The export times of version 22 is slower than version 21

[litohe]

the latest versions of the software，2021/2022

the same project，the same export setting

the same PC cpu：  i7 1165G7

4k hevc 420 10bit to 1080p hevc

export time ：29s/2021   58s/2022

According to the latest feature update, version 2022 should export faster, but in fact, it can't play videos smoothly in timeline.2021 is very smoothly in timeline

why？？What might be the problem?

Hi there! Did you update this project from a previous version of Premiere Pro? If you create a new project in 2022, it may play your videos back smoothly. We do not recommend updating Premiere in the middle of a project. 

Let us know if a new project in Premiere Pro shows the same issues.

hi i tried to creat a new project in 2022, no any another actions,just import the same footage,still can not playback smoothly.

on the other side,Ver.2021 playback is very good.

I'm very confused 

Now it seems that the 2021 I installed is more like the latest 2022

hi i found some new useful information.i watched the task manager(windows11) when i was running 2021 and 2022

both new projects,same cilps,same settings

when i try to play back the footage in my timeline ,the task manager showed that cpu 20% utilization , discrete gpu 80% utilization , integrated gpu 15% utilization.2021 runs very smoothly.

But in 2022 ,i got 100% cpu utilization, 15% igpu and 0% dgpu.

i think this is the crucial reason that why i can not play back smoothly in 2022.

i hope this information can help you analyze and solve this problems
