bro somiao, or any1 here using ikari laser, i wan to ask that what is the freemove things setting in the ikari laser software.... i don understand what it write there maybe my english is poor...

Nah, you just dont understand the term, ntg wrong about your english, freemove disables prediction, prediction arh, hmm, i'll qute from fragyou,
"Prediction"
Feature: Prediction and correction of movement. Let’s say you’re trying to make a horizontal movement. Of course your hand isn’t 100% steady, so your line will have slight diversions and wouldn’t be completely straight. Back in the day, the manufacturers of mouse sensors decided to include a feature in the optical sensors of their mice, that would help people draw straight lines. It would “remove†the small diversions, if the diversion was less than a certain angle and instead just draw a perfectly straight line. The funny thing is: This feature has never been marketed, though it has been in countless mice over the past years. Can you guess why?
Problem: Prediction cost you precision. Period. If your mouse is trying to predict your movements, instead of just performing the movements you are actually doing, your precision is obviously degraded. If you want to make a movement that is almost, but not quite, a straight line (meaning you want to move a bit up and like half a screen to the right for example) then your movement will be altered. This function of sensors kicks in pretty fast and the worst part: in most sensors you can’t even disable it.
Solution: The introduction of SteelSeries FreeMove. This frees your movement from pre-calculated or altered movements imposed by your sensor. What basically happens is the following: As our sensor is programmable we let you remove (recommended), keep and even tune the settings of this particular feature. After conducting testing with gamers, it became painfully obvious that prediction should be optional. FreeMove allows the user to completely disable prediction– as well as utilize different degrees of prediction, as personal preference dictates. Again, this prediction “feature†has never been marketed, and we expect you will see several mouse companies remove the feature in the future now that we have brought attention to it. This will hopefully make future mice more precise for everyone.
Try drawing some lines in paint, you'll notice the difference, anyway, imho it doesnt rly affects precision or anything~
