⚠️ Warning ⚠️

This modpack does not try to be Vanilla or Vanilla+ (e.g. do not expect mob farms to work as intended).

This modpack is still in Beta, some mods are still missing.

Another Opionated Minecraft Modpack. Based on Additive.

• This modpack was created for myself.

What does this modpack try to accomplish?

• Good performance.
• Latest versions and features.
• Better Minecraft experience (in my opinion).

Recommended requirements

• Prism Launcher.
• Adoptium JDK/JRE (Java 25, JDK is still preferred over JRE).
• At least 4GB of RAM for the game.
• OpenCL capable GPU (if you plan to use C2ME OpenCL Acceleration Module).
• For Minecraft 26.2 OpenGL is still more recommended than Vulkan.

Recommended JVM arguments (Java 25)

-XX:+UseZGC -XX:+UseCompactObjectHeaders -XX:+UseStringDeduplication -XX:+AlwaysPreTouch -XX:+PerfDisableSharedMem -XX:-ZUncommit

add -XX:+UseTransparentHugePages if you use Linux (madvise).

add -XX:+UseLargePages if you use Windows (requires additional configuration).

-Xms and -Xmx should use the same size of ram for the best performance (e.g. -Xms 4096 -Xmx 4096).

Alternative JVM arguments:

-XX:+UseShenandoahGC -XX:ShenandoahGCMode=generational -XX:+UseCompactObjectHeaders -XX:+UseStringDeduplication -XX:+AlwaysPreTouch -XX:+PerfDisableSharedMem
