I use GPT-5.6 sol-xhigh to assist in the writing of this note.</p></blockquote> <p>To be specific, this note compares eight 3D-capable physics systems:</p> <ol> <li>Jolt Physics</li> <li>Box3D</li> <li>NVIDIA PhysX 4.1</li> <li>Havok Physics</li> <li>Chaos Physics in Unreal Engine</li> <li>Bullet 3 / the Bullet Physics SDK</li> <li>Valve’s Ragnarok / Rubikon lineage</li> <li>Rapier as the additional modern comparison</li> </ol> <p>The focus is real-time game development: rigid-body dynamics, collision queries, characters, vehicles, ragdolls, destruction/deformables, large worlds, networking, authoring/debugging, deployment, and predictable frame cost. Robotics-only accuracy, differentiability, offline finite-element analysis, and film-only solvers are outside scope except where an engine deliberately spans those uses.</p>
