Not heard that before. Where you see that?
A few forums around back when i used to play CS:S and also the Steel Series Advice states this:
Report rate (also known as
polling rate) determines the
number of reports sent every
second by your mouse to your
computer. Traditional mice
utilize a set number of
reports between the mouse
and the computer, locked to
set figures like 125, 500 or
1000Hz. SteelSeries
ExactRate allows you to
define a limit to this data and
you can allow it to
correspond to your in-game
frame rate and monitor
refresh rate for a
homogenous, synchronous
and consistently smooth
mousing experience. Set this
value to correspond to the
lowest value in either your
in-game frame rate or monitor
refresh rate.
Optimal use: If you utilize
a screen with 60Hz, you
should try setting this at
960Hz (or something else
that is dividable by 60).With
this setting your report rate
will be synchronized to the
refresh rate of your screen,
improving consistency and
smoothness of your
movements.
