Why Some Gamers Land Pentakills While Others Can’t: The Role of Critical Flicker Frequency

01 CFF and Animal Time Perception

The critical flicker frequency (CFF), introduced by Kevin Healy in 2013, measures the brain’s threshold for processing visual information. Humans have a typical CFF of 60 Hz, while other animals differ: turtles 14 Hz, dogs 80 Hz, squirrels 108 Hz, and flies 240 Hz. Higher CFF values give smaller animals a “bullet‑time” advantage, explaining why flies seem impossible to swat and why dogs perceive TV as flickering.

02 Impact of CFF on Human Life

Human CFF also changes with age. As people grow older, they handle more information, which slows retinal processing and makes subjective time feel faster. The article suggests that regularly reviewing and pruning mental “garbage code” can help retain useful logic and mitigate this slowdown.

Psychological states such as fear or stress can lengthen perceived time. Citing David Eagleman’s high‑altitude fall experiment, volunteers reported subjective durations about three times longer than the actual 2.6 seconds, yet they could not read a rapidly flashing timer, indicating the effect is subjective rather than objective. Eagleman labels this the “odd effect,” occurring when intense focus contracts perceived time.

03 CFF and Gaming Performance

Beyond physiological factors, elite gamers appear to boost their effective CFF during critical moments, enabling faster micro‑operations and reactions. Professional e‑sports players often use 144 Hz monitors, which align with their higher CFF, whereas a 60 Hz display feels sluggish to them.

The article mentions training approaches such as “slow‑fast running” used by baseball coach Mike Hall, which aims to put the brain into “the zone” and potentially enhance time‑distortion abilities. It concludes that while ordinary players can improve by focusing on persistence and precision, mastering high CFF remains a domain of top e‑sports athletes.
