Horrible playback performance even with Proxies

Hi!
Sadly since today, i can not get smooth playback, even with Proxies at a quarter resolution, and DNxHR LB that normally works very well but right now i simply can not work.

The proxies are on a SSD

I work on a AMD Ryzen Threadripper 2970wx with 64gb DDR4 RAM and i have a RTX 3080TI which, like i said normally works.

i turned off the grading etc. nothing helps ... any ideas ?

If it running fine before and suddenly starting behaving this way, it may have been something that got updated that is running in the background.

I had a similar issue. I was on Windows. This may be relevant for any OS though. I checked system performance and Windows was utilizing 98-100% the SSD because another program initiated some process. Perhaps you need to check if you have a service or program that is accessing the drive. A simple thing you can do is to turn off services you don't need running in the background.

If possible, edit the Startup Services of your OS and restart with the changes to see if that has an impact.

Thanks a lot! so far i have not found the reason, i have seen that my prahics card is maxed out all the time even when using a quarter resolution proxies, and deactivated grading... the taskmanager does not show where this comes from... any other ideas ?

Thanks i tried it and in the meantime i updated the graphics card and davinci, and the graphicscard is maxed out in my case, but even with proxies, turned off effects and grading at a quarter resolution i can not get smooth playback not matter what i do. Since i posted that i have to cut, export see the mistakes get back into davinci and this is insane, everything takes forever right now. Any ideas ? when i stop playback the gpu is back at 1% but it goes to 100% immediatly when i start playback

Try exporting the project and reimporting it as a new project, with a different name, like name-V2. Don't include media cache or sources, just the project. Make new proxies for that project and see what happens. I'm sure there is an easier solution. Since my suggestion only take a few minutes to try, it may help to reveal if it is the project or something else.

Are you on 19? This has been widely-reported on 19 and I've experienced it myself. Similar system.

I find that if you make a cut and wait as long as you need for the cache to catch up, it usually plays back at a good 4-8 fps. You should be able to make a dozen or so cuts every day. (Pardon the sarcasm but it's just not acceptable that everybody is having this issue. I'm struggling to edit 4k BRAW... the format made by the maker of the editing software... while the disk test says I should be able to edit 12k. Blender and Unreal operate at full speed with zero issues.) I've also found that CapCut rips through anything without slowing down and I'm having fun editing again using it! That may be the future...

On a less sarcastic note, locking picture on 1 video track and only having 1 audio track before doing anything else should help quite a bit.

The Problem was before updating to the new version. I had one day, yesterday, where everything worked fine. Today i am beack at horrible playback. It seems even though the proxies are made and activated davinci does something different and the preview is not the proxies.

I have 2-9 fps working is literally a nightmare right now.

I have the same problem. I've only 2 short clips on the timeline. I've tried proxy's and the playback is the same. If it can't handle proxy files we're screwed.

davinci switches from running perfectly to horrible in a manner that makes it impossible for me to find the reason, it does not matter if i work from my external or internal drive if i turn on and off proxies etc. it is like it sometimes simply does not siwthc to the proxies it created an now i have to work with 9 frames a sec playback and nothing helps

I wonder if anything changes after re-seting your GUI. From time to time I have similar issues on two Win10 machines and it always works.

Could you try to disable Neural Engine optimization in the settings.

What i saw is that my cpu usage at 100%.

Do you have ReBar activated in your BIOS settings? I tested that once and activating on that on my AMD system did not go well with Resolve.

There are also new Nvidia studio drivers 561.09 - WHQL out, with optimizations for Resolve 19:

The September NVIDIA Studio Driver provides optimal support for the latest new creative applications and updates including HEVC support for Twitch, support for a variety of NVIDIA AI features in DaVinci Resolve 19, NVIDIA TensorRT support in the new Adobe After Effects plugin for Topaz Video AI, and the introduction of RTX Video Super Resolution and HDR support in the Opera web browser.

Thanks! that is already turned off

No i have not actived that :/

Davinci still, becomes unusable at random on my system, it works well without any proxies, and all of a sudden i need proxies at a quarter resolution to get ANY playback... sometimes 11 fps even without grading ...

... and it is back. Proxies at one eighth no heavy color grading, and even with grading turned off maybe 9 frames a sec. Playback resolution is also a quarter. It appears so random it is horrible

Here's another simple thing to check.

Check your power settings profile and see if Fast start-up is set to default. If it is, turn it off and restart your computer.

You can find it it Power Options - > Choose what the power buttons do.

If you are on WIndows, make sure Windows Defender's Real Time Protection is turned off. Sometimes windows updates would re-enable it for me and nerf anything that used File I/O.

It sounds ridiculous, but just turn off Bluetooth.

I've been dealing with the same issue for weeks to the point where I could barely work, and I think I’ve found the solution. Like many others, I’ve tried absolutely everything: reinstalling the software, updating Windows drivers, and even DaVinci Resolve itself, along with every little tweak I could find online.

This morning, everything seemed to be working fine until, to my frustration, it suddenly stopped. I realized it happened right after I unplugged a USB keyboard from my PC. I spent the entire day trying to replicate the issue, but nothing worked—until I remembered reading a development forum discussing issues between DaVinci Resolve, Bluetooth, and Windows' power management.

As many of you might have experienced, the problem wasn’t just laggy playback; the entire interface was sluggish. That made me think: maybe Resolve was trying to connect to something in the background. So, I turned off Bluetooth, and immediately everything started working smoothly again. When I turn Bluetooth back on, the issues return.

It’s a strange fix, but it works. I hope this helps someone else!

Weird. It might be Windows, though.
Yesterday my external BT keyboard drained its batteries, and I simply continued to work with the laptop's one. No issue at all.

I'm struggling with this same issue. I just bought Studio and it's a bummer.

I'm processing a 30 second clip (.MOV 4k 120p 422) with 2 nodes, DKeyer1 removing bluescreen and a Tracker with 2 Intellitrackers.

In the fusion screen:
Playback speed with proxy disabled:
5.6fps with Timeline Playback Resolution = Full
31fps with Timeline Playback Resolution = One Quarter

Playback speed with proxy preferred, generated on internal SSD, DNxHR LB at Quarter resolution:
7.3fps with Timeline Playback Resolution = Full
40fps with Timeline Playback Resolution = One Quarter

If I try to generate a proxy at Eighth or Sixteenth, I get an error saying proxy generation failed.

I tried a bunch of Optimized Media settings and all of them resulted in worse performance than the raw file, like <1fps.

I tried caching the nodes to disk and didn't see any improvement.

I attempted Prerender but bailed because it said it was going to take 40 minutes.

IT worked for a while for unknown reasons, now i added subtitles aaand i hab 1.5 frames per second EVEN IF I DEACTIVATE THE VIDEO so only audio and subtitles... i do not knwo what else i shoudl do especially when it works well for a while and all of a sudden performace drops totally. I s there something like a resource monitor inside davinci ? like in Steinberg Cubase ? that way i could simply look where the bottle neck is, because nothing is maxed out in the process tab of the task manager.
