Premiere Pro Preview Process

Hi. I was wondering which processing unit does the premiere use for the Preview in the program monitor. Actually I bought a Nvidia 1050 2G gpu just to use CUDA tech and get rid of preview lag, and nothing changed so after activating CUDA acceleration in project setting, then I checked task manager and noticed that during the preview the CPU usage goes to 100% percent.

After some searches I read a post that said the only Adobe Premiere GPU of system requirements announced in the Adobe website would be used for preview. so is that true ?!

I'll express the contents of that document perhaps more directly.

 

The CPU/RAM system is the center of all computer work in Premiere, and all other gear on the computer is used to assist and enable the CPU/RAM subsystem.

 

The GPU is used for those things on the GPU Accelerated Effects List such as color work (Lumetri and other effects) and frame resizing (think Warp stabilizer or 4k on a 1080 sequence). The GPU is not used as simply an add-on to the CPU.

 

So for basic playback/rendering, the CPU will use the GPU if ... and when ... it gets to those things that involve GPU accelerated effects.

 

CUDA acceleration is just Nvidia-speak for using their GPUs.

    Thanks a lot Neil. that was what I wanted to hear. so No GPU will be the main processor for the unrendered playback.

      Might want to read this doc on what cuda does and does not do.

      CUDA, OpenCL, Mercury Playback Engine, and Adobe Premiere Pro | Adobe Blog

       

      The cards that are listed have been tested.

      But your 1050 card should work as expected altough 2 gig is rather on the low side.

        Thank You very much. but my main question is that regardless of cuda, the unrendered playback always uses CPU for process ? no matter what GPU is installed ?

        Most stuff is done on the cpu: read the doc.
