VRAM is full immediately

VRAM affects performance. The more VRAM, the better overall performance, the less VRAM the less overall performance.
Please, show me a benchmark. And can you explain to me the mechanics behind it.

Please note that I said "overall performance" not speed .. so what is your definition of performance?

Which aspect of performance is better?

CUDA is not using that shared memory. I'd be curious to know what IS using it.

I'm also curious what you are doing that's using 24 GB of VRAM? Something like an 8K or greater timeline resolution?

Nonsense....

I am rendering again right now and Now DR using 7GB of shared graphic memory, when I DR turn down used memory drop to 0.1GB... So Davinci normally using that memory... but maybe not in an efficient way

I think I will buy M2 Ultra... I have enough PC problems...
But jesus 255k CZK... it's 10200€

Other user can work with their PC, you have to discover what are you doing differently.

Are you add too much effects?

I edit 6k braw q5 and q3 on my notebook rog with a 1070 8gb, in a timeline 4k. 32gb of ram and a worst i7
Editing, color and more

The same on my hackintosh with amAmD vega64 with 8gb of vram, 48 gab if ram and i5 5600k
here I can work up to 12k braw in dual stream, no more or it suffer a bit.

On both I can work realtime, obviously if I add external denoiser like neat video or other heavy fix I should wait a bit to cache it, but I know and do it later or when I do the final pass.
But classic work of editing and color correction all work realtime without full of vram.

You have a faster computer than mine, it should fly.

Well, it is not a "PC problem" .. you are facing problems with your PC... and it might be a problem with your setup and configuration. So switching to Mac is not answer, but good luck if you decide to switch.

BTW .. don't expect the Mac to be problem-free .. any hardware or software has its share of problems.

Right. While on a Mac you have fewer combinations and all from one manufacturer, you might be disappointed if you expect it to be trouble free. Rather try to get to the bottom of your issues with a PC specialist.

I do not know if I will buy M2 Ultra. It's a lot of money.
But my post-production really need some upgrade and I do not know what my Resolve actrually need.
128GB RAM, RTX3080 12G... and it's full of problem. Maybe I switch just to AMD Threadrepear platform for 2 RTX4090 (My work is RAW only, BRAW and CRAW)

While CRW can be quite demanding compared to BRAW, both of these should work well on your hardware up to 4K. Something must be screwed up in your config.
I’d still assume an issue with your other GPU. Since it won’t help with decoding anyway, could you try with only the 3080 enabled?

Nothing is wrong with your computer specifications, but something is definitely wrong with your configuration or workflow, assuming your hardware is not defective.

What brand is your PC?

PC brand? I have custom PC...
Now I rendering the same project again to cache (braw + craw to uncompressed 10bit) and it works fine. BRAW seems to be MUCH MORE HEAVY for VRAM than CRAW. When I rendering CRAW only 7GB VRAM is used. When BRAW 100% VRAM is used and render slowing down.
That's probably because of 6K resolution? Or just BRAW is heavier format for VRAM than CRAW?

craw might be decoded using cpu while braw is using gpu decoder.

BRAW is using both CPU and GPU cores here. 12K runs smoothly on my laptop in an UHD timeline.

I'm also curious what you are doing that's using 24 GB of VRAM? Something like an 8K or greater timeline resolution?

I'm also curious to know that

Resolve on Windows/Linux with NVIDIA GPU's and CUDA processing can only use the dedicated GPU memory. Shared GPU memory is not available for Resolve to use.

I was able to get the Resolve out of memory error, but only after it used all my shared GPU memory, doesn't that mean Resolve does use shared GPU memory with Nvidia?

From my observation, Intel quicksync enabled DaVinci Resolve project is most likley the culprit for shared GPU memory overload which I hope can be resolved soon.

Performance is better I guess ¯\_(ツ)_/¯ Although I'm still curious what that "overall performance" means that isn't speed.

PC brand? I have custom PC...

Well, your custom PC could be facing compatibility/stability problem of some sort! Does this custom PC have a brand? Or you build it yourself?

Generally speaking, when it comes to workstation computers, going with a well known and respected brands such as HP, DELL or BOXX is much better and far safer bet than going with custom build, especially brandless PCs! Yes, such big brands are expensive and you will be paying a lot more but in return, you are getting piece of mind and optimal configurations and that you will not face compatibility or stability problems becouse such companies take the time (hundreds of hours) to test every component thoroughly to make sure all components are fully compatible with each other which translates to a very stable system.

If it is a gaming PC then no problem going with custom-build or even brandless PCs but for workstation work, getting trusted workstation brand such as HP and paying the extra money is worth it.

Also, it is not fair to compare brandless, or custom-build gaming brands PCs with Apple computers .. you need to compare apple to apple .. so you must compare Apple computers to its equivalent from big and well respected companies

Speed is just one element of performance. Performance includes many elements and factors such as speed, stability, efficiency ..etc. So even though the amount of VRAM does not increase the speed of, let say playback or rendering of specific timeline, it has big effect on overall performance which may includes the overall speed.

Search Google to learn the difference between performance and speed.

Second that! What's a machine worth that may run faster – as long as it runs – but crashes more frequently?
You end up with less work done.

Good point .. a slower but stable system may end up faster than a faster but unstable system .. that is why speaking of speed alone is not enough ..you need to evaluate and put in mind the overall performance.

The file was 8K HEVC 4:2:0 10bit camera file on 8K timeline using only a single plugin - Neat Video Noise reduction. So I was thinking the BM employee was probably correct and it was the OFX plugin using the shared GPU memory although I saw another user disagreed and showed Resolve using shared GPU memory without an OFX plugin.

You really don't want to go down that rabbit hole. The big box makers all cut corners that would embarrass any serious home builder. They cut corners every place they think the specs won't show. Everything from cooling to PSU to using non standard parts.

Seconded.
If you don't dare to DIY, go to a serious system integrator, who has a proven record track for DR systems.

thirding, for what it's worth

i found that being on the cutting edge was akin to bleeding to death ;-(

CRAW also use GPU. CPU almost sleep.

12K BRAW has smoth playback on your laptop? Guys stop be toxic...

Braw decoder only decodes at 4K res on UHD timeline, which is a lot faster and lightweight than full 12K res decode.

I don't think that's entirely true because I just tried using some demo 12k footage from BM here and I do see a difference in playback speed when I select "Decode as 12k" and "Decode as 4k" in the RAW tab of the color page. (All while the clip is on a 4k timeline).

If you manually force it, then yes. But if project settings is set to full res and decode quality is set to use project settings, which it defaults to, I'm pretty sure it internally decodes at the closest larger res and rescales that to timeline. Question started from whether 12K braw can play on a laptop and yes, it sure can, as 4K decode is way lighter than full 12K decode. So unless Uli forces the decode to 12K it surely can play fine.

Of course Nick, every company on earth do cut corners to balance between, let say quality or performance and cost. So the question is not whether corners has been cut or not, but to what extends has been cut! That is why I said it's "safer bet" to go with respected and well known companies when considering serious workstation computers.

As an electronics engineer, I built my first PC in 1990 and built my first high-end water-cooled workstation in 2000 and all worked great for so many years. But when it comes to serious work where clintes depends on, I don't take risk and rely on my building experience, instead I go with one of the reputed companies.

During the last 23 years, I have purchased and used for my work multiple high-end workstations from Silicon Graphics, Intergraph and HP and did many quality and performance comparisons between them and my custom built workstations. I can say with confidence that those workstations from Silicon Graphics, Intergraph and HP were much more stable and provided much better overall performance even tho my custom built workstation had better specs "on paper".

That does not mean you will never face any system problem if you go with one of the big boys becouse perfection does not exist in life. However due to the extensive compatibility testing and the optimizations those reputed companies do, it translates to superior stability which equals less problems and better overall performance.

That's not a GPU, it is an IO card for sending and capturing video signals.

But it has a tons of encoders for smooth playback. For playback you always do not need tons of 3D rendering power...

Encoders are strictly for encoding. That is not decoding or processing FX.
Resolve utilizes the GPU for decoding, encoding, FX processing, color transforms, and as well as 3D rendering. Basically, most of the workload is done at the GPU level with some exceptions. Video I/O cards are just there to get a baseband signal in and out of your computer.

I seriously doubt Decklink card would do anything useful in Resolve processing at all, except in relation to signal IO, no matter what kind of encoders it might have internally.
