Huge slowdown after RaycastCommand ( Physics.SyncBatchQueries )

Hello, I'm hoping someone can help me understand what is going on in my App.

I'm making a huge number of Raycasts with RaycastCommand, it's all working but the problem is that my game still freezes because for some reason Physics.SyncBatchQueries halts the main thread execution until they are done.

The freeze occurs when one of my rigidbodies tries to move (unrelated to the raycasts)



And this is another view, I am not sure why one of the raycast commands seems to be executing on the main thread, maybe I'm just reading that wrong.



Could anyone please help shed light?. Version is 2019.3.10f1
Thanks!

 

I thought so too and tried that, but it still does the WaitForJobGroupID and freezes the app.

I'm assuming that this wait is intentional, if a rigidbody moves when there's pending raycasts to do it all waits until they finish to guarantee that they execute in the same physics state when they were requested.

In my case, that wouldn't really matter but I understand if this is why there's a wait. The documentation doesn't say really what happens in this case so I was confused.

I'm in the process of splitting up the raycasts in batches so this stops happening, so it shouldn't be a problem but It'd be nice to know what's really going on.
