Reaction speed is the time between a stimulus appearing and your first physical response. In esports it determines whether you trade, beat, or get beaten on the first input. It is one of the most concrete cognitive measurements available to competitors, and the most reproducible.

Reaction speed is not the only variable that matters, decision quality, aim precision, and composure each add independent value, but it is the bottleneck beneath all of them. A player with elite composure but 320ms simple RT will still lose duels they should win because their mechanics cannot execute what their mind correctly reads.
At the professional level, the 90th–99th percentile range (168ms to 130ms) is where differences become visible in VOD review. Frame-by-frame analysis of elite play shows consistent sub-200ms responses to auditory and visual cues in unscripted combat, well below the population median.
The relationship to rank is not linear. Once you exceed the 90th percentile, additional milliseconds buy diminishing returns, and the limiting factor shifts to decision quality and composure. Below the 50th percentile, raw reaction speed is almost always the dominant bottleneck.
Hardware matters. A 144Hz+ monitor, wired peripherals, and a consistent high frame rate can shave 10–20ms of physical lag before your nervous system is even involved. The cheapest reaction-speed gain available.
Simple RT is sensitive to arousal state. Dedicated reaction drills for 5–10 minutes before a session move scores meaningfully, often 15–25ms, by priming the motor pathway. The warm-up is the training, not just preparation for it.
Ranked play trains reaction time incidentally. Isolated drills that force high-frequency simple reactions, aim trainers, dedicated RT tools, produce faster gains per hour than general gameplay. Quality of repetition beats quantity.
Improvement is only meaningful if you are measuring the same variable in the same conditions. A repeatable benchmark like the NeuroRank combine lets you track progress over weeks and months without chasing noise.
