NVIDIA Reflex Latency Analyzer Mice Database

NVIDIA Reflex Latency Analyzer is a system latency measurement device designed to help gamers measure the responsiveness of their PC. By detecting clicks coming from your mouse and measuring the time it takes for the resulting pixels to change on screen, NVIDIA Reflex Latency Analyzer can break down the latency in your system.

Mouse latency is a critical part of the system latency equation: Mouse Latency + PC Latency + Display Latency = System Latency. The database in this repository contains the set of tested mice that NVIDIA has validated; containing both Reflex Latency Analyzer compatible mice, and popular non-compatible mice.

There are three categories of mice:

1. Reflex Latency Analyzer Compatible - Supports NVIDIA’s the dynamic click report extension
2. Non-Compatible - Does not support the dynamic click report extension, but can still report a database average
3. Unsupported - Mouse does not exist in the database

This database is used by the Reflex Latency Analyzer to identify mice and provide a database average when the mouse does not support per-click latencies.

Contents

This repository contains an Excel Workbook consisting of popular Esports mice, mice attributes, and left mouse button click latency.

Column	Description	Example
make	Brand	Logitech G
model	Product	PRO X SUPERLIGHT (wired)
vid	Vendor ID	046d
pid	Product ID	c094
revision	Firmware version tested (BCD Device ID)	2500
mode	<wired / wireless> - Whether the mouse is operating wired or wirelessly	wired
type	<wired / wireless / none> - Reported through the USB Extension - Implemented by the mouse manufacturer - This field can be "none" if the vendor is not using our extension	none
reportExtensionId	<TRUE / FALSE> - If the mouse reports PID, VID, and Revision extension - This is used by the mouse vendor to indicate a different PID and Revision in cases where the device	FALSE
perClickLatency	<TRUE / FALSE> - If the mouse firmware implements per click latency	TRUE
polledActuation	<TRUE / FALSE> - If the mouse uses polled actuation - An example of this is an optical switch that pulses the detection laser	FALSE
pulseFrequencyHz	Zero unless the mouse uses polledActuation - How often the mouse checks to see if there was a click - This measurement can only be taken with an oscilloscope	0
actuationDetectionDurationHz	The amount of time the mouse will accept a click per cycle - For optical mice, this is the amount of time the detection light / laser is on	0
maximumHosePollRateHz	Maximum polling rate supported by the mouse	1000
avgLmbLatencyUs	Average latency of 500 clicks	808
stdDevUs	Standard deviation of 500 clicks	302
adjustedAvgLmbLatencyUs	((1000 * (pulseFrequency / maximumHostPollRate) - actuationDetectionDuration) / 2) + avgLMBLatency	808
TestedBy	Who tested the mouse - NVIDIA only for now	NVIDIA
