I discovered the severe lag of PremierePro 14.4 (having an impact on the whole Win10 2004 system) is caused by editing the Avid DNxHR HQX video format. And that did NOT occur on PremierePro 14.3.2 that worked perfectly fine with my DNxHR HQX UHD footage. Accidentally I started to edit a PreRes HQ 422 on 14.4 and everything worked fine. As fast as 14.3.2, as it should be.
14.4 must have problems editing the Avid DNxHR video format.
These are the specs of two of my files :

This forum is primarily user-to-user "peer" support. You have information that should get to the engineers who need access to performance data across the user base which is why they started their public beta program.
And the way to get that info to the engineers directly is via posting on their UserVoice system, which goes directly into the development team. At least one engineer reads/manages every posting their. Give the full data as you did here!
