FPSCraft for More FPS

FPSCraft — The Ultimate Performance-First Vanilla+ Experience

📌 Overview

FPSCraft is a carefully engineered Minecraft Forge 1.20.1 optimization modpack designed to deliver a significantly smoother and more responsive vanilla experience while keeping gameplay almost completely unchanged.

Instead of combining dozens of random "FPS Boost" mods that often overlap, conflict with each other, or create instability, FPSCraft focuses on a carefully tested collection of modern optimization technologies. Every included mod has been selected because it provides a measurable benefit while remaining fully compatible with the rest of the pack.

The goal is simple: reduce unnecessary CPU workload, lower memory usage, improve rendering efficiency, minimize stuttering, and create smoother frame pacing without sacrificing Minecraft's original look and feel.

Whether you're playing on an older laptop struggling to reach playable frame rates or on a high-end gaming PC capable of rendering hundreds of frames per second, FPSCraft is built to make the game feel smoother, more consistent, and more enjoyable.

🚀 What FPSCraft Optimizes

FPSCraft improves performance on multiple levels instead of relying on a single optimization mod.

Modern Rendering Pipeline

Rendering is handled by modern optimization technologies built around the Embeddium ecosystem.

The rendering engine performs fewer unnecessary calculations, reduces rendering overhead, improves chunk rendering efficiency, and optimizes visibility checks. This allows your graphics card to spend more time rendering what is actually visible instead of processing work that provides no visual benefit.

---

Memory Usage

Minecraft's memory consumption has been reduced using carefully configured optimization mods such as FerriteCore and ModernFix.

Various configuration improvements reduce unnecessary memory allocations, decrease startup memory usage, and improve long-term stability during extended play sessions.

The result is lower RAM usage, fewer memory spikes, and smoother gameplay over time.

---

Garbage Collection Improvements

Minecraft runs on Java, which periodically performs Garbage Collection (GC) to free unused memory.

Improper JVM settings can cause noticeable lag spikes while Java performs this cleanup.

FPSCraft includes recommended JVM arguments that optimize the G1 Garbage Collector for smoother frame pacing and more predictable memory management.

While JVM arguments cannot magically increase FPS, they can reduce noticeable pauses and improve gameplay consistency on many systems.

---

World Performance

FPSCraft automatically applies carefully selected gamerules to newly created worlds using Paxi.

These settings are chosen to reduce unnecessary server-side calculations while preserving normal survival gameplay.

Players don't need to manually enter commands every time they create a new world—the optimization settings are applied automatically.

---

Rendering & Visibility Optimizations

Several rendering optimizations reduce the amount of unnecessary work performed every frame.

Objects hidden behind terrain or outside the player's visible area can be skipped by supported optimization mods, reducing GPU workload and improving overall rendering efficiency.

---

Carefully Selected Optimization Mods

Every optimization mod included in FPSCraft has been tested together to avoid overlapping functionality whenever possible.

Rather than chasing the highest possible number of optimization mods, FPSCraft focuses on compatibility, stability, and real-world performance.

The objective is consistent gameplay—not simply installing as many "performance" mods as possible.

💻 System Recommendations

Minecraft Version

Forge 1.20.1

Java Version

Java 17 (64-bit)

Minimum RAM

4 GB allocated to Minecraft

Recommended for lightweight gameplay and lower render distances.

Recommended RAM

6 GB allocated to Minecraft

Provides the best balance between memory usage, chunk loading performance, and overall stability for the complete FPSCraft experience.

Best RAM

10 GB allocated to Minecraft

If your system supports it, allocating 10 GB of RAM can help this modpack run more smoothly by reducing lag spikes, improving chunk loading performance, and providing additional memory for mods and background processes. However, only allocate as much RAM as your system can comfortably handle.

☕ Recommended JVM Arguments

For the best experience, allocate 6 GB of RAM and use the following JVM arguments:

-Xms6G
-Xmx6G
-XX:+UseG1GC
-XX:+ParallelRefProcEnabled
-XX:MaxGCPauseMillis=100
-XX:+UnlockExperimentalVMOptions
-XX:+DisableExplicitGC
-XX:+AlwaysPreTouch
-XX:G1NewSizePercent=30
-XX:G1MaxNewSizePercent=40
-XX:G1HeapRegionSize=16M
-XX:G1ReservePercent=20
-XX:G1MixedGCCountTarget=4
-XX:InitiatingHeapOccupancyPercent=15
-XX:G1MixedGCLiveThresholdPercent=90
-XX:G1RSetUpdatingPauseTimePercent=5
-XX:SurvivorRatio=32
-XX:+PerfDisableSharedMem
-XX:MaxTenuringThreshold=1
