Clear results, with honest limits

GameTools is built to solve one task without making you work through endless pages. Each tool includes input guidance, examples and caveats when a result is theoretical or depends on your device. Calculations run in your browser wherever the feature allows it.

How GameTools works →
A practical way to start

Go from question to result, without the detour

Choose a tool based on the decision you need to make. Enter realistic values, check the units and treat estimates as guidance when a factor cannot be measured by the browser.

1. Define the task

Are you tuning a shooter’s sensitivity, checking a power supply estimate or understanding download speed? Start with the job you need to do, not a list of technical terms.

2. Use comparable inputs

Check that units match. Mbps is not the same as MB/s, and eDPI can only be compared directly within the same game.

3. Read the result in context

Check each tool’s notes and example. Estimates for power, energy or transfer time do not replace manufacturer specifications or real measurements.
