With ongoing development and fine-tuning, it can overcome its limitations and reach full potential. I should also note that Rapier is actively maintained and shines for its simplicity and ease of use. Considering that it’is built using Rust, I had high hopes for blazing-fast performance, but it seems to be on par with Ammo. Rapier on the other hand, falls short in terms of accuracy, especially evident in the ragdoll, mass, and diamond simulations. If am not mistaking, it has two settings, one slower option for backward compatibility and broad device support, and a more performant setting for modern devices. While I don’t notice the promised 50x performance gain, there is a noticeable improvement with the keva demo. Havok seems to perform well, with precision comparable to or possibly better than Ammo in the “test” demo’s friction section.
