HEVC Playback not using GPU - Stuttering

Hi,

I have a GTX 1060, Premiere is set up to use GPU Acceleration (CUDA) in Project Settings.

When I try to playback a HEVC HDR MP4 file, I get stuttering. In task manager I can clearly see the CPU being used only (Only around 80%). GPU is not. However I get really bad stuttering.

If I use MPC-HC, the same video plays back perfectly and Task Manager shows the GPU is in use.

This is the video in question. I'd like to know if this plays back fine for anyone in Premiere. Is this an Adobe issue?

Within this NLE, that de-encoding/de-compression for basic playback is near totally a CPU cores/threads/RAM issue. This is long-GOP media, which is some of the nastiest stuff ever made for de-encoding on a computer anyway. It's great for compressing camera data to small amounts with specialized chips on the camera for fast card writing, and for uploading/downloading over the web. Horrid for editing.

Highly recommended to use PrPro's create proxy on ingestion process, using the included Cineform presets. Drag the proxy toggle icon control to your program manager controls, and toggle proxies on (blue) for playback, off (grey) for checking quality while stopped/paused.

I recommend using Cineform proxies (or possibly even Transcodes) for this media.

Thanks guys, I figured this was it. As long as it just wasn't my set up.
