No Redstone Lag

Massive redstone builds, playable framerates. No Redstone Lag is a client-side Fabric mod that strips away the invisible rendering cost of big farms and contraptions – and lets you choose exactly which redstone components get optimized, live in-game.

Press B (rebindable) or open the mod via Mod Menu to toggle everything on the fly: a master switch for the whole mod, plus one toggle per component.

✨ What it does

🔧 Pistons: no more animations

The single biggest FPS killer in piston-heavy farms is the moving-piston animation: every moving piston head and every block it pushes is re-rendered from scratch every single frame. No Redstone Lag skips that entirely – pistons simply snap between retracted and extended. Your tree farms, sugarcane farms and flying machines keep working exactly the same; they just stop melting your GPU.

🧱 Chunk updates: skip pure signal changes

Every time redstone dust changes its power level, a repeater locks, an observer pulses or a target block lights up, vanilla re-meshes the whole 16×16×16 chunk section – even though the circuit's shape didn't change at all. In a busy circuit this happens hundreds of times per second.

No Redstone Lag detects changes that only affect the signal state (power, lit, powered, locked, sculk phase) and skips the re-mesh for them. Toggleable per component:

Component Default Note
Redstone dust ✅ on dust tint may update late – circuit still works
Repeater ✅ on
Comparator ✅ on
Redstone torch ✅ on light updates still refresh it
Observer ✅ on
Target block ✅ on
Sculk sensor ✅ on
Redstone lamp ⬜ off emits light, so visuals matter more
Copper bulb ⬜ off 1.21+ / 26.x only

The trade-off is purely visual: a skipped component may keep its old texture/tint until the chunk section is rebuilt for another reason. Gameplay, hitboxes and the circuit itself are untouched.

🚀 FPS boosters

✨ Particles

Hide the particle spam of big contraptions – each with its own toggle:

🔇 Sounds

Mute the noisiest farm components (off by default – turn on what annoys you):

🖥️ GUI

Everything lives in a clean vanilla-style screen with four tabs – General (incl. FPS boosters), Particles, Sounds, Chunk Updates – plus a master switch to turn the whole mod on or off in one click. Changes apply instantly, no restart needed. English and German translations included.

Riesige Redstone-Bauten, flüssige FPS. No Redstone Lag ist eine rein client-seitige Fabric-Mod, die die versteckten Rendering-Kosten großer Farmen entfernt – und dich im Spiel auswählen lässt, welche Redstone-Komponenten optimiert werden.

Mit B (umbelegbar) oder über Mod Menu öffnest du das GUI: Hauptschalter für die ganze Mod plus ein Schalter pro Komponente, sortiert in vier Tabs (Allgemein, Partikel, Sounds, Chunk-Updates). Änderungen wirken sofort.

Komplett client-seitig und damit auf jedem Server nutzbar; Farmraten und Mechaniken bleiben 1:1 Vanilla. Benötigt Fabric API, optional Mod Menu.
