| Metric | Eaglercraft (old JS heap) | Eaglercraft 1.12 (WASM GC) | |--------|---------------------------|-----------------------------| | GC pauses (avg) | 45–80 ms (every ~2 sec) | <5 ms (rare, ~every 15 sec) | | Chunk load stutter | Yes (15–30 ms freeze) | None (async & smooth) | | Memory after 1 hour | 1.2–1.8 GB | 450–600 MB | | Tab crash likelihood | Medium–High | Very Low |
The resulting WebAssembly module ( classes.wasm ) can then be loaded and executed by a modern browser. Because the browser now natively understands how to manage the garbage-collected memory of the Java program, the entire process runs more smoothly and efficiently.
To understand why Eaglercraft 1.12 WASM-GC is a breakthrough, it helps to understand how browser-based ports have evolved: eaglercraft 112 wasm gc
is an experimental, performance-optimized port of Minecraft 1.12.2 designed to run directly in a web browser using WebAssembly with Garbage Collection (WASM-GC) . Unlike previous versions that relied on JavaScript (TeaVM), this version uses WASM to provide a significant FPS boost and better resource management. Key Features and Developers
: Unlike JavaScript, which is interpreted line-by-line, WebAssembly runs as near-native machine code directly on your CPU and GPU. | Metric | Eaglercraft (old JS heap) | Eaglercraft 1
Eaglercraft 1.12 uses a with a WASM GC backend:
: Unlike some older versions, the 1.12.2 project (led largely by community developer PeytonPlayz585) includes robust singleplayer world support. Key Benefits of the WASM-GC Runtime Lower Input Latency Unlike previous versions that relied on JavaScript (TeaVM),
: Low-spec Chromebooks, office computers, and older laptops can handle the WASM-GC client effortlessly, provided hardware acceleration is enabled in the browser settings. How to Play and Deploy Eaglercraft 1.12 WASM-GC
