ProRes RAW Premiere Pro high CPU usage, stuttering playback. Was working fine on different version.

Question

Hi as the title says. I was testing out my new GPU (4070 Ti) in Premiere (not exactly sure what version) the other day. I could play back nine 6K ProRes RAW HQ streams simultaneously at full quality without a problem with low GPU and CPU usage. For unrelated reasons I had to clean install Windows 11 and Premiere Pro and now I can barely play back 2 clips with 100% CPU usage.

Mercury GPU renderer is enabled in the Project settings and I have tried all sorts of other codecs. The only two formats I have around are AV1 and H265. Premiere isnt even compatible with AV1 and H265 plays back worse than ProRes RAW. I am 100% certain I was testing 6K ProRes RAW HQ and not something else. All of my SSDs have at least 2GB/s read speed.

Interestingly Premiere gives a warning to enable GPU rendering for ProRes RAW when I load the clips, but it is enabled and if I disable GPU rendering performance gets even worse.

I don't know if its the NVIDIA driver that has changed or Premiere but this is frustrating because for a moment I thought I had finally got a working system for editing ProRes RAW and now I am questioning whether it was really working or not.

My specs are 5950X with PBO enabled. Cinebench R23 gives a score of 28500.

32GB 3200mhz RAM XMP enabled

RTX 4070 Ti

X570 motherboard

This occurs on

Adobe Premiere Pro 2023 v23.0.0.63

and

Adobe Premiere Pro 2022 v22.6.2.2

I have yet to update to Premiere Pro 23.2

Now I can't confirm whether I really had low CPU and GPU usage before but I can now playback 7 simultanous clips of ProRes RAW HQ with no frame drops in Premiere Pro Version 23.1.0. I can also scrub at least 9 clips smoothly. I have also updated to Windows 11 22H2 but it was still stuttering before I installed this version of Premiere Pro. Before it was barely useable. Since I thought I had 9 clips playing I am not sure what the full story is but its useable now at least.

So for anyone else who has a similar problem try these in this order:

Premiere Pro Version 23.1.0

NVIDIA 528.49

Windows 11 22H2

I have seen on other forums that Win11 has some current issues with ProRes RAW in a number of apps. Apparently more so on Nvidia GPUs, but that's a "perhaps" thing as far as knowledge goes at this time.

23.2 might do better, and/or a clean install of latest Nvidia studio driver. Two things I'd suggest trying.
