2022 didn't Improve Playback for NVIDIA on Windows

[da7rutrak]

One of the 2022 features touted was improved 422 10-bit playback: https://helpx.adobe.com/premiere-pro/using/whats-new/2022.html#playback however this does not affect Windows PCs using NVIDIA GPUs, like the RTX 3000-series. 

NVIDIA clearly has the NVDEC support for it (https://developer.nvidia.com/video-encode-and-decode-gpu-support-matrix-new) yet Adobe Premiere Pro still doesn't make use of it. 

My EOS R5 Footage shot in 4K ALL-I in CLOG3 does not use the GPU during decoding. On the other hand, my EOS R footage shot in 4K ALL-I in CLOG does use the GPU during decoding.

When will Windows and NVIDIA users recieve an update to enable this feature? It's frustrating that Apple silicon-based MacBooks are already getting support.

Hello da7rutrak,

This appears to be a bug that we have just found and are reporting on now. Can you try a different playback quality besides the default of 1/2. Try Full or 1/4? What happens then? May we have more computer info, as well?

Thank You,

Kevin

[da7rutrak]

Thanks for replying Kevin! Playback at 1/2 anecdotally appears better than 1/4 or 1/8th. Full is about the same, IMO.

Hi Kevin, any feedback on the bug report?

I had the same problem. Premiere Pro 2022 was unable to play 4K videos at any playback resolution. Then I reinstalled PP2021 and strangely, the playback problem in PP2022 was solved. I guess adobe forgot to integrate Nvidia GPUs in version 2022 😅

I don't think Premiere Pro utilises Nvidia GPUs properly at all on the decoding side. I see 0% utilisation on my GPU decoder chip with 8 bit, 4:2:0, x264 and HVEC files on my timeline, when these files should be supported.

It's such a let down. I have a 16 core Ryzen AMD CPU & an RTX 3090 so can't use Intel Quicksync (which I've heard works for hardware accel decoding in Premiere). I have insane hardware resources that aren't being utilised in Premiere, so I'm suffering with poor performance on the timeline and am forced to make prores proxies to get acceptable performance, while those with cheap intel machines with iGPUS or (much less powerful) macbooks are flying in comparison.

Nvidia will never support 4:2:2 hardware decoding no matter what. Even more odd is that Nvidia technically supports 4:4:4 hardware decoding; however, I have yet to see a program that properly supports 4:4:4 playback even in software.

At any rate, NVDEC has been broken since version 23.3. Version 23.2 was the last version whose NVDEC worked properly.

[Koroku92]

Confirming that NVDEC is completely broken for me on rtx 3090 in Premiere Pro version 23.4! I hope Adobe fix this ASAP and keep it as a supported feature.

All my content is 8 bit 4:2:0 HVEC so it's a very useful feature for me (I wish it worked!).
