Dpi and sensitivity

post #1 of 27
Thread Starter 
I have a question is using `1800 dpi and 3 sensitivity as sensitive as 900 and 6 sensitivity. This spi thing is confusing me. Thanks for your help guys

Yes, although I'd just go with the 900 dpi since you will get much less negative acceleration and the same speed.

As far as I know, no. DPI measures how accurate your mouse is, so regardless of what your in-game sensitivity is, using a higher DPI setting is better.

DPI/CPI does not measure your accuracy. All it measures is how small of movements the mouse sensor can detect. It's physically easier to be accurate with a lower CPI/sensitivity as you have more room irl to hit the same size target onscreen.

You basically want a 1:1 ratio counts(dots) to pixels of movement at a CPI that feels right to you and it's best to set this at a hardware level as anything other than 6/11 can cause unwanted side effects in windows and lowering or increasing the sensitivity in game beyond a certain point can cause problems too, eg anything below around 1.8 sensitivity in Counter-Strike causing deceleration.

Because linear 1:1 is obviously best, you don't really need that much DPI. Consider your standard 90 degree field of view in an FPS. That's horizontally 1920 pixels at 1080p. A 180 degree heel turn is 3840 pixels of movement. Even if you are a high sens player, you don't need more than say 1800 DPI (a little more than 2 inches for 180) as otherwise hitting anything will be impossible. Too low a DPI for your sensitivity preference can cause pixel skipping unless you turn on acceleration, when you'll have trouble hitting anything.

I personally find 400 DPI to be fine at 1440x900.

400 DPI is the most widely used setting by comp FPS gamers. They're still using their Mx518 / MSIE 1.1 (or 3.0) and laugh at everyone who buys a new laser mouse.

Laser mice don't track well

Because he said the same thing I did, in the manner that made me think he misread my post.
