Photoshop 2021: Panning and zooming are REALLY slow with update
I've 'purged all', optimized all the performance settings, freed up lots of space on my SSD and still PS is dragging and sputtering. I use a track pad and a mouse with wheel and the option key for zooming and I get blank-out's and frozen pixilation and crunchy artifacts that go away temporarily when I close and re-open an image.
All the Activity Monitor tabs show easy workloads EXCEPT the drive which has twice the headroom as before when all worked smoothly.
What am I missing?
