To get started:
Because WASM-GC executes instructions so rapidly, unthrottled frame rates can occasionally choke the browser's primary event loop, resulting in strange mouse input lag. Enabling Vertical Sync locks frame generation cleanly to your monitor's refresh rate.
: The "GC" in WASM-GC allows the browser to handle the game's memory management more efficiently, reducing the stuttering (micro-lag) caused by Java’s intensive memory needs.
A: No. The entire client is served as a single HTML file and runs entirely in your web browser. eaglercraft 1.12 wasm gc
To optimize Eaglercraft 1.12 (the WebAssembly/WASM version), you need to manage how the browser handles memory and Garbage Collection (GC). Because Eaglercraft runs in a browser environment, you don't have a traditional

Concrete user reports indicate that on modern browsers like Chrome 119+, Firefox 120+, and Safari 18.2+, enabling WASM GC roughly compared to the standard JavaScript build. WASM-GC on Chrome, in particular, tends to run close to desktop Minecraft performance levels, with only occasional frame drops during world generation.
: Currently has limited or incompatible support for the WASM-GC runtime.
: It runs closer to the machine code on your CPU, bypassing the "laggy browser language" bottlenecks of JavaScript. Efficiency
WASM GC 是 WebAssembly 社区为支持自带垃圾回收的高级语言（如 Java、Kotlin、C# 等）而专门设计的一套提案。在 Eaglercraft 1.12 的上下文中，开发者不再单纯将 Java 编译成 JavaScript 运行，而是引入了这个现代化的编译与运行时标准。其核心目标十分明确：。
