V19 BRAW results - anyone getting 4K playback 24fps even at draft?

I realize it's beta, but there is not much in help or docs to clarify what state it is in. I just shot a microbudget feature with Pocket 4K with anamorphic lenses. I can load BRAW files no problem. And I even see a slim collection of LUTs in color grade.

But on my system i7-7820x with 122GB RAM and 2080Ti,

in 8-bit mode (GPU on) I get 18 to 20 fps in everything from Best/Full to Draft/Quarter which tells me something is hard limiting it. However, 8-bit defeats the purpose of shooting 14-bit raw...
In 32-bit mode (GPU on) i get 4fps in Preview/Auto, 6fps in Draft/Auto at 8fps in Draft/Quarter, not usable at all (but stills look good!)

Premiere Pro get's full rez, 4K playback with high color depth and quality on, drops a frame now and then but 24fps seems pretty solid for one track, so not bad.

Resolve 17 of course plays back, even with fade/dissolve and LUTs with no problem so will continue to use that for editing this feature.

I'm wondering if RTX 3080 Ti will hit 24fps.

Gentlemen, Remember that the new Braw implementation is still in Beta phase, so you will see some limitations popping up. It will however be updated soon out of Beta to encompass all the necessary features !

I don't see very high cpu utilization on either machine (about 25%) or any gpu encode or decode. But a lot of gpu copy. Up around 60% on the Vega64. Odd part is I only get about 15 fps on a 9900k machine, similarly low cpu utilization, and about 55% copy utilization on it's Radeon VII which is a faster gpu with 2x the memory.

I've seen copy on intel systems running Vegas, I figured it might have something to do with using the Intel GPU for decode and another GPU for processing, and the need to move data between them.

Modern raw codecs like Black Magic and Apple Prores can be decoded by the main GPU processor not the GPU video decode and takes the load of the CPU. VP19 is dropping frames without using much of my GPU or CPU, the same that you are experiencing. On Premiere it will use more CPU then Vegas uses and not drop frames

I just now realized, it does create automatically proxies for 6k footage. which means you most certainly get even on mid range computers in preview auto smooth playback. So if you really want to know if playback is possible, you have to change the resolution in the 'internal' options (click and hold shift then settings), or use anything above preview modes.

I always have the auto proxy creation turned off.

I must be really blind on that regard. Please help me, where is the option to turn it off.

Hidden in plain sight, although between lines. No idea why i could not see it. Thank you.
