Power Profiler + PPK2 slow on version 4.1

Hi. I'm on a relatively old ryzen-5 windows 11 PC and I get 30 FPS when recording power with Power Profiler version 4.0.0 and 2 FPS when recording with newer versions (4.1.<0,1,2>)
Don't really know what to do except keep the old version.

  • Hi Jason,

    Are you using Windows 11 as well?

  • no, windows10.

    It's fine when I roll back to 4.0.0. 

  • I see these processes

    Almost no GPU usage

    or CPU usage 

    RAM and IO etc look normal. 

    I ran a VS2022 performance diagnositc and I've attached the file. Maybe a developer can load it. There's no symbols unfortunately. 

    The fact that it shows less than 1% CPU or GPU suggests its waiting for something, or it's in a system call.  That's my guess at least
