Power Profiler + PPK2 slow on version 4.1

[magnusE]

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 and Mathew,

Could you please try the following and let me know.?
Try recording for 5 minutes using version 4.0.0 and version 4.1.2
Do must make sure that you rely on some external clock to count the 5 minutes and not on the timestamp on the ppk app.

Ideally, we expect to see that after 5 min the version 4.0.0 will have less time recorded and version 4.1.2 will have the correct time. 

Regards,

Swathy

For me running 5 minutes with 1000 sps and using my phone stopwatch to time stuff:

------------------------
version 4.1.2

2-4 fps, always
5 minutes realtime gives 2:28.1 minutes ppk time
-----------------------
version 4.0.0

28-32fps, always
5 minutes realtime gives 2:28.2 minutes ppk time

--------------------

Interesting issue.

Changing usb ports (annoying on stationary computer), but worth a try.

--------------

version 4.1.2

26-31 fps

5 minutes realtime gives 5:00.1 minutes ppk time (works well)

-------------

version 4.0.0

28-32fps

5 minutes realtime gives 4:59.8 minutes ppk time (works well)

--------------

So my issue is with a specific usb port. But I regularly use this port for data transfer as well so I believe it 'works'.
