BepuPhysics 2
Shares rank 5 of 7 physics engines by recommenders
A fast physics engine for C# game projects that people praise for its performance. Caveat: its design is hard to integrate, and it does not work in Unity.

Design is hard to integrate
“Their design is difficult to integrate with but the performance is insane.”
