Running this version in a browser is significantly harder than 1.5.2 because the game codebase is much larger and more complex. WASM GC makes this feasible by keeping the binary size relatively small and the execution speed near-native.
Removing the embedded software garbage collector yields smaller offline HTML and client downloads. eaglercraft 112 wasm gc

For developers working with wasm_gc , optimizing performance goes beyond simply enabling the feature. The complexity of Minecraft means that even with automatic garbage collection, improper object lifecycle management can lead to high memory usage and performance drops. If you want to tweak your setup or
Here’s a technical write-up on , focusing on how garbage collection in WebAssembly changes performance, memory safety, and practical deployment for this browser-based Minecraft clone.
To understand why performs so well, it is necessary to examine how WebAssembly handles data. Traditional WebAssembly operates strictly with a linear memory model—essentially a massive, flat array of raw bytes. Because Java is a garbage-collected language full of complex objects and references, compiling it to traditional WASM required a complex engineering workaround: embedding a software-defined garbage collector inside the game itself.
