FAQ

1. Mouse DPI & Sensor Calibration

Understanding optical hardware resolution for gaming.

What is the best mouse DPI for competitive gaming?

800 DPI or 1600 DPI is the consensus choice across modern competitive esports. 800 DPI provides an intuitive desktop cursor speed, while 1600 DPI reduces sensor start-of-motion latency by 2–3 ms.

Does higher DPI mean better aim?

Not automatically. High DPI increases coordinate sampling resolution, but overall crosshair accuracy depends on your combined effective DPI (eDPI) and physical hand control.

Why do so many professional CS2 players still use 400 DPI?

Many veteran pro players started competing on legacy optical mice (like the Microsoft Intellimouse 3.0) which only supported 400 DPI. They preserve 400 DPI to maintain decades of visual and muscle familiarity.

FAQ

2. In-Game Sensitivity & eDPI

Calculating effective sensitivity and matching aim settings.

What is eDPI and how do I calculate it?

eDPI stands for Effective Dots Per Inch. It is calculated by multiplying your mouse hardware DPI by your in-game sensitivity slider value (eDPI = DPI × Sensitivity).

Can I use my CS2 eDPI directly in Valorant or Overwatch 2?

No. Because each game engine uses a different base camera rotation factor (yaw), eDPI values are only valid within the same game. To match crosshair speeds across games, use our cm/360 Calculator.

How do I change my DPI without changing my in-game sensitivity?

Use the formula: New Sensitivity = (Old DPI × Old Sensitivity) ÷ New DPI. For example, moving from 800 DPI @ 1.0 Sens to 1600 DPI requires setting your in-game sensitivity to 0.5.

FAQ

3. cm/360 & Cross-Game Muscle Memory

Universal physical turn distances across different game engines.

What does cm/360 mean?

cm/360 represents the exact physical distance in centimeters your mouse must travel on your mousepad to perform a full 360-degree rotation in a 3D game.

What is a typical cm/360 for tactical shooters?

Tactical shooters like Counter-Strike 2 and Valorant reward deliberate precision, with typical competitive ranges falling between 35 cm and 55 cm per 360-degree turn.

What is a typical cm/360 for fast-paced tracking games?

Fast arena shooters and battle royales (Apex Legends, Overwatch 2, The Finals) feature high verticality and rapid tracking, with players commonly using 25 cm to 38 cm per 360° turn.

FAQ

4. Polling Rate, Windows & Hardware

Operating system pointer multipliers, USB reporting, and raw input.

Does mouse polling rate affect in-game sensitivity?

No. Polling rate controls how frequently coordinate updates are sent to the CPU (e.g. 1000 times per second at 1000 Hz), but does not alter overall camera speed or physical turn distance.

Should I disable Enhance Pointer Precision in Windows?

Yes, always. Enhance Pointer Precision is Windows non-linear mouse acceleration, which distorts muscle memory by making pointer travel speed-dependent.

What is Raw Input in gaming?

Raw Input bypasses operating system mouse filters and cursor scaling, pulling unadulterated sensor coordinate packets directly from the hardware driver.
