Description
LazyChunks
A Fabric client-side mod that reduces chunk loading stutters by dynamically spreading chunk processing across multiple frames based on your current FPS.
What It Does
LazyChunks monitors your real-time FPS and limits how much chunk work is processed each frame.
When FPS drops below a configurable threshold, chunk loading is slowed down instead of causing sudden frame drops. When FPS is high, chunks load faster to keep the world responsive.
This results in smoother gameplay, especially during fast movement, elytra flight, or exploration.
Configuration
Config file is created at .minecraft/config/lazy_chunks.json on first launch.
| Option | Default | Description |
|---|---|---|
| lazyChunkLoadingEnabled | true | Enable/disable the mod |
| targetFps | 60 | Baseline FPS for budget calculation |
| fpsThreshold | 80 | FPS above which throttling is disabled (vanilla behavior) |
| baseWeightPerFrame | 3.0 | Base amount of chunk work allowed per frame at target FPS |
| maxFrameTimePercent | 12.0 | Max percentage of frame time for chunk processing (1-20) |
| proactiveThrottling | true | Reduce budget when frame times are unstable |
| teleportProtection | true | Extra conservative throttling after teleports/dimension changes |
| minimumBudget | 3.0 | Minimum weight budget to prevent complete stalls |
