Same-game sensitivity lab

eDPI Profile Workbench

Compare several mouse profiles, choose a reference, and model what-if changes without treating eDPI as a universal cross-game measurement.

Local only · no device access or network requests

How to use

  1. Name each profile and give truly comparable profiles the same game / scale label and entry type.
  2. Choose a reference to see exact eDPI differences and the sensitivity that matches it at every DPI.
  3. Set a percentage change to preview a target, then copy or export the workbench if useful.

What-if target

Applied to the reference eDPI

From −100% to +1,000%; decimal comma is accepted.

Comparison sheet

Profile Game / scale Inputs eDPI Vs reference Sens to match reference Sens for scenario

A “different scale” result is intentional, not missing data. Copy uses the clipboard only after you press the button. CSV export creates a local file and sends nothing away.

Formula, normalization, and interpretation

The workbench uses the number you enter, not an assumed game database. Leading and trailing spaces are removed, repeated spaces in names are collapsed, and decimal commas are normalized to decimal points. Mixed comma-and-point numbers, thousands separators, non-finite values, fractional DPI, and out-of-range values are rejected.

  • number entry: eDPI = DPI × sensitivity
  • percent entry: eDPI = DPI × percentage ÷ 100
  • difference % = (profile eDPI ÷ reference eDPI − 1) × 100
  • target sensitivity = target eDPI ÷ DPI (multiplied by 100 for percent entry)
  • The same normalized game / scale label plus the same entry type is treated as permission to compare. Check those labels yourself.
  • “Number as shown” is for decimal or numeric sliders. “Percent shown in game” converts a displayed value such as 7% to 0.07 before multiplying.
  • Matching eDPI within one linear scale can preserve the numeric product when DPI changes. Menu rounding, sensor DPI deviation, acceleration, and input processing can still alter real results.
  • No single eDPI is inherently good, bad, precise, or professional. Comfort, control, role, space, and the game all matter.
