Why DOTS Is Unity's Silver Bullet
summary
Claims DOTS (Entities, Jobs, Burst, NetCode, Havok) delivers real, measurable speedups — Burst often gives ~10x improvements and Jobs parallelize work across many threads — and ECS stores components in 16KB chunks for cache-friendly arrays. Demonstrations include a modular projectile system built by composing capabilities, a VR graph simulator scaling from ~100 to thousands of nodes, and generated ECS boilerplate expanding a small system into ~175 lines. Roadmap items: ECS-for-all, unified transform, and a new DOTS animation pipeline.
