What eDPI is
eDPI is short for effective DPI: mouse DPI multiplied by in-game sensitivity. It exists because DPI on its own says nothing about how fast you turn. A player on 1600 DPI with 0.2 sens and a player on 400 DPI with 0.8 sens both have an eDPI of 320, and in the same game they aim identically. When someone asks what sens a pro uses, eDPI is the number that answers it without also asking about their mouse.
Two things eDPI does not tell you. It ignores Windows pointer speed and any acceleration, which is why both should be off or at default (the mouse settings guide covers that). And it does not carry between games, which is the next section.
Why the same eDPI turns a different amount in every game
Each game multiplies your sensitivity by its own yaw value, the degrees of turn per mouse count. Valorant's yaw is 0.07, CS2's is 0.022, Overwatch's is 0.0066. So 320 eDPI is a 40.8 cm full turn in Valorant and a 130 cm turn in CS2. The number that does carry between games is cm/360, the physical distance for one rotation, and that is what the pane shows next to your eDPI. The third column below is your own distance expressed as each game's eDPI.
| Game | Yaw | Your eDPI here | Pro range at 800 DPI |
|---|---|---|---|
| Valorant | 0.07 | · | 0.25 to 0.45 sens, 200 to 360 eDPI |
| CS2 | 0.022 | · | 0.8 to 1.3 sens, 640 to 1040 eDPI |
| Apex Legends | 0.022 | · | 1.0 to 2.0 sens, 800 to 1600 eDPI |
| Overwatch 2 | 0.0066 | · | 4 to 7 sens, 3200 to 5600 eDPI |
| CoD / Warzone | 0.0066 | · | same scale as Overwatch 2 |
| Deadlock | 0.044 | · | half of your CS2 sens for the same turn |
| Fortnite | 0.005555 per 1% | · | percent slider; compare by cm/360 |

To move a sensitivity from one game to another without changing how far your arm moves, use the sensitivity converter; the pair pages such as Valorant to CS2 show the math.
How to change your eDPI
Change either factor. DPI is set in your mouse software or with the DPI button on the mouse; most players leave it at 800 or 1600 and tune the in-game value instead. Sensitivity lives in the game:
- Valorant: Settings, General, Mouse Sensitivity: Aim, three decimals.
- CS2: the console or autoexec.cfg, the
sensitivitycommand, up to five decimals. - Apex Legends:
mouse_sensitivityin settings.cfg, or the in-game slider. - Overwatch 2 and CoD: Options, Controls, Mouse Sensitivity, a 1 to 100 scale with two decimals.
- Deadlock: its own autoexec.cfg under citadel/cfg, same command as CS2.
- Fortnite: Settings, Mouse Sensitivity X and Y, as percentages; set both the same.
Change it in one step, then test: a round of Flick at the old value and a round at the new one, and let the accuracy and reaction time decide. The sensitivity guide has the full method.
Questions
What is eDPI?
eDPI stands for effective DPI: your mouse DPI multiplied by your in-game sensitivity. It exists so two players with different DPI and sens values can compare how fast they turn. 800 DPI at 0.4 sens and 400 DPI at 0.8 sens are both an eDPI of 320 and aim the same.
Is a lower eDPI better?
Lower eDPI means more mouse travel for the same turn, which makes small corrections easier and fast 180s harder. Most Valorant pros run 200 to 360 eDPI and most CS2 pros 640 to 1040, but the right value is the one your desk space and play style allow. A trainer round at two settings tells you more than any pro's number.
Can I compare eDPI between games?
Not directly. Each game turns a different number of degrees per mouse count (its yaw), so 320 eDPI in Valorant is a 40.8 cm full turn while 320 eDPI in CS2 is 130 cm. Compare cm/360 instead; this calculator shows it for every game, and the sensitivity converter carries a cm/360 between games.
How do I change my eDPI?
Change either factor. DPI lives in your mouse software (or a DPI button on the mouse); sensitivity lives in the game: Valorant under Settings, General, Mouse Sensitivity: Aim; CS2 in the console or autoexec.cfg as sensitivity; Apex as mouse_sensitivity in settings.cfg; Overwatch 2 under Options, Controls; Fortnite under Settings, Mouse Sensitivity X and Y.
