From nethercore
Optimization techniques for Nethercore WASM games. Covers WASM binary size reduction (LTO, wasm-opt), texture and mesh compression, audio optimization, and state size minimization. Use when a ROM exceeds size limits or when reducing build output size.

```toml
Asset pipeline optimization, compression, streaming, and resource management for efficient game development and delivery.
Profiles and optimizes Unity game performance using Profiler, Frame Debugger, Memory Profiler; covers CPU/GPU bottlenecks, GC reduction, object pooling, batching, LOD, occlusion culling, and platform tweaks.
Guides importing and managing assets in Godot 4.3+ — image compression, 3D scene import, audio formats, and import configuration.

Typical savings: 20-40%
All textures use BC7 compression (4:1 ratio):
| Original | Compressed |
|---|---|
| 256x256 RGBA (256 KB) | 64 KB |
| 512x512 RGBA (1 MB) | 256 KB |
Resolution targets:
| Format | Size/Vertex |
|---|---|
| Position only | 12 bytes |
| Pos + UV | 20 bytes |
| Pos + UV + Normal | 32 bytes |
| Full | 40 bytes |
Poly targets:
// Use compact types
struct Position { x: f32, y: f32 } // 8 bytes
struct Position { x: i16, y: i16 } // 4 bytes (fixed-point)
// Fixed arrays, not Vec
entities: [Entity; 64], // Known size
