Hello everyone, my computer runs on Windows 11 and is equipped with an RTX 4090 standalone graphics card as well as a newly purchased Intel DG1 graphics card. To address the issue of hardware encoding for H.265 422 10bit, I tried playing back H.265 422 10bit and other video materials in Premiere Pro 2024 version 24.6.1. However, I found that the Intel standalone graphics card did not work. When I set up in Windows to use only the Intel graphics card in Premiere, the software ran very inefficiently, and playing back a single H.265 422 10bit material was also very laggy. Could you please advise me on how to accurately set up my computer to run Premiere with maximum efficiency?

You got the wrong Intel dGPU for this job. It is a total weakling in terms of overall performance to begin with. In fact, it is heavily hamstrung by its memory throughput that's equal to or less than the system memory! Only 68 GB/s memory throughput for that DG1 versus 76.8 GB/s for ordinary DDR5-4800 system RAM!

Second, it actually predates the Alchemist-generation Intel Xe dGPUs in terms of architecture. As an older architecture, its hardware decoding and encoding is not as performant as newer Intel GPU architectures.
