Zenless Zone Zero (ZZZ) 2.4 Bug & Fix Guide (2026): Voice‑overs, Performance & More

on

Is your Zenless Zone Zero experience marred by missing voice lines, lag issues, or crashes? You’re not alone. While Version 2.4 “On the Precipice of the Abyss” delivered exciting story content and new agents like Banyue and Dialyn, it also brought technical hurdles that lingered into early 2026. This guide breaks down what’s confirmed fixed, what’s still problematic, and what you can do right now to improve your game experience.

🔥 Section 1 — 2.4 Overview: What This Update Changed

Version 2.4 was a major expansion for ZZZ:

  • It added two S‑Rank agents, Dialyn and Banyue, each introducing new combat dynamics and team options.

  • New W‑Engines and Bangboo support units arrived.

  • Story progression continued with “On the Precipice of the Abyss.”

  • Compensation Polychromes were issued because of launch issues.

Alongside content, there were quality‑of‑life improvements and animation/UI fixes included in the initial 2.4 patch.

⚠️ Section 2 — Critical Ongoing Issues (Confirmed)

All Known Issues & Bugs in ZZZ 2.4 (On the Precipice of the Abyss)

1. Missing Voice‑overs in Main Story (English/Japanese/Korean)

Status: Still partially present as of early 2026 — multiple sources confirmed that English, Japanese, and Korean voice files were missing at launch and are promised for future updates.

Despite compensation given in‑game for this issue, developers have not fully restored all affected voice lines yet. The Chinese voice track is generally unaffected.

Practical Tips:

  • Ensure subtitles are enabled.

  • Temporarily switch to Chinese VO for seamless audio.

  • Keep an eye out for future patch announcements for full restoration.

2. Performance Drops & FPS Stutters

Many players report frame dips and stutter during graphically demanding segments (e.g., big boss fights like Neo Golden Mecha). This aligns with community reports even beyond official patch notes.

Common Causes:

  • High particle effects + crowded UI.

  • Resource bottlenecks on mid‑range hardware.

What You Can Do:

  • Lower shadow quality, reflections, volumetric fog, and effects.

  • Consider capping FPS to reduce fluctuation.

  • Close background apps on PC/mobile to free CPU/RAM.

  • On consoles, switching to performance mode often helps.

Note: Players have been discussing persistent FPS hitches and lag even outside official fixes.

3. Loading Delays & Texture Pop‑In

Community threads highlight slow loading screens and visible pop‑in of assets, especially around newer areas. These don’t seem to be fully fixed by 2.4 alone and may linger until future revisions.

🛠️ Section 3 — Resolved 2.4 Issues (Officially Patched)

Here are problems officially fixed in the Version 2.4 patch:

  • Animation glitches for certain characters.

  • UI sorting errors and stuck indicators.

  • Hollow Zero kill count bug.

  • Some incorrect interface icons.

These fixes should be live on all platforms if your game is updated and restarted.

🧠 Section 4 — Game Optimization Checklist (2026 Tips)

Here’s a quick, practical step‑by‑step optimization list to improve stability and visuals across devices.

Graphics Settings (PC/Console):

  • ✨ Shadows: Low — big FPS gains

  • 💧 Volumetric Fog: Medium/Low — smoother scenes

  • 🎇 Reflections: Disabled or Medium — steadier frames

  • 📉 Effects & Bloom: Disabled — reduces stuttering

  • 📊 Resolution Scale: Lower if needed for performance

Connection & Network:

  • Use a wired internet connection if possible.

  • Close downloads or streaming during play.

  • Avoid switching servers mid‑session.

Launch & Stability:

  • Fully restart the game after long sessions.

  • Make sure your launcher and device drivers are up to date.

⭐ Section 5 — Combat & Meta: Building Banyue (2026)

Even with technical issues, 2.4’s combat meta matured through community experimentation. Here’s a 2026‑aligned snapshot:

Recommended Focus for Banyue

  • Skill priority: EX Special → Core Skill → Basic Attack

  • Best W‑Engine: Wrathful Vajra

  • Recommended Drive Discs: 4‑piece Yunkui Tales + 2‑piece Branch & Blade Song

🛎️ Section 6 — How to Report New Bugs (Best Practices)

To help the devs fix issues faster:

  • Use in‑game feedback tools and official Discord.

  • Provide OS, device model, reproduction steps, and screenshots/video.

  • Report consistently — developers monitor threads for repeatable bugs.

🧭 Section 7 — What’s Next: Version 2.6 (Feb 6, 2026)

  • New characters and factions

  • Expanded story content

  • More quality‑of‑life improvements

This update offers hope that remaining glitches — including voice‑over gaps and some performance kinks — may be further refined.
