Arc B580 + HandBrake 1.9.2: Intel Deep Link not working, iGPU GPU usage stays at 0%

[haobinnan]

Problem Description

Content:
I am using an Intel Arc B580 graphics card and have enabled Intel Deep Link.
However, when using HandBrake 1.9.2 (HandBrake-1.9.2-x86_64-Win_GUI), I found that Intel Deep Link does not seem to work.
Monitoring through Windows Task Manager during video encoding, the iGPU (integrated GPU) utilization stays at 0%, and only the dGPU (discrete GPU) is active.

Environment:

GPU: Intel Arc B580 + Intel UHD 770 (iGPU)

Motherboard: MSI Z790 GAMING PLUS WIFI

OS: Windows 11

HandBrake Version: 1.9.2 (HandBrake-1.9.2-x86_64-Win_GUI)

Intel Graphics Driver: Latest version as of April 2025

Expected behavior:
When Intel Deep Link is enabled, both the iGPU and dGPU should collaborate during encoding.

This isn't unexpected behaviour. HyperEncode only works in specific cases where there is a performance benefit.
Where it isn't, it won't enable.

The capabilities of both GPUs are also different so if using settings that don't align, they won't enable either.

Also, if it's not in full path mode, I don't think it'll activate either. (i.e if anything you have enabled forces HB to use system memory, then it won't enable. For example, filtering)

After updating to the latest Intel graphics driver, everything worked fine. Thanks for your response!
