Adjustments

okay i might be annoying but just want to be sure everything is OK
i`m talking about my mouse settings
there some options i dont know what are for and if any of you know , please enlighten me

1st i want to know what is this option Pointer Acceleration is for
I have to chose between None -> Medium -> Low -> High
The Other one is this option Report Rate ( reports per second)
my default is 333 but i have other options 125 , 200 . 250 , 500 , 1000

and finally i have mouse sensitivity settings (dpi)
1 - 2000
2 - 800
3 - 400

i`m a newbie so please tell me the best config. for jumping
i know some of you may say that it matters little but still ..

Higher DPI = More accurate
