Step 1 of 4
How are you playing right now?
Handheld is the lowest-latency baseline. Everything else adds a display and audio chain that can lag.
Why input lag matters in rhythm games
Rhythm Heaven Groove grades every input against a precise timing window. A display that adds 60 ms of latency means the visual beat you see is already 60 ms behind reality — so your reflexes are calibrated against a stale signal. Even the in-game offset tool can only compensate for fixed delays; Bluetooth audio drift is variable and cannot be calibrated out.
The wizard above diagnoses the three main sources of lag — display processing, audio path, and controller type — and gives you the highest-priority fixes first.
Quick reference
- Handheld mode — lowest latency baseline. Always calibrate here first.
- Game Mode / Low Latency Mode — biggest single docked fix. Cuts TV lag from 50–150 ms to 5–20 ms.
- Wired audio — essential for rhythm play. Bluetooth headphones add 40–200 ms of variable delay.
- In-game recalibration — required every time you change display or audio setup.
Input lag FAQ
Why does rhythm game timing feel wrong on my TV?
TV displays add latency between the game signal and what you see — often 20–80 ms in standard mode. Audio can add even more if routed through Bluetooth or a soundbar. Together these make inputs feel early or late.
What is Game Mode on a TV?
Game Mode bypasses most post-processing pipelines in your TV, cutting display latency from 50–150 ms down to 5–20 ms. Look for it in your TV's picture settings — sometimes labelled "Low Latency" or "Instant Game Response".
Does wireless controller input add lag?
Nintendo's wireless controllers (Pro Controller, Joy-Con) add roughly 4–8 ms, which is below most players' detection threshold. Controller input is rarely the bottleneck — display and audio are almost always the culprit.
Will the in-game calibration fix everything?
The in-game offset calibration compensates for a fixed delay — but it cannot fix variable Bluetooth audio lag, which fluctuates. Fix your setup first, then calibrate.
