here are some important criterions that will tell u if a mouse is good or not.shape/grip
: it should be comfortable, at least.side buttons
: your choiceweight
: lower is better. under 85 is excellent, under 95g is good. Everything over is what I call a brick mouse.perfect control speed
: higher is better. no less than 2m/s. Yes, that means no WMOs.lift off distance
: lower is better. less than 2 CD is good.correction/prediction
: a little bit isn't the end of the world. it's up to you.acceleration
: none is better. accel in ur games is up to you, but accel from ur mouse is bad bad bad.cpi
: should have a setting around 800-1000cpi. Around ~500CPI might make you uncomfortable. On the other hand you get no benefit from more cpi. There's a formula quoted below that explains this.polling rate
: not very important, but preferably support for 500Hz, with HIDUSBF if necessary.wired/wireless
: you won't find a wireless mouse that meets the above measurements.
that's it. Now have a look at THE STICKY
and go crazy
Here's the formula that lets you know how much cpi will actually be useful to you.

minimum mouse cpi required = (in-game resolution width in pixels * pi) / ( number of inches it takes you to turn 360 degrees in-game * tan(in-game field of view / 2))
Example #1 with Quake Live settings.
In-game resolution width in pixels = 800
number if inches per 360 degree in-game turn = 10
in-game field of view = 120
800*pi / (10*tan(120/2)) = 146 cpi required. The wmo has 400, so I'm ok.
Example #2 with Crysis Wars settings.
In-game resolution width in pixels = 1920
number if inches per 360 degree in-game turn = 20
in-game field of view = 60
(1920*pi) / (20*tan(30)) = 523 cpi required, so 400 is not enough for perfect pixel accuracy. My options are to increase cpi, lower resolution, increase field of view or lower in-game sensitivity.
None of these values approach anything near the ridiculous cpi values advertised on today's crappy mice. That's right. high cpi is just a gimmick!
