In Device Manager for the mouse device, up the sampling rate.  Also up the
buffer size.  If those don't work, get a different cordless mouse.  Some are
very crappy.

When my Logitech cordless got damaged, I decided to try some other cordless
mice.  IBM's (which is made by someone else, don't remember) would go into
sleep mode far too quickly and its polling rate while sleeping was too slow,
so I would be moving the mouse a lot before it finally got shook enough to
wake up.  Microsoft's cordless took a bit longer to go to sleep (to consume
battery power) but was also slow to wake up.  By slow, I'm talking about one
to one and a half seconds.  Both the IBM and Microsoft were jerky in games
despite upping the sampling rate and/or buffer size.  I ended up returning
each after trialing them and went back to the Logitech (which is heavier
because of using AA batteries instead of AAA so it was more fatiguing to my
pinky having to squeeze the mouse to constantly lift and move it, and why I
decided to hunt around for a lighter but just-as-good cordless mouse).  So I
tried leaving Logitech but came back.  Eventually I decided to go with a
corded mouse.  As long as the cord doesn't bang against anything (to create
torque on the mouse) and the cord is free to move then I find it easier to
handle then the heavier cordless mice with their battery weight and having
to deal with erratic behavior when the batteries get low.
