GPU Not Being Used in Premiere Pro and Lightroom Despite Proper Configuration

In video productions, there are so many interlinking interactions between X, Z, and for this use Q, but not P ...  although, if Y then C ... that it can be a bit overwhelming at times.

Understood, these videos are long-GOP (I had to check because I'm a newbie to video editing), even though I would expect that the GPU handles everything.

I thought that was something related to Adobe in general because in Lightroom happens the same, it is slow to navigate between photos (I have a great SSD), or doing HDR merge or even export photos, and never uses the GPU, almost 0% usage in both programs. Something doesn't match.

Thanks for the quick answers.

GPU versus CPU use is a complicated thing. @RjL190365 is our "resident expert" on such things, and might pop in to help.

That AMD chip does not have either the iGPU nor the in-built "hardware" h.264/5 computational bits that some Intel CPUs have. That's a limit on long-GOP work right there.

The GPU has some capabilities, but then ... there's a dance it has to do with the CPU and threading of processing in any particular app.  That's where RJL knows a lot more than most of us.

I run with a 3960x, 24 core Ryzen, with a 2080Ti. Probably going to a newer GPU this winter, but wanting to stay with something with that 11GB of vRAM I've already got.

But I knew I don't work with much long-GOP stuff. Therefore, the Ryzen chip was an option. If I worked with a lot of long-GOP media, I'd never have chosen that chip.

What do you mean by the CPU handles that playback? I cannot even play a video that starts skipping frames, and I have a 12-core CPU—just the video without any effects.

For the export, I tried x264 using hardware encoding, and it throws: "Your system's hardware does not support hardware acceleration for the current setting."

But for x265, it seems that it uses the GPU to encode.

Many render, playback, and export things are handled by the CPU. What GPU acceleratated effects are you using? They do have a list of things the GPU is used for. Specifically.

I'm adding this info in case is needed:
