Godot Engine now supports WebAssembly SIMD compilation, delivering significant performance improvements for web games. Benchmarks show 1.5x to 2x performance gains in normal scenarios, with even higher improvements during CPU-intensive situations. Starting with Godot 4.5 dev 5, official web templates will require SIMD-compatible browsers to maximize performance benefits, though developers can still build non-SIMD versions if needed for older browser compatibility.
