The 30-second TL;DR

Do this in order: fix screen → fix audio → then calibrate in-game.

  1. Turn on Game Mode on your TV/monitor (reduces display lag).
  2. Avoid Bluetooth audio (wired audio is best for rhythm accuracy).
  3. Use the game’s Timing Adjustment after your setup is stable.
Common beginner trap: If you calibrate first while your TV/audio is laggy, you’ll end up “tuning around” a moving target. Fix the chain first.

Why it feels “off”

1) Display lag (what you SEE is late)

Your screen may process the image before showing it. TVs are the most common source of extra lag.

  • Motion smoothing / “AI picture” features usually add delay
  • Game Mode is designed to reduce that processing

2) Audio delay (what you HEAR is late)

Bluetooth audio often adds noticeable delay. Rhythm games feel “floaty” even if your hits are correct.

  • Wired audio is the most consistent
  • Long audio delay makes timing adjustment harder
Good news: Most setups improve dramatically once you enable Game Mode and switch to wired audio.

Step 1 — Fix your screen

If you play on a TV

  • Enable Game Mode (sometimes called Gaming / Low Latency / ALLM).
  • Turn off “pretty” features that add lag:
    • Motion smoothing / TruMotion / MEMC
    • Noise reduction
    • Film mode / de-judder
    • AI picture processing

Goal: make the TV as “dumb and fast” as possible.

If you play on a monitor

  • Use the monitor’s fastest preset (often Fast / Gaming / Low Input Lag).
  • Avoid extra converters/splitters if you can.

Step 2 — Fix your audio

Best options (ranked):

  1. Wired headphones (most consistent)
  2. Wired speakers / display audio-out
  3. Bluetooth only if you know your chain is low-latency
Beginner tip: If you’re chasing the beat and it never feels stable, try wired audio first — it’s the fastest “big win”.

Step 3 — Calibrate in-game (do this last)

Once your screen and audio are stable, use the game’s Timing Adjustment (calibration).

  1. Go to Settings → Timing Adjustment (wording varies by platform/version).
  2. Start with the game’s guided tool (if available).
  3. Then fine-tune until “Perfect” feels natural on steady patterns.
  4. Test with a consistent song you can repeat easily (not your hardest chart).
What “good” looks like: Judgement feels consistent. You’re not constantly “late” or “early” across different songs.

Quick diagnosis

My hits feel late, but the audio seems fine
That’s often display lag. Re-check TV Game Mode, and disable motion smoothing / AI picture processing.
The beat sounds behind (I feel like I’m chasing the music)
That’s often audio delay. Try wired headphones/speakers and avoid Bluetooth for calibration.
It feels different day to day
You may be changing something in the chain (TV mode, headphones, dock/receiver, different display). Keep the setup consistent before calibrating.

Beginner FAQ

Should I calibrate first?
Usually no. Fix screen + audio first, then calibrate. Otherwise you’re compensating for lag that can change later.
What’s a “good” latency number?
There isn’t one perfect number, but rhythm games benefit from the lowest lag you can get. Start by enabling Game Mode and using wired audio — those are the biggest wins.
Why does Bluetooth feel so bad?
Bluetooth audio adds encoding/decoding and buffering delay. Even if it sounds fine, the timing can be late enough to break rhythm accuracy.
You’re not “bad” — your setup is lying to you.
Once latency is under control, improvement feels immediate: hits “snap” into place and consistency returns.

Still stuck? We’ve got you.

Email us at support@rythmagica.net. Tell us your platform (Switch/PS4/PC), your screen model, and whether you’re using Bluetooth audio.

  • Best: a short video showing the game screen + your audio setup
  • Also helpful: what you changed (Game Mode on/off, wired vs Bluetooth, etc.)

We’ll suggest the fastest path to a solid baseline.
