ZERQIUM

Client-side performance mod that measures, diagnoses, and safely optimizes your game — real bottleneck detection, stability-first metrics (1% lows, P99), and automatic fallback if anything goes wrong. No telemetry, no cheats.v

About this project

What does ZERQIUM add?

ZERQIUM is a client-side performance and diagnostics mod that refuses to guess. Instead of blindly toggling optimizations and hoping for the best, ZERQIUM measures your game first, diagnoses the real bottleneck, and only then applies safe, validated, reversible optimizations — automatically rolling back the instant anything looks wrong. No telemetry. No server requirement. No cheats. Just a smarter way to make Minecraft run better.

"Fast, but not reckless. Adaptive, but not intrusive. Powerful, but measurable."

🚀 Why ZERQIUM?

Most performance mods chase one number: average FPS. ZERQIUM thinks that's the wrong metric.

A mod that boosts your average FPS by 8% while making your 1% lows worse isn't an optimization — it's a regression wearing a costume. ZERQIUM's internal philosophy ranks stability above raw numbers:

1% low → 0.1% low → P99/P99.9 → frametime stability → average FPS → max FPS

If an optimization can't prove it helps without hurting stability, it doesn't ship active by default — or it gets automatically suspended.

🔍 What's inside

🩺 ZQ Doctor — Diagnoses why you're lagging: CPU-bound? GPU-bound? GC pauses? Doctor gives you a confidence-rated answer instead of a shrug — and honestly says "inconclusive" rather than making things up.

📊 ZQ Pulse — A built-in frame-time profiler tracking FPS, median frametime, P95/P99/P99.9, and 1%/0.1% lows — the metrics that actually determine whether your game feels smooth, not just what the counter says.

🧬 ZQ Adaptive — Dynamically tunes render distance and quality settings based on real, sustained performance trends — and steps out of the way the moment you touch a setting yourself. It never fights you for control.

🗃️ Static Render Cache — Chests, shulker boxes, and other block entities that never actually change get cached instead of re-rendered every frame — using a strict "dynamic until proven static" state machine, so nothing ever gets stuck looking wrong.

🛡️ Fail-safe by design — A circuit-breaker architecture that suspends any optimization that starts misbehaving and falls straight back to vanilla rendering. If your last session crashed with experimental features on, ZERQIUM notices and disables them on the next boot.

🖥️ Live HUD & full config GUI — Compact or advanced overlay showing FPS, 1%/0.1% lows, P99, memory, and active modules in real time — no need to run a separate profiler.

⌨️ /zq command suite — Status, hardware info, diagnostics, benchmarking, module control — all local to your client, nothing ever touches the server.

🔒 Built on trust

  • 100% client-side — install it, join any vanilla server or modded, done.
  • Zero telemetry, zero network calls by default.
  • No account, no login, no cloud dependency.
  • Never forces garbage collection.
  • Zero permanent background threads when idle.
  • Not a cheat mod — no X-ray, reach, combat automation, or ESP. Ever.

🗺️ Roadmap (coming in future updates)

ZERQIUM is being built as a long-term platform, not a one-shot mod. Planned for future releases:

  • GPU Compute offloading (experimental, opt-in)
  • GPU-resident data management (Residency)
  • Expanded Static Render Cache coverage (signs, banners, bells, lecterns)
  • Section Mesh rendering backend
  • NeoForge & Forge ports

This release focuses on getting the measurement, diagnostics, and core caching foundation rock-solid before expanding scope — because a performance mod that isn't itself fast and stable defeats the purpose.

⚠️ A note on honesty

We'd rather under-promise than over-sell. ZERQIUM doesn't guarantee a fixed FPS gain — your results depend on your hardware, render distance, shaders, other mods, and what's actually bottlenecking your game. What we do promise: every optimization ZERQIUM ships is measured, validated, and reversible.
