Photoshop 2017 chooses wrong GPU

[Guest]

Hi. I have two GPU's in my computer: AMD RX480 and Intel HD4600. To both GPUs connected displays. In Windows settings display, connected to RX480 selected as main screen. HD4600 run as "passive" mode. Photoshop see HD4600 as first GPU and try use it, but can't do it because that GPU in "passive" mode.

If I disable HD4600, Photoshop see only RX480 and use it successful.

If I set HD4600 as primary GPU, Photoshop can use it, because it active.

Any changes to the settings in the BIOS do not give results.

How turn on GPU acceleration with RX480 as primary and HD4600 as secondary?

Hi

Photoshop is designed to work with one GPU. See this link - in particular section 7.

I saw this page. But in last driver version I haven't this option.
