SmoothCore is a client-side performance mod for Minecraft focused on smoother frame times, better 1% lows, reduced micro-stutter, and more stable gameplay during heavy scenes.
SmoothCore is not built only to increase the maximum FPS number. Its main goal is to make the game feel smoother by reducing, reusing, limiting, delaying, or skipping unnecessary visual work when Minecraft becomes demanding.
It helps during exploration, entity-heavy areas, farms, particle-heavy scenes, chunk activity, and modded gameplay.
SmoothCore monitors frame time and reacts when the game starts struggling.
It can detect pressure caused by:
Based on the detected bottleneck, SmoothCore adjusts its optimization level automatically.
SmoothCore reduces expensive entity rendering work while keeping nearby and important entities safe.
Includes:
Protected entities include players, the camera entity, nearby entities, and gameplay-relevant entities.
SmoothCore can optimize distant or static block entities by reusing cached render states and safely skipping low-priority work.
Includes:
This helps in areas with many signs, containers, or other block entities.
SmoothCore can limit excessive particle creation and reduce update work from low-priority particles.
Important particles receive higher priority, while distant or less important particles can be reduced more aggressively during performance drops.
On vanilla rendering, SmoothCore can spread chunk rebuild and upload pressure across multiple frames to reduce spikes.
When Sodium or Nvidium is detected, overlapping vanilla chunk hooks are automatically disabled to avoid duplicate work.
When GPU pressure rises, SmoothCore can reduce distant or low-priority visual work first.
This helps keep frame times more stable without changing gameplay mechanics.
SmoothCore protects its automatic calibration from large temporary spikes caused by:
These spikes are ignored so they do not incorrectly affect long-term tuning.
SmoothCore can skip very distant or excessive duplicate sounds.
It uses fail-safe behavior so unknown sounds or modded sounds are passed back to vanilla instead of breaking.
Repeated GUI text work can be cached to reduce small but frequent interface costs.
SmoothCore includes simple presets:
SmoothCore includes a performance dashboard showing what the mod is actually doing.
Stats include:
This makes it easier to verify that SmoothCore systems are active and helping in your current world.
Use:
/smoothcore benchmark
This runs a temporary A/B comparison inside the same game session.
It compares:
Metrics include:
The benchmark helps estimate how much SmoothCore is affecting performance on your machine, in your current world, and with your modpack.
SmoothCore is designed to coexist with other performance and utility mods.
Supported compatibility handling includes:
When another mod already handles the same optimization area, SmoothCore can automatically disable overlapping modules to avoid duplicate work or conflicts.
Use:
/smoothcore compat
This shows detected mods, active integrations, and SmoothCore modules changed by compatibility rules.
SmoothCore only needs to be installed on the client.
Servers do not need SmoothCore installed.
SmoothCore v1.0.0 is the first stable release, focused on frame-time stability, safe compatibility, smarter rendering optimization, and reduced micro-stutter without changing gameplay.
