Control GPU Performance with script?

[rcraighead]

AI 2020 GPU Performance is not fully compatible with 2015 iMacs. In some workflows it is fine and offers great advantages. In others it causes UI glitches and/or crashes.

As a workaround, I've tried turning Preview to "GPU" or "CPU" depending on the workflow. Did not fix the crash issue. Now I would like to turn "GPU Performance" on or off depending on the workflow.

• Can preferences be controlled using Javascript?
• If not, can GPU Performance be controlled by an AI Action? I've tried without success.

my preference in CC2021 is v19, I was expecting something more general, you'll have to check what version you have in your prefs file

to disable gpu

app.preferences.setIntegerPreference ("Performance/EnableGPU_Ver19_2",0); // 1-checked, 0-unchecked

Thanks @CarlosCanto ! How do you know all this? 🙂

"v19" worked in 2020 as well. How do I determin what Version# a preference is?
