While performance might be improved, as the app is in beta there are a lot of tools missing. Native versions of Photoshop for both Windows and macOS should greatly improve performance, just in time for Apple to release its first Arm-powered Macs. Currently, Photoshop runs emulated on Windows on ARM, or through Apple’s Rosetta translation on macOS.
The beta releases will allow owners of a Surface Pro X or Apple’s new M1-powered MacBook Pro, MacBook Air, and Mac mini to run Photoshop natively on their devices.
Adobe is releasing Arm versions of Photoshop for Windows and macOS today.
