Monitor refresh rate vs aim training effectiveness

By Mustafa Bilgic, FPS gaming enthusiast (Adiyaman, Turkiye) — last reviewed 2026-05-06.

Does 360Hz actually beat 240Hz for aim? The marketing implies a step change. The latency math implies diminishing returns. The published research lands somewhere in the middle. This piece walks through the numbers, the NVIDIA Reflex study, the perceptual literature, and gives a buying decision tree that respects diminishing returns.

Short answer. Going 60 → 144 Hz produces a large, measurable improvement in flick performance. 144 → 240 Hz produces a smaller but still meaningful improvement. 240 → 360 Hz produces a real but small improvement. 360 → 480+ Hz produces a marginal improvement that is best directed at lowering total system latency rather than refresh-rate-only gains.

1. The latency stack

End-to-end input latency is the sum of:

  1. Mouse-side latency: sensor sample to USB report. ~1 to 2 ms at 1000 Hz polling, sub-1 ms at 4000-8000 Hz.
  2. OS / driver latency: USB receive to game tick. ~1 to 3 ms on modern Windows builds.
  3. Game logic latency: tick to frame submit. Highly engine and FPS dependent. Average 0.5/FPS to 1.5/FPS seconds. At 300 FPS, that is 1.7 to 5 ms.
  4. Render queue + GPU pipeline: 1 to 30 ms depending on V-Sync, queue depth, NVIDIA Reflex / AMD Anti-Lag.
  5. Display latency: scan-out plus pixel response. At 240 Hz the half-refresh average is 2.08 ms; pixel response on premium IPS is typically 1 to 4 ms; OLED 0.1 to 0.5 ms.

Total commonly lands between 8 and 40 ms on tuned setups; 40 to 80 ms on stock setups. Refresh rate is one component, not the whole story.

Half-refresh interval table

Refresh rateFrame intervalAverage display delay (half frame)
60 Hz16.67 ms~8.33 ms
144 Hz6.94 ms~3.47 ms
240 Hz4.17 ms~2.08 ms
360 Hz2.78 ms~1.39 ms
480 Hz2.08 ms~1.04 ms
540 Hz1.85 ms~0.93 ms

The 240 → 360 step saves about 0.7 ms on average; the 360 → 480 step saves about 0.4 ms. These deltas are real but small relative to network jitter (1 to 3 ms) and game tick rate (often 64 to 128 Hz, that is 7.8 to 15.6 ms granularity).

2. The NVIDIA Reflex study

NVIDIA published an internal but well-documented study in 2020 (NVIDIA Reflex White Paper, replicated in independent reviews on TechPowerUp, RTINGS, Hardware Unboxed) that measured flick-shot accuracy as a function of total system latency on Kovaak's-style scenarios. The headline finding: each 10 ms of saved latency produces approximately a 4 to 6 percent improvement in flick accuracy and a similar reduction in mean reaction time.

The study held refresh rate constant in some conditions and varied refresh in others. The clear conclusion: total system latency matters more than refresh rate alone. NVIDIA Reflex (which reduces render queue depth) saved more latency in many scenarios than the 240 → 360 refresh upgrade.

Caveats: the study used flicks on Kovaak's-style targets, not all aim sub-skills; subjects were trained gamers; and the underlying data has not been peer-reviewed. Independent replications by hardware reviewers have reproduced the latency-to-accuracy correlation but with smaller effect sizes.

3. Perceptual literature on motion smoothness

The visual system handles motion as a sampling problem. The literature on motion perception (Burr and Ross 1979, Vision Research 19, 285-293; Watson and Ahumada 2005, Journal of Vision 5, 717-740) shows the human perceptual system can resolve flicker and stutter up to roughly 90 Hz under typical conditions, with edge cases visible up to ~200 Hz. Above ~200 Hz, motion smoothness improvements are largely unconscious — players do not see the smoothness, but they react slightly faster because the next visual update arrives sooner.

Translation: 144 Hz crosses the conscious-perception threshold. 240 Hz is well past it. 360 Hz benefit is mostly latency-driven, not visual-fidelity-driven.

4. Practical aim training implications

4.1 In aim training

Trainers like Kovaak's and Aim Lab cap CPU/GPU usage low, so frame rates run extreme (often 800+ FPS). The bottleneck is display refresh + pixel response. Switching from 144 to 240 Hz on the same monitor gives a measurable scenario-score lift (typically 2 to 5 percent in published reviewer tests). 240 to 360 Hz gives 1 to 3 percent in the same conditions.

4.2 In game

FPS games impose additional bottlenecks: server tick rate, network jitter, and engine queue. The refresh-rate benefit narrows. A pro on 240 Hz with NVIDIA Reflex and a 4000 Hz mouse on a 1 ms response IPS / OLED panel often beats a player on 360 Hz with V-Sync, slow pixel response, and 1000 Hz polling.

4.3 Diminishing returns curve

UpgradeApprox. accuracy gain (flick)Approx. cost$/percent gain
60 → 144 Hz10 to 20%$130 to $250~$15-20 / percent
144 → 240 Hz3 to 7%$120 to $300~$40-60 / percent
240 → 360 Hz1 to 3%$200 to $400~$100-200 / percent
360 → 480 Hz0.5 to 1.5%$300 to $700~$300-700 / percent

5. Other variables that compete with refresh rate

6. Realistic case studies

Player A: Bronze on 60 Hz

Largest single upgrade is the monitor. 60 → 240 Hz on a competent IPS panel will produce visible aim improvement with weeks of practice. Refresh rate alone moves them up.

Player B: Plat on 144 Hz with stock setup

Diminishing returns. The next biggest gains come from NVIDIA Reflex, lower latency mouse pad surface, and a 240 Hz upgrade with low pixel response — together, not 360 Hz alone.

Player C: Diamond on 240 Hz IPS, NVIDIA Reflex on, premium mouse

360 Hz upgrade is real but marginal. An OLED upgrade at 240 Hz might out-perform a 360 Hz IPS upgrade due to pixel response. Practice volume usually beats hardware here.

7. Buying recommendation by goal

8. Refresh rate inside aim training routines

If you are practising on the FPSTrain browser trainer or Kovaak's, your monitor refresh rate is the bottleneck most of the time because the trainer runs at extreme frame rates. The same five-block warmup outlined in the 15-minute pro warmup works on 60 Hz to 480 Hz; you simply have a lower performance ceiling at lower refresh.

10. Myths to retire

"You can see 1000 Hz." No. Edge-case studies show resolution above 200 Hz; 1000 Hz is below conscious perception in normal conditions but still useful for latency.

"360 Hz turns me into a pro." Skill is not refresh-rate gated. Refresh rate is a multiplier on existing skill; it cannot create skill that is not there.

"NVIDIA Reflex is marketing only." Reflex measurably reduces latency by reducing render queue depth. It is one of the highest-leverage free upgrades.

"If 60 Hz feels fine, refresh upgrades are unnecessary." Subjective comfort at 60 Hz does not measure the actual improvement available; A/B testing routinely shows 60 Hz players improve immediately on 144 Hz.
