9 fps playback speed after 17.4 upgrade

PostSat Oct 23, 2021 12:54 pm

Hi!

I get 9 fps playback speed on typical 4K h.264, h.265 even without any color correction after 17.4 upgrade. I've deleted cache files. Still unusable. Any ideas?

The 17.3.2 was perfectly fine and fast. Looks like a definite bug.

Mac Pro 2013, 10 core, 128GB RAM, 2x 6800XT eGPUs, Mini Monitor 4K, Monterey OS.
I had to switch back to 17.3.2 and get back to work.

First thing to avoid in production environment - beta OS and app installation on officially unsupported OS.
You just asking for problems for no reason.

No idea what is so great in Monterey that you need it so badly (specially when you use Mac 2013).

I know what's so great.
I've switched from Catalina to Monterey because of faster, more efficient eGPU performance.
The Monterey serves me well since summer with no issues.
The issue appeared when moving from previous 17.3.2 to current Resolve 17.4, not when changing the OS.
Resolve 17.4 is Monterey compatible release.

p.s. Don't call me baldy :D

It can't be as system is not released yet.
17.4 uses Monterey properly :lol:

H.264 and other highly-compressed codecs are intended as DELIVERY formats, not necessarily to be used for editing and final color. Using H.264 puts a lot of stress on the computer, since it has to de-compress the images and play them back at speed, in addition to applying all the processes Resolve requires. My advice is to transcode all the H.264 material to a simpler codec for your system, something visually-lossless like DNxHR or ProRes 422HQ, and use that instead. You'll get much better performance that way.

The alternative is to use Optimized Media, which basically transcodes it all in the background. My preference is to do it manually, because then I can control where the files go and how they're named. Proxy Media can also work very effectively (and is preferred in some ways).

Sure I know the theory.
The only difference is the Resolve version.
The question is do you think is it normal:

17.3.2 - great smooth editing/playback performance on 4K, no matter h264, h265, of course ProRes422, smooth playback, not a single problem

17.4. - Resolve playback is 3-4x slower, stuttery 9fps playback, without any color correction, same project, same settings, with deleted cache. Unusable

Just some compatibility issue, so needs fix with future update. You can send email with details to BM support so they log it.

It may not, so no GPU decoding and 9fps playback.

Of course!
With such a fast GPUs as double AMD 6800XT (internal D500 not used) the rendering is very quick. I can even playback better quality noise reduction + CC + sharpen almost in real time without the rendering/caching with C4K resolution using previous Resolve 17.3.2.

I hope so it's not a "planned obsolescence", it would be too drastic from 17.3.2 to 17.4
From great to no performance in one step.

The Mac Pro 2013 it's not a single core monster but 10-core Xeon it's a sweet spot IMO.
And with 2 fast GPUs on different TB buses it works fine in C4K.
So I can wait for the Mac Pro M2 in the future.

I've sent an email to BMD waiting for a reply.

THAT is my point: the eGPU is accessible by resolve in 17.3.x, but it might be screwed in 17.4

check:
1) is the GPU visible in the resolve system
2) is the CUDA/Metal?OpenGL correctly selected? (switch to another, restart, switch back to the right one and check again)
3) monitor what the system is doing while playing back: do you get the files on time (drives/bandwidth), do you deflated in time (CPU at 100% or more), did you process it in time (D5oo is active and the eGPU is not)

bonus: check if the h264/265 deflating processing is setup for GPU or CPU.

also, do not simply assume that because it was working in 17.3x is automatically setup correctly in 17.4, things changes....
