Preview rendering not using dedicated GPU?

[viveredesign]

With the latest update, as Adobe trumpeted, I see that my relatively powerful dedicated GPU (RTX 2060) utilization is now ~75% upon final render, but sadly any preview work (auto or forced/manual) is using ONLY the weak integrated motherboard GPU (~80% utilization). I've poked around but could not change this.

Is this what others have observed?

It's odd that Adobe chose to improve final/output render since that can be scheduled/delayed, while the in-app live-human interface should obviously have been the priority to improve rendering performance.

Avid is looking much more attractive. Photoshop is excellent, but Adobe seems not to care about all the other apps they've rapaciously bought up over the years. It seems that the real money now comes from collecting/selling people's private information.

Please post your:
Computer specs/setup,
Operating system build (not just the latest).
Premiere exact build (see about),
Mediainfo screenshot in treeview of media used.
Export setting and with left tab to output.

Here's why:

Premiere does not currently support NVDEC at this time. NVDEC support is required for the previews of H.264 and HEVC to utilize the discrete Nvidia GPU for playback.

As for the utilization of the integrated Intel GPU, Premiere has already been supporting QuickSync (which is an Intel exclusive) for decoding, at least since the days of CC 2015. If the Intel GPU were to be disabled (or you have a CPU that does not have an Intel iGPU integrated), then previews would have been entirely on the CPU.

Thank you for that direct and insightful technical answer. I and others can stop trying to tweak our systems to "make it work."
