Photoshop Elements 2021.2 Update has been released today!

Michel, obviously there is no update to ACR, and I'm still seeing some hesitation in the ACR crop tool.  IIRC, there were some other performance issues that you were seeing with the preview of certain tools.  Are you seeing any improvement in those?

Greg,

I have not seen noticeable changes in the way some sliders in adjusting boxes don't show the changes in real time but only when I release the cursor. I would need to make more comparisons with previous versions.

What seems more responsive is the switch from detailed view to adaptative view in the organizer. Looking at the task bar, it seems that there is some influence from the GPU and a distinct one from the processor. It's a first impresion to check with comparisons with older versions.

With the same computer, the ACR 13.2 in Photoshop shows very fast and smooth sliders action, which shows in the task bar panel in the GPU usage.
