Photoshop 2023 won't use dedicated GPU when "Auto Show The Home Screen" is disabled.

[Guest]

When "Auto Show The Home Screen" is enabled (selected) in Preferences/General, Photoshop 2023 will use dedicated Nvidia GPU.

When "Auto Show The Home Screen" is disabled (unselected) in Preferences/General, Photoshop 2023 will NOT use dedicated Nvidia GPU.
Any help appreciated.

Thanks!

It sounds like you have a laptop with dual GPUs. GPU conflicts is a known potential problem.

You may need to disable the integrated GPU completely. See section 6 & 7 here:

In addition to D.Fosse's helpful reply here's some helpful links I saved for anyone with GPU issues

Here are some suggestions from Adobe for GPU issues.

First check the system requirements: https://helpx.adobe.com/photoshop/system-requirements.html
