No redstone lag

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

• Rebuild throttle (default 200 ms): a chunk section that was just re-meshed waits a moment before it is rebuilt again. Busy piston/redstone sections drop from 20+ rebuilds per second to a handful – the farm keeps running at full speed, it just looks a little choppier. Blocks you place or break yourself still update instantly. Adjustable: off / 50 / 100 / 200 / 350 / 500 ms.
• Item & XP render distance (default 24 blocks): farms spit out tons of drops; items and XP orbs further away than this simply aren’t drawn. Adjustable: off / 8 – 64 blocks.
• Sound limiter: identical redstone sounds (pistons, dispensers, hoppers, …) are capped to 3 per tick instead of hundreds.

✨ Particles

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

• Redstone dust puffs (dust, torches, repeaters, …)
• Dispenser / dropper smoke
• Note block notes
• Sculk sensor vibrations

🔇 Sounds

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

• Piston extend/retract
• Dispenser / dropper clicks
• Note blocks

🖥️ 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.

✅ Good to know

• 100% client-side. Works in singleplayer and on any server (including vanilla servers) – nothing is sent or changed server-side, so it’s safe for survival servers.
• No gameplay changes. Farm rates, timings and mechanics stay exactly vanilla; only rendering, particles and sounds are affected.
• Plays nice with performance mods. Hooks were chosen to sit alongside Sodium & friends (piston, particle and sound features use the shared code paths both renderers call).
• Requires: Fabric Loader + Fabric API. Optional: Mod Menu (config button).

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.

• Kolben ohne Animation: Bewegte Kolben (und alle geschobenen Blöcke) werden nicht mehr jeden Frame neu gerendert – sie springen direkt zwischen ein- und ausgefahren. Größter Gewinn in Piston-Farmen.
• Chunk-Updates überspringen: Reine Signal-Änderungen (Staub-Power, Repeater, Comparator, Observer, Target, Sculk, Lampe, Kupferbirne) lösen kein Re-Meshing der Chunk-Section mehr aus. Der Kompromiss ist rein optisch – die Schaltung funktioniert unverändert.
• FPS-Booster: Rebuild-Drossel (Chunk-Sections werden max. ~5×/s neu gebaut), Item/XP-Sichtweite (Standard 24 Blöcke) und Sound-Limiter (max. 3 gleiche Redstone-Sounds pro Tick).
• Partikel-Filter: Redstone-Staub, Werfer/Spender-Rauch, Notenblock-Noten, Sculk-Vibrationen.
• Sound-Filter: Kolben, Werfer/Spender und Notenblöcke stummschalten (standardmäßig aus).

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