Bug - Premiere Pro 15.0 using 100% CPU usage to load thumbnails and causing instability
Premiere Pro is hanging my system - 100% CPU usage when generating thumbnails in bin. Eventually it will go back down to normal usage, but if I try to do other things while this is populating it may cause my computer to BSOD. Last BSOD (this morning) was KERNELSECURITYCHECK_FAILURE
I should note that my system has 0 stability issues doing anything else except when using Premiere Pro.
This just started after the last update to Premiere Pro (15.0)-
This does not happen with 14.9
I am able to recreate the hanging and or crash by opening a folder and generating thumbnails.
This happens with 4K timelines, 1080 timelines and with 4K footage, and 1080 footage.

Yes, 15.2 has fixed the issue - and the new update to Encoder also fixed an issue where WMV files were failing to export.

@nic SMT is enabled here. I didn't change any settings. Tested 15.1 just the other day and still had the CPU spike issue. I didn't even have to clear cache and 15.2 is running great so far!

@michael 15.2 works for me as well, but I also turned off SMT before I updated so I wasn't sure what actually fixed the issue. Do you have SMT enabled?

Just installed and tested PP 15.2 and it seems to have completely fixed the CPU spike when importing media/loading thumbnails on my Threadripper 3960x! Program is stable and running extremely smooth for me.

Just for testing - yes this still occurs after the new Nvidia Studio driver update today.

Same issues on 3970x threadripper. Once I install 14.9 everything works great

Edit - this only happens with version 15.0, NOT 14.9. 15.0 is causing 100% CPU usage to generate thumbnails and throttling machine and causing hangs. 14.9 will use 30% of CPU and create the thumbnails almost immediately.
Edit - further testing with a brand new project leads to more CPU 100% usage and hangs when even closing the project trying to clear the cache - https://youtu.be/Y_fRAJiNh9g
Update - I tried uninstalling 15.0 - manually deleting the entire cache folder, rebooting Windows, reinstalling 15.0Same issues - hanging 100% CPU usage. Closed it down, opened 14.9 no issues at all, very fast thumbnail creation and very low CPU usage.
