What eDPI Can and Cannot Tell You

eDPI (DPI × in-game sensitivity) is a comparable number only within one game: CS2, Valorant and Overwatch each have their own sensitivity scales, so an eDPI of 800 in one says nothing about another. Pros cluster between roughly 400 and 1,600 eDPI in tactical shooters — low enough for crosshair precision, high enough for turns.

If you want your aim to survive a game switch, match cm/360° instead — that is the physical distance your hand travels for a full rotation, and it is the metric the sensitivity converter uses.

Quick eDPI Equivalents at Common DPI Steps

• The same eDPI at different DPI: 400 DPI × 0.70 = 800 DPI × 0.35 = 1600 DPI × 0.175 — all 280 eDPI, all the same in-game turn distance.
• Higher DPI with lower sens reduces sensor interpolation artifacts on some older mice, which is why many competitive players prefer 800–1600 DPI over 400.
• Windows pointer speed should stay at the 6th notch (1.0 multiplier); moving it makes the DPI × sens math stop matching your real cursor movement.

Changing mouse DPI without changing your aim

eDPI is useful precisely because it survives a hardware change: it is the product of DPI and in-game sensitivity, and that product is what determines how far the crosshair turns per unit of mouse movement. Change mouse, desk or refresh rate, and keeping the product constant keeps the rotation identical.

The practical case is landing on a native sensor step. Most mice track most accurately at fixed steps (commonly 400, 800, 1600, 3200), so players often raise the DPI and lower the sensitivity together — the slider moves, the product does not, and your aim stays where it was.

What eDPI does not include

• Polling rate and USB report interval — two players on the same eDPI with different polling rates do not receive identical input streams.
• Mouse acceleration and OS pointer interpolation — these change the relationship between physical movement and cursor movement outside the game’s own sensitivity value.
• ADS, scope and sniper multipliers — most games scale sensitivity when aiming down sights, so the effective eDPI while scoped is different.
• Field of view and monitor distance — the same eDPI feels different at different FOV settings, which is why FOV sits in the same tuning cluster.
• Equal eDPI means equal turning maths, not equal comfort — grip style, desk space and aim style (arm vs wrist) decide the right range for you.
