Understanding Minecraft’s Default Tick Speed
The normal tick speed in Minecraft is 20 ticks per second, which means the game processes updates every 0.05 seconds (50 milliseconds). This is the standard rate at which Minecraft’s game loop runs, handling everything from player movement to block updates.
Game Ticks vs Random Tick Speed
It’s important to distinguish between two different types of ticks in Minecraft:
- Game ticks: Always run at 20 per second and control core game mechanics
- Random tick speed: Controls how often random block updates occur (like crop growth)
The default random tick speed is set to 3, which means each chunk section has 3 random block updates per game tick. This affects things like grass spreading, leaf decay, crop growth, and fire spread.
What Happens During Each Tick
Every game tick, Minecraft processes numerous operations including:
- Entity movement and physics calculations
- Redstone circuit updates
- Mob AI decisions and pathfinding
- Block state changes
- Weather and day/night cycle progression
Performance Impact
When your server or game can’t maintain the full 20 ticks per second, you’ll experience lag. Server administrators often monitor TPS (ticks per second) to gauge performance. A healthy server should consistently run at 20 TPS.
Understanding tick mechanics helps you optimize your Minecraft experience and troubleshoot performance issues. For players looking to dive deeper into Minecraft’s technical aspects, exploring different game modes and mechanics can enhance your understanding of how the game operates.
TL;DR
Minecraft runs at 20 ticks per second (50ms intervals) for game mechanics, with a default random tick speed of 3 for block updates like crop growth.
