CS:GO eDPI kalkulator

DPI stands for dots per inch, referring to how a computer mouse measures physical distance. The more technically accurate phrase is actually CPI, or counts per inch, as dots are not actually used as part of the process. However, DPI is the abbreviation you’re more likely to encounter when comparing options, so we’ll be using that going forward.

You can find and change your sensitivity in CS:GO settings, or by typing sensitivity into your CS:GO developer console.

TL;DR: basically, if you have your windows mouse settings at 6/11 and smoothing off raw input will not effect your sensitivity at all. What it will effect are "feel", which honestly might be a placebo. I recommend trying both and just using what you feel best from a blind test (have someone else change the settings for you and don't look at them)

You can change this by typing m_rawinput "1" into your developer console in CS:GO. "1" means on, "0" means off.

Applies only if m_rawinput is off.
Can be found and changed by pressing Windows + R and typing main.cpl. Run the script and click on Pointer options tab.
