If y our expecting just like pc performance, you you won't get it, but its as close as you can get...
Flicking 180degree turns is only possible in a few games...and even then only with an extremely sensitive config.
You can only turn as fast as the game will allow...AKA, you tried to cut a 360, and move your mouse your 17.5 inches quickly, you might move...2 inches on screen...to do 360's and 180's with an xim, you move the mouse quick, but once constant motion...not fast..not slow..just one speed like a smooth glide...hard to explain.
almost like...a deceleration. if you mvoe the mouse quick, one side of pad to the other, your xhairs move..1 inch, you move it slow, one side of mousepad to the other..youll do a 360...
