Beta 23.0 very high CPU use for Threadripper 3960X, playback fails

I'll let Fergus speak for Adobe - but for me I just run 22.4 to get rid of it - you can do that in Creative Cloud - All Apps - Premiere Pro - Other Versions - Install 22.4

Hi, Fergus and Nick - where are you on the flicker issue?  my FX6 files that are MXF are shortening my lifespan. HELP!  premiere pro 22.5, build 62. imac pro late 2017 (new mac on order!)

Still present in Build 28 (not a complaint, just for info)

Ah ok. Well I do hope you can crack it, so many cameras are shooting MXF wrapped AVC these days - the more of those we can add to the hardware decode supported list the better. I'm hoping Nvidia adds more support for different flavours in the 4000 series and I'm interested to see how the Intel cards perform - they may be getting bad headlines for gaming drivers, but Intel has always been great at decode/encode.

Thanks for your openness on it and glad you're pushing the boundaries and testing things - that's what the beta's for after all. Out of interest is it specific to the 3960x or all AMD or just everyone (with AVC in mxf wrapper)?

Hi Nick, 

We're debating internally about whether to rollback the component that's causing the issue you're seeing. On one hand, it breaks performance of AVC (including Sony XAVC) in the MXF container - which is bad - but it also fixes several other bugs. We'd like to confirm those bugs are fixed but, for someone using AVC in MXF, that likely won't happen because of poor performance. 

So, for the beta of v23 is probably not going to work for you. Our team is talking about this actively right now. 

Regards,

Fergus

And playback too - and it launches forwards and back within the shots (almost like it's playing back keyframes in the order they were encoded and not the order for correct playback)

Still getting 100% CPU in Build 19 - at least on project launch
