Intel i7 6850K and RTX 2080 Ti but no CUDA accelleration on warp stabilizer

[Jofikahn]

GPU-usage stays as low as 1% whereas the CPU is doing the job. Mercury Playback is activated, newest Nvidea Studio Driver 431.70 installed (with 431.60 wasn´t better). Brandnew RTX 2080 Ti doing nothing. Same result I had on my old GTX 970 though... Using Mainboard AII X99 from Asus, 32GB RAM, SSD etc.

Analyzing is done on the cpu.

The analysis is done by the CPU, but the application of that effect after the analyzation involves the GPU.

Analyzing is not the same as rendering, playback and export.

Thanks people
I´m just too disappointed now. I bought this expensive RTX-Card to get things done faster. Unfortunately I use this warp stabilizer extensively while editing. Now it turns out to be rather useless. I think Adobe should better and clearly address this issue to help people understand what they´re going to spend their money for.

Analyzing is done in the background.

Just do a few at a time and you can continue editing.

Just discovered that for exporting H.264 Video (to HD from 4K) the GPU only uses max 15% of its capacity. Does that also sound normal for you guys?

GPU usage will depend on the project.  Scaling, number of effects, etc are all factors.

As you've noticed Premiere won't always max out GPU usage, especially if you're using one of the highest end GPUs. Results will vary depending on what you're doing in your project.

Re: H264 export. Premiere doesn't do all the rendering using the GPU. There are many different pathways.  In some cases, we can leverage Intel QuickSync to decode footage or accelerate the H264 export - In addition to using your Nvidia GPU for scaling or rendering effects. We can share the load between dedicated and Integrated GPUs.

We are also constantly working on other optimizations including optimizations related to CPU usage.  Lots of different areas for optimization and many things vary by project to project.

You might want to try making some proxies just to see things work. I have the same processor as you with an gtx-1070. Here's some screenshots making 4K -> 720p proxies and 1080p -> 1080p.

With the former, both gpu and cpu are at 100% (considering the scaling of the proxies). In the later, the gpu is only at 17% when no scaling is involved.

Thanks MyerPj
Sounds interesting and the grafics you´re providing are impressive. But I´m afraid I can´t follow you. Just stopping unnecessary system tasks doesn´t make a proxi, right? How or maybe where do I make a proxi "from ...."? And why should "making a proxi" force or allow the GPU to run at 100%?

[R Neil Haugen]

The example used demonstrates how the GPU is used. As MyerPJ notes, when doing scaling from 4k->720, the GPU is used heavily because it is being used some for the general process and a ton for the scaling.

For creating proxies with same-size as original media, so no scaling, the GPU use drops dramatically. As the process of basic encoding is mainly a CPU task.

And he has a number of links on the background processes one can eliminate in the OS Task Manager that reduce the load on the system/CPU so that Premiere can run faster. And of course, one of the reasons he gets the performance he does from the CPU is that 4.39Mhz CPU speed ... awesome!

Yeah, what R Neil Haugen​ said!

It's just something to try to see if your 2080 is being used. There's also a PP benchmark from Bill Gehrke​, but unfortunately he hasn't been around for awhile. His benchmark if you can find it, really fired up you graphics card also. So in lieu of that, try creating the proxies with a scaling and you can see if PP is using your card where it can.

I've got a BlackMagic PCC4k now ... and I love the files from that camera. Especially, I love the BRAW format. But even the higher quality ProRes has a very wide dynamic range, a very "thick" 10-bit file.

My poor machine here ... even on 1/8th res in playback ... stutters horribly with both the BRAW (using the Autokroma plugin) and the higher-Mbps ProRes files. It's only a 6-core I7-6800k at 3.4Ghz with 32GB of RAM. All "working" drives either M.2 or regular SSD. Spinners used for mass storage but not working projects or their media.

So ... I'm looking over the Puget Systems and Safeharbor Computing systems again. My builder done left the state, so ... I'll be just buying one from them. Sometime twixt now and October 1 I figure I'll pop the cork on it.

And ... gonna have it preloaded and tested by them (as they do!) for Premiere, AfterEffects, and Resolve.

Gonna take a chunk of change but ... I gotta get the work out, you know? Sigh. Neither Premiere, AfterEffects, nor Resolve work particularly spiffy on this "small" a rig. Not with that media, nor some of the RED I occasionally get now also.

Yeah, Neil - cheers!
It looks as if we´ll never get enough "operation power", though (especially concerning our budgets). After reading the newest tests from Puget Sys (and comparing the CPU benchmarks) I recon we´ll have to wait for some kind of "chinese wonder" e.g. quantum computer. I just read they recently patented an incredible amount of new inventions on this field...

Thanks MyerPj for your hints! Yesterday evening I tried some work with proxie. Previews and scrubbing is indeed a bit easier. The encoding of the proxies was done as quickly as expected on the 2080. But the main bottle neck remains the CPU (as you also mentioned). I´m thinking of selling the 2080 Ti and and getting some better CPU and board instead. Though I´m not quite sure which one to choose... even after reading the newest "Premiere CPU test" from Puget Systems...
