calculating your dpi

[Acrobat]

Found this on OW forums in a discussion on mouse sensitivity.

 

Basically EDPI = mouse sensitivity X dpi.

Therefor if you halve your mouse sensitivity you should be able to just double your mouse dpi to get the same EDPI. (EffectiveDPI) However, using somewhat higher dpi values with lower sensitivity seems superior bc of pixel skipping, which is determined based on what resolution you play at. If you're playing on 4K or 1440P you will need a higher dpi than a person playing on a 1080p monitor.

Public Service Announcement - low DPI

Low DPI isn’t good for your aiming.

DPI is only one component that translates to in-game aim. When combined with in-game sensitivity, the both of these are used to find something known as a “cm/360”, or the amount of mouse-pad travel (in centimeters) in order to turn 360 degrees in game.

People say “low DPI” because if you never touch your sensitivity values, you’ll have a really high cm/360 value – you’ll turn slowly, so you’ll be able to hit precisely where you want.

But, there’s a problem with using low DPI.

• A 400 DPI & 10 sensitivity combined has a 34.64 cm/360
• That same 34.64 cm/360 can also be achieved by 1600 DPI & 2.5 sensitivity

The difference here is that with a high DPI your mouse is feeding in 4 times the amount of mouse-pad travel to your computer, which then the game has to process.

This in turn means you get more more micro-degree turns out of a high DPI.

• One tiny millimeter of mouse movement with your mouse, will always move fractions of a degree on high DPI
• If you use a low DPI, sometimes millimeters will not be reported to the game and you won’t turn fractions of a degree. This is known as pixel-skipping.

Thus, having a low DPI is a mistake.

You need those micro-degree turns, especially when you’re playing a hitscan character. Thus, having a low DPI is a mistake.

Use this DPI calculator specifically for Overwatch to find your cm/360. The calculator tool also tells you which DPI/Sensitivity combinations will be prone to pixel-skipping.

Plug in your current values, and learn and memorize your cm/360. This value will be crucial in finding your perfect aiming turns in other FPS games.

If you see a bunch of red boxes on the lower section, it means you’re prone to pixel-skipping.

• Double your DPI and half your in-game sensitivity. Keep doing this until those red-boxes (at your monitor’s resolution) turn blue.
• Your cm/360 remains the same, but you’ve eliminated pixel-skipping from your setup

Also keep in mind that historically mice have native dpi that can be best to run them at or at least intervals of that native value. So if the native is 400 than it might run ok at 800. However the new mice tend to run native so long as you change the dpi in intervals of 50.
