Premiere just using 30 % RAM

When i play my timeline in premiere, it just uses around 60 % CPU, 30% RAM, and 5 % GPU and mostly 0% HDD, sometimes more but goes down to 0%.

I use Mercury Playback Engine.

Preview Cache option is faded out (GPU preview cache Oo)

Of course the timeline cant be played in real time.

But many effects just dont get played.

But why isnt premiere using more CPU, GPU and RAM?

I have made option that it can use 26 GB RAM.

Still its using just 30% while after effects is using around 75%.

I would have no problem if it would use 80% RAM, 85 % CPU and a lot more of GPU if that makes the playback faster and smoother.

I have newest GPU driver installed.

I have Threadripper 1900X, SSD, 32 GB RAM, GTX 1080 TI.

    Correct answer Christian.Z

    cleaned the drive now i have around 90gb free, but its just a little faster and same ram usage.

    always thought that that its not relevant how full drive is with ssd drives

    i will try to use smaller project files (resize them before putting them in premiere) maybe it will help a bit

    When i would buy another ssd, what speed should i choose?

    current has

    3,200MB/s Seq. Read

    1,500MB/s Seq. Write

    can i buy slower cheaper ssd?
    premiere should be on fastest drive?

    Maybe ram usage will be the same with new ssd, who will know that.

    what ram usage do you guys have in premiere?


    I'll Lay it out for you. Premiere uses RAM and CPU as much as it needs. It uses the GPU to playback non-rendered clips and to render GPU accelerated effects. However when all of that is happening, Premiere is Reading AND Writing to several things at once. If all of those several things are located on one drive, Premiere will be slow. It may try to use more RAM or CPU since it's working harder to read and write.

    If Premiere is using 30% RAM, it's because that's all what Premiere needs. If you have a better storage configuration, it might even use less. Each of the components has a specific task to do, and all of your components are doing their tasks correctly, except storage. At the end of the day, no matter how powerful your system is, it is as strong as the weakest link, in this case Storage.

    As for what SSD to buy? When I built my system, I bought the cheapest 2 SSD I found, it was 500gb Kingstone. One for the OS and all my software (To answer your questions, Premiere should be on the main drive, and the main drive should be an SSD), and the second SSD for the Cache files and exports (Plus some personal random files). DO NOT SAVE YOUR CACHE TO THE C: DRIVE.

    And for the Media files, I prioritized capacity over speed. I bought 2x 2tb WD Black and striped them as RAID 0. I also place the project files there.

    I am not really sure what you mean by that. When you go to File --> Project settings, what does it say next to tenderer?
    For the GPU acceleration to be enabled it should say "Mercury Playback Engine GPU Acceleration (CUDA)"

    Your system is really powerful, Premiere is using this much because this is only how much it needs, However you might be bottle necking with the Storage and Rams.

    First let's get the GPU helping out in Premiere and we can figure out what's happening with the rest.
