SIMD Acceleration Boosts Physics Engine Collision Detection
Box2D's latest post details how SIMD instructions speed up collision detection in physics simulations. The technique processes multiple collision checks in parallel, improving performance for games and simulations. Benchmarks show up to 4x faster collision queries on modern CPUs.

This is a practical optimization for game developers, but the real impact depends on how widely Box2D's SIMD approach is adopted beyond its own codebase.
