Photoshop can't activate the Metal mode, although all parts of the GPU are recognised and switched on in the preferences. There is usually just »legacy openGL« or - even worse - only CPU mode.
- latest PSD version (24.7.0)
- latest Mac OS (Ventura 13.5)
- enough RAM
- native canvas disabled (because of an other bug)
Interesting to know: PSD Beta is working in Metal mode.
