I have a RBD Sim with an RBD Car Fracture in it.

There are about 10k primitives in the scene at conclusion, and I am trying to get real time playback of the simulation.

I get about 8fps when using the simulation points / base geometry & then using transform pieces. This is about the same speed as loading from a regular file cache with the RBD I/O node.

I am saving the files to my main SSD hard drive, but I can't seem to troubleshoot why the load is so slow. Performance monitor indicates that the bottleneck is in the read_back of my filecache node that holds the rest geometry.

But I don't see why it should be that slow?

I am wondering if there is something wrong with the drive, so I tested - reads back at 3.5mb per second. Is that slow?

Any help would be great - thank you!

Your filecache1 is time dependent, assuming this is your initial state geo there is no need to write it for more than initial frame
So append time shift before, freeze start frame and cache a single frame instead of a sequence

Okay thank you!
