Meta Quest Runtime Optimizer issues

I tried the Meta Quest Runtime Optimizer utility and was inspired by the idea of integrating such useful functionality into Unity. On a simple test scene in my project everything worked well, but on a real complex scene I encountered several problems:


1) When I tried to capture a frame, the console displayed a warning 

[OVRNetworkTcpClient] Sanity check failed. PayloadLength 333694

and the frame capture has not happened. I tried deleting large parts of the scene (especially rigid body objects) and the frames were captured correctly, but it didn't help much. What could be the root cause?


2) "What if?" Analysis gives ьу confusing results: some objects report negative render time. Is it normal behavior and can I just ignore those reports?

    Does it also give you a stack trace leading up to the error?

    Yes, it happens in Core/OVRNetwork.cs at line 571 in ProcessReceivedData function.

    I have the same issue, did you find a solution?

    No, I didn't. The only thing that works is to simplify the scene considerably, but that defeats the purpose of the analysis.

    Hello there!

    I noticed you're running into some trouble with the Meta Quest Runtime Optimizer. Could you run the profiler and post the results? That way, I can get a better idea of what's going on.

    Looking forward to hearing from you!

    Hello GATORSAURU5,
    I'm currently having the same issue. Can you provide specific instructions on what you need?
    I can confirm that this issue occurs when trying to run the Runtime Optimizer (either mode) in complex scenes (for me ~1mio tris and ~2k parts).
