What really is Mouse DPI?

[NitrousBullet]

I always thought it meant dots per inch, or pixels per inch - as in a 400 dpi mouse will move 400 pixels on your screen within an inch. I've confirmed this with my Logitech MX518, setting it in 400 dpi yields that result. I've tested this on MS Paint since it shows your coordinates.

However, some mice like the Naga, Xai, or Deathadder do not yield that result. If MY understanding of dpi is correct, then I'll call it TRUE dpi. I've found out however that the Deathadder's 450 dpi = 400, 900 = 800, and 1800 = 1600 true dpi.

So can an expert help me clear the haze here?

What you want to know that you already dont know ?

DPI stands for dots per inch, The higher the DPI the faster mouse moves with.

A high DPI will make your mouse very fast. So little scrolling and it goes a long way

the higher the DPI the faster the mouse is going to move and be more sensitive.

with little effort you use mouse but also must have gentle hand if your goin higher DPI anyhow.. hope that helps. gg brother and gl

So, did you even read my whole post or just took a glance at it? I'm guessing you're not the expert I was looking for to answer my question... =_=

No, the DeathAdder really does have DPI counts of 450/900/1800/3500, if you're getting something different its human error or placebo

more isn't always better though, if you have a mouse that only does 400/800/1600 that doesn't make it inferior to the DeathAdder's 450/900/1800.

DPI is indeed dots per inch. Think of the physical surface you move your mouse around on as a screen with variable resolution. In a hypothetical extreme, imagine your mouse was 1 DPI - you would have to move the mouse an entire inch for it to register one increment (this increment itself is controlled by your driver and OS settings) of movement. On the flipside, if your mouse was 100,000 DPI it could register practically microscopic increments of movement.

Basically it boils down to higher DPI = higher precision and accuracy. If you are a professional FPS player your muscle memory remembers exactly where and how to move the mouse (and quickly) to aim the crosshair at a specific point for that pixel-perfect headshot. Players will use a low sensitivity and high DPI (at least I do) so their hand movements are as controllable and accurate as possible on the screen.

lol no

as long as that 1DPI mouse sensor is exactly 1inch of movement = 1 pixel of movement then it is just as accurate or precise for aiming as a 100,000DPI muse, its just not as fast

many, if not a clear majority, of professional gamers that require high precision from their mouse use a low DPI in the 400 range

edit: the guy above me is right, guess I had the wrong idea about DPI!

yeah i was under the impression that it meant the range in which the mouse track eye moved.

But true DPI vs normal also confused me.

Im guessing its a internal correction of some kind, so it gives actual DPI, and not a hypothetical one.

Of course i could be wrong.. but i was wondering about the same thing on razor products myself.

some mice use some sort of post processing calculations to interpolate a particular DPI

for instance I believe the Xai's DPI can be configured anywhere from 1 to 5001 DPI in increments of 1, but its "true" DPI occur on intervals of 90, so while its possible to configure that mouse to have a DPI setting of 1337, that is an interpolated state whereas a natural state would be any multiple of 90, so a better alternative would be to use 1350 as that would be a direct multiple of 90 and require no interpolation
