TickTact is a performance mod for Minecraft servers and singleplayer that improves performance by keeping TPS stable and MSPT low, reducing lag without breaking gameplay.

▶️ Demo (High MSPT vs Low MSPT):

MSPT (milliseconds per tick) is how long one server tick takes. To keep 20 TPS, a tick must finish in under 50 ms.
When MSPT goes above 50 ms, you get lag: delays, slow mob AI, redstone feeling “late”, and rubber-banding.

TickTact reduces how much work the server does each tick without breaking gameplay. Near players, things update normally so everything feels smooth. Far from players, updates happen less often to save CPU. If the server starts struggling, TickTact automatically becomes more strict to prevent big spikes, but it never freezes things forever: throttled mobs, farms, and machines still progress over time.

Works with both entities (mobs, animals, etc.) and block entities (machines, hoppers, chests, farms, redstone, modded blocks).

Best for:
- Servers or modpacks with lots of machines, farms, and big bases
- Singleplayer too (it still runs an internal server)

Note

This is the first release. If you find any bugs or mod compatibility issues, please report it.

TickTact is a lightweight performance mod for servers and singleplayer.

It reduces lag caused by active things like mobs, spawners, and block entities (modded machines, hoppers, chests, redstone, and more).

⏱️ What is MSPT (and why it matters)

MSPT (Milliseconds Per Tick) is how long the game takes to process one tick (AI, redstone, machines, crops, etc.). To keep 20 TPS, the server must finish each tick in under 50 ms. If MSPT goes above 50 ms, you get lag: delays, slow mobs, and rubber-banding.

TickTact helps keep MSPT low by reducing unnecessary work each tick.

🧠 How it works

TickTact uses a dynamic tick budget for loaded areas

Near players: entities and block entities tick normally. Far from players: they tick less often (based on distance and current server load).

This saves CPU time and keeps busy worlds responsive.

✨ Key Features

Smart Ticking Entities and block entities tick slower when far from players. Dynamic Budgeting TickTact monitors MSPT and automatically reduces load when the server starts lagging. Fairness System Nothing is frozen forever. Throttled objects still tick regularly, so farms, crops, and machines keep working. Configurable Presets Choose Safe, Standard, or Aggressive, or tune budgets in the config. Safe by Design Runs on the main thread. No risky async tricks. Who is this for? Modpack creators: keep big packs playable in busy worlds. Server owners: reduce lag from farms, grinders, and mega-bases. Singleplayer: singleplayer runs an internal server too, so this can reduce CPU spikes and micro-stutters. Note

This is the first release. Please report issues on the tracker so i can improve the mod.
