Lazy Chunks
by rizen
Lazy Chunks is a Fabric client-side optimization mod that spreads chunk loading work over several frames to reduce stutters.
What it does
When the frame rate falls below a configurable threshold, chunk loading slows down so the drop does not become a sudden freeze. Once the frame rate recovers, chunks load faster again to keep the world responsive. Each frame, the amount of chunk work allowed is capped according to the FPS reading taken at that moment.
Key features
Dynamic chunk throttling
Chunk processing is spread across multiple frames, scaled to the current FPS rather than a fixed rate.
Configurable FPS threshold
The frame rate level below which chunk loading is slowed is set in the mod's configuration.
Debug overlay
Pressing F3 shows real-time throttling statistics in the debug overlay.
