Photo AI 2.3.2 using integrated rather than discrete GPU

Steps to reproduce issue:

  1. Step 1
    Open image in Photo AI

  2. Step 2
    Make cup of tea whilst waiting for inegrated GPU to process the image rather than the discrete GPU having the job done in a fraction of the time.

  3. Step 3
    There is no step 3.

Doesn’t make any difference whether Auto or AMD Radeon Pro 5500M is selected as the AI Processor. The integrated GPU is slower than selecting the CPU.

Have confirmed the integrated GPU is being used with the Intel Power Gadget and iStat Menus…
CPU frequency, CPU load, Radeon Power and Radeon Utilisation remain low whilst processing images. Intel Power Gadget shows GFX frequency pinned at ~1.2GHz.
