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

It's basically the same

with 4.0.0

After 2 minutes the elapsed time was 42s on the UI

After 5 minutes the elapsed time was 1:43s on the UI

But the chart refreshed at 31fps.

On the latest version I see almost the same behaviour, but with only 3fps

After 2 minutes the elapsed time was 38s on the UI

After 5 minutes the elapsed time was 1:41s on the UI

I'm plugged directly into my PC. I'll try another USB

[Jason]

I changed ports 2x but its the same .I also unplugged my jlink etc

I then unplugged my Bluetooth audio dongle and swapped my mouse with the PPK2 and now it's 30fps

[Jason]

and the elapsed time is about right also

the bluetooth audio dongle makes no difference.

Its just a different port. Both usb portas are wired directly to the motherboard.
