Mambasnake Laboratory White Paper: Gaming Mouse Click Latency Testing Methodology

Testing Disclosure and Conflict of Interest Statement

Transparency Notice: This evaluation was conducted by Mambasnake Laboratory, the engineering division of the manufacturer for the M5 Ultra and M3 gaming mice included in this test. While we maintain rigorous, deterministic testing protocols using industry-standard equipment (Tektronix/Nordic), readers should be aware of this inherent conflict of interest. All competitor samples (Razer, Logitech) were purchased through retail channels to ensure they represent production units available to consumers. We encourage readers to consult independent third-party reviews and conduct their own verification before making purchase decisions.

I. Executive Summary

In the signal pipeline of professional e-sports, Click Latency—the total duration between a physical switch actuation and the operating system receiving the interrupt—is a critical variable. As display refresh rates exceed 500Hz, input latency bottlenecks shift from the display to the peripheral.

This report documents the comparative testing of six gaming mice across varying polling rates (125Hz to 8000Hz). Our objective was to quantify the "Physical-to-Packet" delay using a deterministic, hardware-level measurement system. The data indicates a clear stratification of performance correlated with polling rate and microcontroller (MCU) throughput, with top-tier devices achieving sub-millisecond response times.

II. Test Design and Methodology

To eliminate the "Human Factor" and operating system jitter, we utilized a hardware-in-the-loop (HIL) testing environment. This setup measures the raw hardware latency of the mouse, independent of PC processing time.

A. Test Objectives

1. Quantify Absolute Latency: Measure the time delta between physical switch contact and USB packet transmission.
2. Evaluate Polling Rate Impact: Determine the latency reduction provided by 2000Hz, 4000Hz, and 8000Hz modes compared to the 1000Hz standard.
3. Assess Consistency: Analyze the spread (min/max) of latency to evaluate firmware stability.

B. Laboratory Infrastructure

• Signal Acquisition: Tektronix MSO54 Mixed Signal Oscilloscope (10 GS/s sampling rate) for capturing electrical switch closure and USB D+/D- line activity.
• Actuation Mechanism: High-speed electromagnetic solenoid plunger calibrated to 55g ± 1g actuation force.
• Signal Interceptor: Custom FPGA-based USB analyzer to timestamp HID reports.
• Environment: Faraday Cage isolation; Temperature 22°C ± 1°C.

C. Measurement Protocol

Our methodology tracks the signal through three phases:

1. T0 (Mechanical Trigger): Solenoid impacts the mouse button.
2. T1 (Electrical Closure): Internal switch contacts bridge (verified via direct PCB probing).
3. T2 (Packet Arrival): MCU processes signal, applies debounce, and transmits USB packet.

Calculated Metric: $$\Delta L = T_{\text{Packet}} - T_{\text{Contact}}$$

III. Experimental Results (January 2026)

The following data represents the aggregate results from our latest test cycle. For comparative validation, we have included links to independent benchmarks from RTINGS, a leading third-party authority in peripheral testing.

IV. Technical Analysis & External Backing

1. The 8000Hz Advantage and "Eager" Debouncing

The Razer Viper V3 Pro (0.74ms) and Mambasnake M5 Ultra (0.91ms) validate the industry push toward high-frequency polling.

• Technical Backing: The QMK Firmware Documentation defines "Eager" debouncing as an algorithm that reports a contact change immediately. This technical principle allows the M5 Ultra to achieve sub-1ms speeds with mechanical switches by mitigating physical contact bounce through firmware optimization.
• Firmware Verification: Performance is contingent on the latest firmware versions, such as the Mambasnake M5 Ultra v0.0.6.0 and Razer Viper V3 Pro v1.14.00.

2. The 1000Hz Standard and Debounce Bottlenecks

The difference between the Mambasnake M3 (5.71ms) and the 8KHz models is largely due to conservative firmware debouncing.

External Correlation: Research published via ResearchGate confirms that MCU processing and internal firmware "wait times" often contribute more to latency than the USB polling interval itself. This explains why standard 1000Hz mice often hover in the 5-7ms range.

3. Professional vs. Office Architecture

The 24.21ms latency of the Logitech MX Master 3S highlights the gap between office-grade power saving and gaming performance. This tiering is consistently documented by NVIDIA Reflex benchmarks, which emphasize that high latency in office hardware is a product of aggressive sleep states and lower polling rates.

V. Practical Implications (Performance Tiers)

• Tier S (< 1.0ms): Viper V3 Pro, M5 Ultra. Ideal for 360Hz+ monitors.
• Tier A (1.0ms - 5.0ms): Logitech GPX 2. Industry standard for competitive play.
• Tier B (5.0ms - 10.0ms): Mambasnake M3, G305. Reliable for the general gaming population.

VI. Conclusions

Our testing, cross-referenced with methodologies used by RTINGS and TechPowerUp, confirms that 8000Hz polling yields verifiable reductions in latency. While the Razer Viper V3 Pro holds the absolute lead at 0.74ms, the Mambasnake M5 Ultra (0.91ms) proves that optimized mechanical switch implementations can rival optical technology in the sub-millisecond domain.
