Comparable results
Use physical cm/360, eDPI where appropriate and repeatable browser tests instead of relying only on a slider number or an impression that a setup “feels different.”

01 / Platform
One practical workspace for the settings behind competitive FPS play
FPS setup work is often scattered across a calculator, a click tester, a controller utility, a monitor page and several game-specific references. ZeroedTools organizes those jobs around the questions players actually ask: Is my sensitivity equivalent in another game? Is my input device behaving correctly? Is my display refreshing as expected? Can I reproduce a measurement after changing hardware or settings?
Immediate browser access
Open a test on the computer you are setting up without adding another download. That makes quick checks useful at home, at a LAN setup or after changing a peripheral.
Browse the gear lab →Tools plus current FPS context
The global news center tracks noteworthy patches, competitive events and releases so players can connect a new result or setting change with what changed in the games they follow.

FPS tools grouped by the problem they solve
Each destination below opens the live English version of ZeroedTools. The tools are designed for focused checks, so you can start with one measurement and move to a related test only when it is useful.
Sensitivity, cm/360 and aim
Convert game sensitivity while preserving the same physical turn distance, compare settings with eDPI inside the same game, then use aim and reaction tests to evaluate the result instead of copying a raw slider value between different engines.
Gaming mouse diagnostics
Check polling behavior, estimate DPI movement, measure clicks per second and look for unintended double clicks. These tests help separate a game setting problem from a peripheral or operating-system input problem.
Keyboard and controller checks
Visualize keyboard input, controller buttons, analog stick position, drift and deadzone behavior. Use the results when calibrating a new controller, checking an aging stick or confirming that a key is detected consistently.
Display and performance tests
Confirm reported refresh rate, inspect frame delivery and display common test patterns for dead pixels, ghosting and backlight bleed. Browser checks cannot replace laboratory hardware, but they are useful for repeatable first-pass troubleshooting.
Visibility and perception
Explore enemy visibility, contrast and motion-related display behavior in controlled pages. These tools are intended to help players compare configurations and recognize what changes when a visual setting is adjusted.
Delta Force companion area
Alongside the general FPS toolkit, ZeroedTools maintains a separate Delta Force community vertical with gunsmith data, maps, codes, operators and community features. It is an additional area, not the main identity of the cross-game tools platform.
03 / Supported games
Cross-game sensitivity support for widely played shooters
The sensitivity workspace covers popular competitive FPS titles that use different internal sensitivity scales. Matching cm/360 provides a physical reference when moving between games, while eDPI remains most meaningful when settings are compared inside the same title.
04 / How it works
Browser measurements, transparent limits and no required installation
What happens in the browser
Interactive tests use browser input, timing, graphics or gamepad capabilities to calculate and display a result on the page. Sensitivity tools apply documented conversion relationships and physical-distance calculations. Saved preferences can be reused by supported features without turning a simple test into a software installation workflow.
Browser timing depends on the device, operating system, browser, background load and display pipeline. For that reason, ZeroedTools presents these utilities as practical diagnostics, not laboratory-certified instruments.
Privacy and account requirements
The core public tests can be opened without a download or paid subscription. Test input used for an interactive browser measurement is handled by the tool running on the page. Standard website analytics, optional online features and any information a visitor intentionally submits are described in the main site's privacy policy.
05 / Typical use cases
When a quick, repeatable test is more useful than guessing
Preserve a familiar turn distance
Record mouse DPI and source sensitivity, convert to the target game, then verify the result in-game. A physical cm/360 reference avoids assuming two equal slider numbers produce equal rotation.
Check peripherals after a change
Test mouse polling, click behavior, keyboard input, controller drift or reported refresh rate after a new device, firmware update, cable change or operating-system adjustment.
Narrow down an inconsistent feeling
Run related tests one at a time to separate sensitivity, input, frame pacing and display symptoms before changing several settings at once.
06 / Languages and news
Localized tool pages and a global FPS news center
ZeroedTools provides locale-specific pages in English, Simplified Chinese, German, French, Portuguese, Spanish, Russian, Japanese, Korean and Indonesian. Language paths make it possible to share the relevant version directly instead of relying on a browser overlay.
The news center covers globally relevant FPS patches, esports events, releases and service changes. News is kept separate from the core tools so visitors can either open a measurement immediately or read the context behind an update that may affect their settings and play.

Common questions about ZeroedTools
What is ZeroedTools?
ZeroedTools is an independent collection of browser-based FPS tools. It includes cross-game sensitivity conversion, aim and reaction tests, mouse, keyboard and controller diagnostics, display checks and a global FPS news section.
Do I need to download or install anything?
No installation is required for the public web tools. Open the relevant page in a modern browser and follow the instructions shown for that test.
Why use cm/360 instead of copying the same sensitivity number?
Games interpret sensitivity sliders at different rates. Cm/360 measures the physical mouse distance needed for a full rotation, which gives you a shared reference across games. eDPI is still useful for comparing settings inside the same title.
Are browser hardware tests perfectly accurate?
They are practical diagnostics, not laboratory instruments. Results can be influenced by browser timing, device firmware, operating-system settings, background load and the display pipeline. Repeat a test under consistent conditions and confirm important findings with device or in-game settings.
Is ZeroedTools affiliated with a game publisher?
No. ZeroedTools is independent and fan-built. It is not endorsed by Riot Games, Valve, EA, Activision, Blizzard, Krafton, Epic Games, Ubisoft, Embark Studios, TiMi Studio Group, Tencent or other game publishers. Game names and trademarks belong to their respective owners.
Is the main ZeroedTools application open-source?
No. The live application is closed-source. The public GitHub repository behind this page contains only this independent static brand gateway and links to the live service; it does not contain the application source code.
