    hello, i am getting big spikes in the profiler when Physics.processing is calling `PhysX.BpSAP.postUpdateWork` and `PhysX.BpSAP.updateWork`. What is causing this ? What can i do to resolve it ?

    I am using unity version 2018.4 and i am profiling a build (not playmode in editor).

    I think I may also have seen them briefly in 2018.4, after that I upgraded to 2018.4.1, and ended with UpdateDepthTexture spikes. Can you try to update and provide feedback?

    I upgraded to 2018.4.1 but i still get Physics.processing spikes after some minutes without any reason.
    I sent a report to unity and i am waiting for their answer.

    I can't tell for UpdateDepthTexture because spikes seems to be related to different calls so it's too difficult to say it's because one thing.
