using my mx518 at 1800 dpi now, but somehow i keep thinking when testing that 800 dpi is "better" for qw, and 1800 dpi is "too much" for qw ...


also read somewhere that a certain dpi on mouse is best to use in a certain resolution , i have the option to adjust dpi in X and Y axis in the mouse drivers,


what about if i make 640x480 dpi in 640x480 resolution, does this somehow benefit me? :E


any feedback appreciated 8)

I think lower dpi is more stable and less shaky. I use 900 dpi which is half of my max 1800.

What DPI really means when it comes to gaming, is accuracy.

Basically:

- 800dpi, sensitivity 10 (for 2*360 turn on your mousepad (an example!))
- 3200dpi, sensitivity 2.5 (same sensitivity ingame as above)

The higher DPI setting will allow you to make SMALLER aim corrections ingame. For example if you use the 800dpi example, let's say you can move your crosshair by one pixel with the smallest mouse movement. If you use 3200dpi example, you can actually move the crosshair less than one pixel with the smallest mouse movement.

It's easy to test yourself with ezQuake. Just try to move your crosshair the smallest amount possible with 800dpi and then with higher dpi. You get the picture actually better if you use as low dpi as possible vs as high dpi as possible, but don't forget to tune the ingame sensitivity properly.

I think it's questionable if you can intentionally make smaller adjustments than 1/32mm (800dpi) with your hand? At least for me the max dpi of a laser mouse kinda felt like it's registering "noise", movement that I don't really mean. Somehow lower dpi just felt more snappy and stable... Maybe there was something else wrong with the settings, dunno.

I don't really mean it like that. Let's take an example:

You have such a sensitivity, that allows you to turn 360 degrees with 50cm mouse movement. Whatever the distance there is for the smallest movement in the screen, it causes your crosshair to jump certain distance (let's say that's the 1 pixel mentioned before). Now, with considerably higher DPI you can see many very small jumps using the same distance you moved the mouse before the 1 pixel comes fully travelled.

See the point now?

Thanks Renzo and blAze.


hmm more tweaking I guess...

My recomendation: use minimal DPI that not gives visual steps in case of slow mouse moving.

Its all fake about DPI on mouses.
Controller compares very-low-resolution pictures getting from sensor (30x30 pixels)
to define by "some alghoritm" how it been moved. Than faster controller can checks images
- than more fidelity mouse gives to you. Physical, real DPI of optical mouse is very low, not more than 100 DPI.

So actually optical mouses dont have real dpi at all, basically typed "DPI 4000" means that alghoritm in that mouse
have increased range of speed, that not means accuracy, its sensitivity of even acceleration+sensitivity
