Do you consider making a physics engine (for RL) worth it?

• rapier

  39 3,574 8.4 Rust

  2D and 3D physics engines focused on performance.

  

Not a direct answer to your question but have you taken a look at Rapier? It doesn't have GPU parallelization but it does have SIMD support and CPU parallelization.

• dfdx

  22 1,611 8.7 Rust

  Deep learning in Rust, with shape checked tensors and neural networks

Shameless plug for my crate dfdx https://github.com/coreylowman/dfdx for auto diff, more similar to pytorch than jax though.
