TickTact
by norevy
TickTact tunes how often a Forge server processes distant mobs and block entities, so the server can keep its tick time under 50 ms in busy worlds.
What it does
Each game tick, the server has to finish all of its work within 50 milliseconds to hold 20 ticks per second. TickTact reduces that work by updating entities and block entities near players on every tick, while distant ones are updated less often. The rate it uses depends on the distance to players and on the current server load, which keeps the tick budget within what the hardware can finish.
Load-based scaling is meant to keep worlds responsive when many redstone machines, crops and mobs are active at once. Without such control, the mean server time per tick (MSPT) climbs past 50 ms, and players notice lag, slowed mobs and rubber-banding. The demo compares a high MSPT run with a low MSPT run to show the difference. The mod runs on client and server, so both the server and every player need it, and it targets Forge only, across 7 release versions, 1.20 – 1.20.6, with 1.1 for 1.20.6 as the latest file. It is released under All rights reserved and is not open source.
Key features
Distance-based tick rates
Entities and block entities near players tick normally, while those far away are updated less often.
Dynamic tick budget
The budget for loaded areas is adjusted according to the current server load rather than fixed.
Lower MSPT
Reducing unnecessary work per tick aims to keep the mean time per tick low for busy servers.
Smoother mob movement
Keeping the tick budget under control reduces the slowed mobs and rubber-banding that come from lag.
Compatibility
Latest build for each game version and loader.
Only full game releases are shown. This mod publishes no snapshot builds.
Use cases
Busy multiplayer servers
Server owners running many redstone machines, farms or mobs can keep MSPT below the 50 ms limit.
Singleplayer worlds with heavy builds
Players with large automated builds in a singleplayer world can reduce the lag those builds cause.
Who it’s for: Server owners and players with heavily loaded Forge worlds, where many entities and block entities are active at once.

What the author says
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…
