Performance Guide

Running a modded Minecraft like Create Chronicles can be demanding. This guide will help you get the best performance by adjusting RAM, CPU usage, and key config settings.

How Minecraft Uses System Resources​

  • RAM (Memory): Needed to load mods, world data, and keep entities active. Too little = lag, crashes. Too much = garbage collection issues.
  • CPU (Processor): Minecraft is mostly single-threaded but uses more threads for mods, chunk loading, and world gen.
  • Storage: SSDs dramatically improve world loading and chunk saving speed.

Using a Reliable Launcher​

To ensure the modpack runs smoothly and updates properly, we strongly recommend using one of the following trusted launchers:

  • ✅ CurseForge Launcher — Official curseforge launcher with mod support and easy updates.
  • ✅ ATLauncher — Lightweight and stable alternative.

❌ Avoid cracked or unofficial launchers. These often cause unexpected issues, and we cannot provide support for them.

RAM Allocation​

Recommended: 8 GB of RAM

Too little RAM = crashes
Too much RAM = laggy garbage collection (GC) and lagg spikes in game.

note

💡 Giving Minecraft too much RAM is like giving your browser 64 tabs — it’ll eat them all and ask for more 😅

How to Change RAM on:​

CurseForge Launcher:​

  1. Go to Settings > Minecraft Alt text Alt text
  2. Scroll to Allocated Memory
  3. Set it to 8192 MB (8 GB)

ATLauncher:​

Adjust the maximum memory (Xmx) and minimum memory (Xms) in the Java settings.

-Xmx8G -Xms4G

Need smoother performance or fewer stutters?
Try these JVM arguments to optimize memory usage and garbage collection.

-XX:+UnlockExperimentalVMOptions 
-XX:+UseG1GC 
-XX:G1NewSizePercent=20 
-XX:G1ReservePercent=20 
-XX:MaxGCPauseMillis=50 
-XX:G1HeapRegionSize=32M

Update GPU Drivers​

Keeping your drivers up to date = better FPS.

Check your GPU:​

  1. Open Task Manager → Performance tab
  2. Click GPU 0 to see your GPU model

Video Settings​

  • Turn off FPS counter and avoid using F3 — it lowers performance.
  • Disable VSync — use the FPS cap slider instead.
  • Lower game resolution (great for high-res displays like Retina).
  • Reduce Render Distance to 6–8 chunks.
  • Lower Simulation Distance (can affect farms).
  • Set Particles to Minimal or Decreased.
  • Lower Entity Distance to ~75%.

CPU Tips​

Minecraft loves clock speed, not core count.

  • Ideal: CPU with 3.5 GHz or higher
  • Minecraft uses:
    • 1 thread for the main game loop
    • Extra threads for world gen, IO, and some mods (like Create, Distant Horizons, etc.)
warning

💡 Avoid shared hosting with low GHz CPUs. Use a dedicated server or premium host (like Bisect Hosting).

Last Tips​

  • Install Minecraft on an SSD — much faster chunk loading and smoother gameplay.
  • Enable XMP in BIOS — ensures your RAM runs at full speed.
  • Set Java priority to "Above Normal" in Task Manager after launching Minecraft.
  • Force Minecraft to use your discrete GPU (check with F3):
    • Go to Windows Settings > Display > Graphics Settings
    • Add javaw.exe and set it to High Performance
  • Close background apps — browsers, Discord, and launchers eat CPU, RAM, and disk speed.
