1. SYSTEM REQUIREMENTS & ALLOCATION
To handle the vast dimensions and high-quality textures, you must manually allocate enough RAM to your Minecraft launcher:

Minimum: 6 GB RAM

Recommended: 8 GB - 10 GB RAM

Java Version: Ensure you are using Java 17 (for Minecraft 1.18+) or the version required by your specific game version.

How to allocate RAM: Go to your Launcher Settings -> Java Settings/Installations -> More Options -> JVM Arguments. Change to .-Xmx...G-Xmx8G

If you are not playing on CurseForge/Official Minecraft Launcher/Modrinth, then paste these Java arguments into the appropriate cell in the launcher:

-XX:+UseG1GC -XX:+UnlockExperimentalVMOptions -XX:+AlwaysPreTouch -XX:+ParallelRefProcEnabled -XX:+DisableExplicitGC -XX:MaxGCPauseMillis=50 -XX:G1NewSizePercent=40 -XX:G1MaxNewSizePercent=50 -XX:G1HeapRegionSize=16M -XX:G1ReservePercent=15 -XX:G1HeapWastePercent=5 -XX:G1MixedGCCountTarget=4 -XX:InitiatingHeapOccupancyPercent=20 -XX:G1MixedGCLiveThresholdPercent=90 -XX:G1RSetUpdatingPauseTimePercent=5 -XX:SurvivorRatio=32 -XX:MaxTenuringThreshold=1
