Research direction

Start with src/benchmarks/real-world/bepuphysics2/TwoBodyConstraintBenchmarks.cs, especially AngularHinge, and run the provided benchmarks_ci.py command using the DemoBenchmarks.TwoBodyConstraintBenchmarks filter. Compare the reported baseline and test results with the linked report and history. Done means the performance change is reproduced and its cause or required follow-up is established.
