Why is my 1000Hz mouse only showing 150Hz–300Hz when moving slowly?

Gaming mice dynamically lower their USB report rate when moving slowly or in straight lines to save power and bandwidth. To reach your mouse maximum polling rate (1000Hz, 4000Hz, or 8000Hz), move the mouse rapidly in large continuous circles.

What causes a mouse to double-click on a single press?

Mechanical mouse microswitches use a tensioned copper leaf spring. Over millions of clicks, oxidation or metal fatigue causes the contact to physically bounce ("chatter") for a few milliseconds upon press or release, sending two electrical signals faster than humanly possible (< 45ms).

How do I fix scroll wheel jumping in the opposite direction?

Reverse scroll jumps are caused by dust accumulation or worn contacts inside the mechanical rotary wheel encoder. Blowing compressed air into the wheel gap or cleaning the encoder with electronic contact cleaner often resolves the issue.

Q: How do I fix scroll wheel jumping in the opposite direction?

Reverse scroll jumps are caused by dust accumulation or worn contacts inside the mechanical rotary wheel encoder. Blowing compressed air into the wheel gap or cleaning the encoder with electronic contact cleaner often resolves the issue.

Measure real-time mouse USB polling rate (125Hz–8000Hz), detect faulty switch double-clicks, and test scroll encoders.

Technical Overview & Architecture

A high-precision hardware diagnostic suite for gaming and productivity mice. Captures sub-frame coalesced pointer events to measure real-time USB polling rate in Hertz (Hz), detects mechanical microswitch contact chatter (unintended double-clicks < 45ms), and diagnoses buggy scroll wheel rotary encoders.

Standard browser mousemove events are throttled to your monitor refresh rate (e.g. 60Hz or 144Hz). To measure high-speed gaming mice up to 8000Hz, our engine inspects PointerEvent.getCoalescedEvents(), which exposes every individual hardware USB interrupt queued between display frames.

Key Capabilities & Features

Sub-Frame Coalesced Polling Rate Engine: Reads raw PointerEvent.getCoalescedEvents() timestamps to measure 125Hz, 500Hz, 1000Hz, 2000Hz, 4000Hz, and 8000Hz mice.
Mechanical Switch Double-Click Detector: Measures exact millisecond deltas between clicks on Left, Right, Middle, and Side buttons to flag faulty switch bounce (< 45ms).
Scroll Wheel Encoder Skip Detector: Monitors continuous upward and downward scroll steps and flags sudden reverse-direction encoder glitches.
Live Hz Stability Graph: Real-time canvas telemetry chart plotting polling consistency, peak rate, and report interval delay in milliseconds.

Step-by-Step Usage Guide

Move Cursor Rapidly in Circles: Swirl your mouse continuously inside the dark tracking arena to saturate the sensor and read your Peak and Average Hz.
Test Buttons for Double-Click Chatter: Click normally on the test pad 20–50 times. Any unintended hardware bounce faster than 45ms will trigger a red fault alert.
Roll Scroll Wheel Up & Down: Scroll continuously in one direction to verify whether your rotary encoder registers any faulty reverse jumps.
