test in MS paint I was getting very rough jagged edges and occasionally mouse skipping which was annoying but got used to it.. So i tried setting windows mouse sensi at default of 6.. and voila! I get smoother (but slower) mouse movement
in-game i can use high sensitivity, so im ok with it, but in windows.. i'm stuck with the 6. oh well, better "slow but precise", than "fast but sloppy"
I didn't uninstall my Razer Deathadder drivers, but I've set my polling rate at 1000mz and dpi at 1800. The rest is untouched (x/y sensitivity is at max of 10 -- i think this is the default speed, even without the drivers installed).
