What InputLab is on this Releases page

This GitHub Releases page lists InputLab, a Windows tool (binary-only) that inspects how evenly your mouse and controller reports arrive in Windows. The page summarizes multiple release notes (v1.0.0 through v1.4.0) describing features such as USB timing, a wireless mouse doctor, interrupt and driver checks, a USB map, and measurements shown as pictures. The page text also shows an error message from GitHub about loading the page in places.

What you can do with InputLab according to the release notes

Measure where mouse report gaps happen and which stage caused them: the mouse/receiver, USB interrupt handling, or Windows passing the report on late. See every driver your mouse reports pass through (the mouse path) and read driver stack names. Inspect interrupts per CPU core, view the USB work waits, waves of gaps and stacked-bar visuals, and compare before/after measurements. Use the driver check to name drivers that coincided with gaps and get guidance (including whether a documented fix exists). Edit an interrupt layout and test moving a device to a quieter core without writing changes until you choose Write. The tool produces a revised "fairer mouse score (v3)" for runs and keeps older saved runs' scores unchanged.

Who will find this useful

People troubleshooting mouse jitter, skipped reports, or unexpected input timing will find the tool targeted: it maps USB timing, interrupts, drivers and power settings that can affect reports. It also suits users who want detailed, low-level traces showing which driver or core handled mouse work, and those who want to test changes (driver updates, interrupt layout edits) and compare measurements. The page notes InputLab is binary-only and that it does not look up newer drivers because it has no network access.

Questions people ask about "Mouse settings don't affect FPS." Valorant player after InputLab

Can InputLab change my system settings automatically?

You can edit an interrupt layout and choose Write to apply it, but the layout editor does not write anything until you explicitly write.

Will InputLab tell me which driver version is installed?

Yes; the tool shows drivers as installed with their provider and version (for example, NVIDIA shown as NVIDIA numbers it) and where interrupt settings came from.

Does InputLab check for newer driver downloads?

No, the release notes say InputLab has no network access and does not look up whether a newer driver exists.
