Mouse negative acceleration.

[Rots]

Hi everyone,

I have this problem concerning my mouse: (please someone explain me if i'm wrong about gaming mouse concepts cuz i'm quite noob into this)

Lets say I set 500dpi and 1 ingame sensitivity. I do 360º in about 30 cm.
If i set 2000dpi and 0,25 ingame sensitivity, I have the same 30cm for 360º (sounds logic no?)

Well, the problem comes when I do my 360º turn faster on higher than 500dpi. Looks like there is some kind of data loss because it never reaches 360º on 30cm as it does slowly (or negative acceleration). (I'm not being extremely fast, not more than rocket jump flickshot)

Also, I tried to set my mouse to 4000dpi and 0,125 ingame sensitivity and it moves nice on slow moves but when I move my mouse faster, there's like a massive mouse lag.

I tried setting different polling rate (from 250 to 1000hz) and same results.

My windows (7) settings have no acceleration and cursor speed is set to 6/11
The mouse it's a krom khanda (new) avago optical sensor

Sounds like that mouse cant actually handle fast movement on such a high dpi setting. Coulde be caused by the surface of your mouse mat or just a bad mouse. For example in the Roccat mouse I had, the 3200dpi was actually just 1600dpi * 2. The cursor moved two pixels at a time Another issue I had was with a Mad Catz R.A.T 3 which had more acceleration to the right than to the left, but surprisingly had the most symmetrical acceleration on the highest dpi setting.

Anyways, I dont see any reason using a higher setting than 500. 500dpi is already 500 dots per inch or ~20 dots per millimeter, one dot being 0.05mm. So if you move your mouse 0.05mm, the sensor is able to recognize and transmit that movement to the computer.

Thx for the answer I think i'll use 1000dpi (no such pixel loss on fast moves) and a 500dpi switch for far range lasers
