Just installed PS version 22.4; tried to run 3D but failed because "USE GRAPICS PROCESSOR" was greyed out. Relaunched PS "USE GRAPHICS PROCESSOR" tick box OK, started 3D - Greyed out. Everything worked on version 22.3.1 - what's changed. I need the 3D capability!
This update is suppose to fix issues people were having with version 22.3.1 and GPU's not been recognised, looks like it had the opposite effect on you, you could try a preference reset to see if that helps
Specifically, we recommend using theTech Previewoption for overriding Photoshop’s native canvas mode to continue to use the 3D features. Go toPreferences > Technology Previews, and check the item Deactivate Native Canvas, then restart Photoshop.
