What is eDPI and How Does it Calculate True Sensitivity?
eDPI (Effective Dots Per Inch) is the product of your mouse's physical sensor sensitivity (DPI) and your software in-game sensitivity multiplier. Because different players use different combinations of DPI and in-game multipliers, comparing raw settings can be confusing. Calculating your eDPI consolidates these two variables into a single comparative number. For example, a player using **800 DPI** with a **1.0 sensitivity** multiplier and another player using **400 DPI** with a **2.0 sensitivity** multiplier both have an eDPI of **800**. Their physical hand travel distance to rotate 360 degrees in-game will be exactly the same.
Converting Aiming Sensitivity Across Different Game Engines
Every game engine parses mouse inputs differently, scaling sensitivity sliders based on proprietary coefficients. To translate your muscle memory between titles, you must apply standard conversion ratios:
- Source (CS2 / Apex Legends) to Valorant: Divide your CS2 sensitivity by **3.1818**. (e.g. 1.5 in CS2 equals 0.471 in Valorant).
- Source (CS2 / Apex Legends) to Overwatch 2: Multiply your CS2 sensitivity by **10.6667**. (e.g. 1.5 in CS2 equals 16.0 in Overwatch 2).
- Valorant to Overwatch 2: Multiply your Valorant sensitivity by **3.3528**. (e.g. 0.4 in Valorant equals 1.34 in Overwatch 2).
The Difference Between Low and High eDPI Aiming Tiers
Players generally fall into two distinct mechanical aiming styles based on their eDPI profile:
- Arm Aiming (Low eDPI Tiers): Typically falling between **150 and 300 eDPI** (based on CS2 scales). These players use large sweeps of their entire forearm to rotate, using the wrist solely for micro-corrections. This style offers exceptional precision and consistency but requires a large mousepad.
- Wrist Aiming (High eDPI Tiers): Typically exceeding **400 to 800+ eDPI**. These players pivot their hand from the wrist or fingers, making small movements to rotate. This offers ultra-fast response times and works well in vertical games (like Fortnite or Apex), but makes micro-adjustments harder to execute consistently.
eDPI SENSITIVITY SOLVER FAQ
How do I calculate my exact eDPI?
Multiply your mouse's physical DPI (e.g., 800) by your in-game sensitivity value (e.g., 1.5). The result is your eDPI: **800 * 1.5 = 1200 eDPI**.
What is the average eDPI for professional FPS players?
In tactical shooters like Valorant or CS2, the average pro eDPI is relatively low, typically sitting between **200 and 320 eDPI** (CS2 scale) or **70 to 100 eDPI** (Valorant scale). In faster trackers like Apex Legends, average pro settings rise to **400-600 eDPI**.
Does screen resolution change my actual eDPI sensitivity?
No. Game engines process camera rotation using angle degrees per mouse count, which is independent of screen resolution. Your physical distance to rotate 360 degrees remains identical whether you play on 1080p, 1440p, or 4K, though the visual scaling on a higher pixel grid may make it feel slightly different.
Should I scale my sensitivity when changing Field of View (FOV)?
Ideally yes. Many games automatically apply focal length scaling (like ADS sensitivity scaling). However, if you increase your base FOV, target models will look smaller, and your mouse movements may feel faster. Adjusting your multiplier downward slightly can help restore spatial aiming consistency.
