Mod StutterFix

StutterFix, smoother chunk generation

StutterFix is a Fabric mod for Minecraft Java Edition designed to reduce short freezes and frame stutters while unexplored chunks are generated. Rather than changing terrain generation itself, it adjusts how the game’s worker, rendering, and integrated server threads use processor time.

Its options let players tune worker thread count, priority levels, rendering thread priority, and, where available, the removal of Thread.yield(). Lower worker usage can improve responsiveness, although generation may take longer. The mod is mainly useful in singleplayer, since chunk generation in multiplayer is handled by the server. At BoxToPlay, we recommend it for a more consistent exploration experience on supported Fabric setups.
