I have just installed Photo AI on my PC (Intel I9-12900K CPU and Intel Arc A770 GPU, setting the processor to Intel Arc A770 graphics appears to ignore the A770 and run the app on the CPU. Setting the processor to Intel UHD graphics 770 (integrated GPU) uses the integrated graphics on the CPU.
Why is the A770 being ignored in favor of the CPU?
Copy the files from runtime/bin/intel64/Release into the root directory of Topaz. (e.g.: C:\Program Files\Topaz Photo AI)
It should ask you to confirm whether or not you’d like to replace the files. After that everything should work as expected. I still find it strange that benchmark software passmark still works.
