Photoshop not detecting my dedicated GPU on MacBook Pro. Only detects my integrated card.

Question

2017 MacBook Pro with a dedicated AMD Radeon Pro 560, and an integrated Intel HD 630.

All Adobe apps only detect my Intel HD Graphics 630 card. I have automatic graphics switching disabled and activity monitor shows that the high performance card is in use.

Why isn't Photoshop or any other Adobe software detecting and using my AMD Radeon card??? How can I fix this? I have the latest Mojave OS and all of the latest CC apps.

Thanks

Thanks. I realized it was because I'm using an app called Duet Display to use my iPad as an external display. For some reason that disables Adobe apps from using my dedicated GPU. When I turn it off, Adobe software works as intended.

Major bummer, but not Adobe's fault I don't think.

I am not a Mac user, nor even an AMD GPU user, but some stuff to look at while waiting for a proper expert to join the thread

You'd have said if you were using an external GPU, but there might be a clue

With Windows laptops that support an internal Intel HD**** GPU and Nvidea card for high performance, I believe you can go into the Nvidea Control Panel and force the laptop to use the more powerful GPU. Does AMD have a similar feature?
