Intel ARC GPU not appearing as a second GPU in windows power manager settings

[ImpurestClub]

Hey! I just picked up an A770 to use AV1 encoding and run it in parallel with my RTX 3080.

Unfortunately, the Intel GPU will not show up in power settings stopping me from assigning programs like OBS to it.

If I disable the NVIDIA GPU then the ARC will show up, but the second I re-enable it the option goes away. I tried installing the most recent beta drive to see if it would solve the issue, but it didn't so I rolled back to 31.0.101.4255. I know ARC is supported because if I disable the NVIDIA GPU the system defaults to ARC without issue. I only want to use the GPU as a secondary workhorse to encode and process video.

I'm on the latest version of Windows 10: 19045.2846.

I've attached Intel SSU logs with the 3080 both enabled and disabled as well as a screenshot showing that both GPUs appear in device manager.

try updating your motherboard bios.

It's already up to date.
