"DPI is how small the detail the mouse can track; sensitivity is how much the software will move whatever is being moved in the direction the mouse is indicating."
That is what i was saying? Since it can recongnize more it is smoother, when on a high dpi it recongnizes more, there for is smoother, it doesn't have to move as much, so it is faster....Quote isn't working on this computer for some reason, thats why i did not quote the post.
I wouldn't mind getting the mouse, but i just got the lachesis, and to be honest, 1600 dpi isn't worth it for me, 4000 is good enough for now. I can already move over my entire 22" monitor in less then an inch of the mouse moving.
