No Redstone Lag Mod (1.21.11) – Run Giant Redstone Farms Without Frame Rate

No Redstone Lag Mod optimizes the hidden rendering cost of big redstone farms and machines. Pistons snap without animations, chunk rebuilds slow down, and noisy particles and sounds can be filtered out. This mod works only on your own screen, so it is safe on any server. You choose which parts to speed up, live in the game.

Features:

• No Piston Animations: Pistons snap straight between retracted and extended. Moving piston heads and the blocks they push are no longer redrawn every frame. Tree farms, sugarcane farms and flying machines still work the same.
• Skips Useless Chunk Rebuilds: Changes that only affect signal state (power, lit, powered, locked, sculk phase) no longer force the game to rebuild the whole chunk section. The circuit shape did not change, so the rebuild is not needed.
• Rebuild Throttle: A chunk section that was just rebuilt waits a moment before it can be rebuilt again. The default is 200 ms. Busy sections drop from 20+ rebuilds per second to just a few. Options are off, 50, 100, 200, 350 and 500 ms.
• Item and XP Render Distance: Items and XP orbs farther away than the set distance are not drawn. The default is 24 blocks. You can set it to off or anything from 8 to 64 blocks.
• Sound Limiter: Identical redstone sounds from pistons, dispensers, hoppers and more are capped at 3 per tick instead of hundreds.
• Live Settings Screen: A vanilla-style GUI has a master switch and one toggle per part. Changes apply right away with no restart. English and German translations are included.
• Blocks you place or break yourself still update instantly, even with the throttle on.
• Works in singleplayer and on any server, including vanilla servers. Nothing is sent to or changed on the server.
• Farm rates, timings and mechanics stay exactly like vanilla. Only rendering, particles and sounds change.
• Plays nicely next to performance mods like Sodium.
• A skipped part may keep its old texture or tint until its chunk section is rebuilt for another reason. This is only a visual trade-off. Hitboxes and circuits are not touched.

Chunk Update Toggles:

• Redstone dust: on by default. The dust tint may update late, but the circuit still works.
• Repeater: on by default.
• Comparator: on by default.
• Redstone torch: on by default. Light updates still refresh it.
• Observer: on by default.
• Target block: on by default.
• Sculk sensor: on by default.
• Redstone lamp: off by default, because it gives off light and looks matter more.
• Copper bulb: off by default. Only available in 1.21+ and 26.x.

Particle Filters:

• Hide redstone dust puffs from dust, torches, repeaters and more.
• Hide dispenser and dropper smoke.
• Hide note block notes.
• Hide sculk sensor vibrations.

Sound Mutes:

• Mute piston extend and retract sounds.
• Mute dispenser and dropper clicks.
• Mute note blocks.
• All mutes are off by default. Turn on only what annoys you.

How to Use:

1. Press B to open the settings screen. You can change this key in Controls. You can also open it from Mod Menu.
2. Use the master switch to turn the whole mod on or off in one click.
3. Pick a tab: General (includes the FPS boosters), Particles, Sounds or Chunk Updates.
4. Toggle the parts you want. Changes apply instantly.
