Performance issues with Premiere Pro on powerful PC

I'm a freelance video editor who edits very time-sensitive videos on a daily basis.  Because of this, I needed a PC that would edit whatever I threw at it without issue.  This is why I have an AMD Ryzen 9 3950x processor, 48 GB of ram, a 2080 super graphics card, and an NVME SSD that I import and export video files from.

 

And yet, despite this, my 5-year-old laptop with an Intel processor and a GTX 960 graphics card is able to edit better.  When editing on the new PC, there is a significant delay between when I press the space bar to play the video and when it actually starts playing, and it's even worse for pausing.  This slows me down significantly, and as I said, the videos I edit are very time-sensitive.

 

This happens even at 1/4 resolution when the laptop edits more efficiently at 1/2.  I'm aware that pre-rendering the timeline or creating proxy files is a way to get around this, but the footage I'm editing from is an hour and a half to two hours in length, and even low-quality proxies take 30-40 minutes to render it.  Again, time-sensitive video.  I've put way too much time and effort into building this PC for it to not do even basic editing on 720p footage properly.

 

I read the other forum where a user had a similar issue, and yes, the video files are encoded in H.264, and I understand that the AMD processor doesn't support Intel Quick Sync, but it's a 16-core processor, and Premiere barely even pushes it past 2% use.  There has to be something that can be done about it without having to replace the entire processor and motherboard.

Things to check

1) Do you have VFR footage on a timeline? Use MediInfo tool to check. It's highly recommended to transcode such clips to CFR before editing. Tools ppl use for this: Handbrake, Avidemux, ffmpeg, nvencc, or build-in Windows editor

2) Try to turn off Hardware accelerated decoding in Preferences > Media...  It's recommended to clean media cache each time you change that settings,  or after any app update. Close PP and manually clean media cache (goto  %USERPROFILE%\AppData\Roaming\Adobe\Common  and clean/delete folders Media Cache, Media Cache Files, PTX, Peak Files)

3) Make sure that NVidia G-Sync is off in driver control panel

4) Make sure you are using NVidia 'Studio' driver and not 'Game ready' one

5) Try to reset workspace: Window > Workspaces > Reset to saved layout

Thank you so much!  Turning off hardware accelerated decoding and clearing the cache did the trick.  You're a lifesaver!

You can use software only encoding but you are not taking advantage of your hardware. I would try a BIOS update and a driver update. That being said I am also going to recommend you contact AMD. This seems to happen all the time with AMD CPUs and Nvidia GPUs. Maybe there is a chipset patch.
