I was wondering i someone could do some calculations for me. I was playing on a 4k monitor in 4k full screen, then changed it to 1080 size and my accuracy got much better. This is because I was moving my mouse less for the same distance, so what sensitivity would i want to change to on the fullscreen 4k to get the same accuracy? I was sniping with 500 DPI, 5 sensitivity for both. What do i change the 5 to, to get the results I want. I understand if nobody can give me an answer, but i figure someone knows more than me about this, and can calculate the info i need.
