Sync Fix Core Mod loads as a GameLibrary and injects ASM patches before the game starts, enabling SyncFix to measure tick durations and regulate scheduled ticks under overload. While Sync Fix Mod handles the optimization logic, Sync Fix Core provides the hooks and instrumentation that make it possible.
Features:
- SyncFix Core plugs into Minecraft’s startup process so it can prepare everything before you even join a world.
- It keeps track of how long each server tick takes, so Sync Fix knows when the server is slowing down.
- When the server is overloaded, it can trim or adjust background tasks (like block updates) so the game doesn’t fall behind.
- It sets a flag so the main Sync Fix mod knows the patches are working.
- You don’t have to configure anything, it runs automatically once installed.
