Mouse Acceleration

Whats up with the mouse acceleration in OSX(I'm using Lion)? When I use my logitech mouse with my PC it feels fine but when I use it with my mac it seems to move extremely slow when I just want to move it a little bit. This doesn't happen in windows. It's extremely frustrating and I can't figure out how to get it to not be so crappy. Its the logitech MX, I also noticed their is no mouse control app from logitech for OSX just Windows.
