About this Mod

Smart Optimization

Smart Optimization is an adaptive performance optimization mod for Minecraft that automatically adjusts your graphics settings based on your current FPS.

The mod continuously monitors performance and dynamically applies or restores graphical settings depending on whether your game is running below or above your configured FPS thresholds.

This allows you to keep high-quality visuals most of the time while still ensuring smooth gameplay during heavy performance drops.

⚠️ This mod is still in active development. Features may change, and new optimization options will be added over time.


Important stuff

The update time is the time it takes to change the settings again. If you're not sure what value is the best for your device, then this section would be helpful.

If you have a low-end PC or laptop and always want to play with a lot of FPS, I recommend setting the update time to a lower value like 30 (seconds)

If you want stable FPS, even if you have a good PC or laptop, I will recommend setting the update time to a higher value like 300 (seconds / 5 minutes).

**You can edit the update time in the chat with this command:

/smartopt updatetime **

Note: The lowest value you can enter is 20 (seconds). The highest value you can enter is 600 (seconds / 10 minutes)


How it works

Smart Optimization tracks your average FPS over time.

  • If FPS drops below the low threshold, the mod gradually reduces performance-heavy settings.
  • If FPS rises above the high threshold, the mod restores your original settings step by step.

Before making any changes, Smart Optimization saves your original configuration so everything can be restored exactly as it was.

Optimizations are applied gradually in a controlled order to avoid sudden visual changes.


Optimizations include

Depending on configuration, Smart Optimization can adjust the following:

  • Entity render distance
  • Entity shadows
  • Particle effects
  • Cloud rendering
  • Simulation distance
  • Render distance

Each category can be individually enabled or disabled.


Commands

FPS control

Set the FPS threshold for when optimization starts:

/smartopt low <fps>

Set the FPS threshold for when settings are restored:

/smartopt high <fps>

Set how often FPS is checked:

/smartopt updatetime <seconds>


Configuration system

Enable or disable specific optimizations:

/smartopt configure <setting> <true/false>

Available settings:

  • entitydistance
  • entityshadows
  • particles
  • clouds
  • simulationdistance
  • renderdistance

Example:

/smartopt configure particles false

This prevents Smart Optimization from modifying particle settings.

Frequently Asked Questions

Does Smart Optimization need to be installed on the Minecraft server?

No. Modrinth marks Smart Optimization as unsupported on the server side. Install it only in your local Minecraft mods folder. Your server can remain unchanged unless the mod page lists an additional dependency.

Which version and loader does Smart Optimization require?

Use a file for fabric and your exact Minecraft version. Supported versions include 1.21.11. Files for different loaders are not interchangeable.

Smart Optimization is not working – what should I check?

First check the Minecraft version, loader version and required dependencies. Put the .jar file in your local .minecraft/mods folder and remove older duplicates. Because this mod is client-side, adding server RAM will not fix it.
