Hey, my game server is built up on the basis of Tokio async runtime. so I want to call rapier api via the threads in the runtime instead of Rayon. Is it easy to let the api user decide the threading model of rapier collision apis ? Thank you very much !

Hi! It is not possible to switch to a threading model other than rayon when multi-threading is enabled for rapier. async is generally not considered suited for compute-heavy tasks where rayon’s work-stealing scheduler is more suited.

hey mate, my game dev is in and cpu heavy app at the same time. No good trade off for me. Either losing asynchrony support or losing rayon support. I chose losing rayon and do the dirty jobs of parallel myself. Anyway close now.
