Pretty much. Skipping pixels isn't a big deal until a certain point though, depends on how-high sensitivity you play.

Is their a program i can get to test for this?

Why sensitivity 1.0 and not 0.5 or 0.1 or 3.0 or something else? Even with sensitivity 1.0 there will be "pixel skipping" with extreme high resolutions.

The real question is something like that: what sensitivity I need to be able to aim at whatever I want from farthest distance possible in certain game?

Screen resolution and mouse CPI are irrelevant.

What you mean they are irrelevant?

I was told in the first post that i need sens 1 in game and adjust dpi. So people are telling me 5 different things.

Pixel skipping on 1:1 ? That would be a faulty sensor/MCU/software or CPI interpolation. 1:1 without accel/interpolation/edge snapping provides exact 1 count/ 1 pixel movement.

With windows sensitivities lower than 1:1 (6/11) like 1:2 (4/11) you would need to double your CPI to get the same cursor speed... It is known that some sensor don´t behave as well with higher CPI mainly because it becomes more sensitive to irregularities on the surface so the only reason to use lower than 1:1 sensitivities is that your mouse has an specific issue with a certain CPI setting or doesn´t go as low as you want on CPI. For example the new Puretrak talent is going to be minimum 500 CPI so those 400CPI players may want to use 800CPI and use the 1:2 setting (4/11) as the performance of that sensor is practically the same on that setting... anyway some old games like CS had a minimum sensitivity of 1:1 so that option isn´t always possible.

It´s always smart to use the minimum CPI of your mouse in 1:1 unless you know about an specific CPI issue, then you might want to go lower on an exact factor so you don´t get an uneven pixel skipping. Pixels can´t be divided so your movement will be uneven from inch to inch if you go 1:1.33, for example, the first 2 counts will move 2 pixels and the 3rd count will move 2 pixels as well.

It´s never recommended to set sensitivities higher than 1:1 unless your mouse doesn´t provide enough CPI for you, then, again, it´s reccommended to go on an exact factor like 2:1 (8/11) and to set your mouse to half the desired DPI. Keep in mind that with the 2:1 setting your pixel movement resolution is only the half so you will skip half the pixels on your movement which results on a loss of precision.

Simply put, the way most engines interpret CPI can be determined by a formula. Sensitivity adjusts the speed of the cursor movement by a magnitude of the CPI, so if it is greater than 1, it is telling the engine to go beyond a few degrees of rotation (suppose the smallest degree you are able to rotate the camera by is 0.02 degrees at a sensitivity of 1, it'll move 0.09 degrees at a higher sensitivity note that is the smallest degree you can move, so obviously the higher your sensitivity, the larger the minimum degree the camera will move, hence less precise. - hypothetically since I do not have the formula at hand with me). Even simpler, in a 2D plane, having a sensitivity of 1 will mean the cursor will move 1 pixel per count, a sensitivity of 2 will move 2 pixels per 1 count, and so on. A higher resolution will require more CPI as the density of counts required is much higher, so this will affect how you adjust the CPI of your mouse. The two are VERY MUCH related.

Is their any program i can use to get my correct sensitivity?

I mean, when you set up sensitivity correctly so you can aim at everything at longest distance, then resolution doesn't matter. CPI isn't connected with pixel skipping.

I meant 3D fps game. You are right, in 2D it's true.
