## 🧠 **Recommended JVM Arguments**
These JVM args maximize performance and stability for most systems (modern CPUs, 8–16 GB RAM total).
Paste them in your launcher’s *“Java Arguments”* or *“JVM Settings”* field:
```-Xms4G -Xmx8G -XX:+UseG1GC -XX:+ParallelRefProcEnabled -XX:MaxGCPauseMillis=100 -XX:+UnlockExperimentalVMOptions -XX:+DisableExplicitGC -XX:+AlwaysPreTouch -XX:G1NewSizePercent=30 -XX:G1MaxNewSizePercent=40 -XX:G1HeapRegionSize=8M -XX:G1ReservePercent=20 -XX:G1HeapWastePercent=5 -XX:G1MixedGCCountTarget=4 -XX:InitiatingHeapOccupancyPercent=15 -XX:G1MixedGCLiveThresholdPercent=90 -XX:G1RSetUpdatingPauseTimePercent=5 -XX:SurvivorRatio=32 -XX:+PerfDisableSharedMem -XX:MaxTenuringThreshold=1 -Dfml.ignorePatchDiscrepancies=true -Dfml.ignoreInvalidMinecraftCertificates=true```

## 📝 **Tips:**
- Adjust `-Xmx` (max memory) to match your available RAM — e.g., `6G`, `8G`, or `10G`.
- Keep `-Xms` (minimum) lower than or equal to half of your max allocation.
- Avoid running background-heavy programs while Minecraft is open for the best results.

## ⚡ **Optional Tweaks**
- 🧹 **LazyDFU Alternative:** Not needed — handled by **ModernFix** and similar mods.
- 🔄 **Thread Tweaks:** Improves multithreading for chunk loading & world generation.
- 🖥️ **VBOs + VSync:** Enable in settings for smoother frame pacing if screen tearing occurs.
- 🔧 **Resource Packs:** Use low-resolution packs (≤128x) for best memory efficiency.
