Performance Problems with 16.4.3.15 on M1 Mac

Is anyone else experiencing massive performance problems on M1 Mac, too? I just updated today from 16.4.2 and now C1 is almost unusable. Changing e.g. saturation on a raw file takes about 5 to 10 seconds till the picture updates. Exporting to jpeg - handled within a snap in the background before - now takes up to 40 seconds while nothing seems to happen except that a .tmp file is created within the target folder, and the program reacts even slower.

I am working in a session with a folder of about 190 pictures, Nikon Raw files (45MP), nothing special, and I am in a bit of a hurry as I have to develop the wedding pics in time...

And yes, I restarted C1 and also the whole computer...

  Rebuilding the image core kernels as described here helped a little bit, but the solution was to disable hardware acceleration within the preferences.

  I don't know why, but after disabling hardwar acceleration the images are developed within a fraction of a second...

  I have performance problems too (I admit I have an older mac, the last Intel MacBook 16", but I don't think that the delays I'm seeing are normal), and disabling the hardware acceleration doesn't help. BTW, disabling hardware acceleration for a graphic editing application is a nonsense — I think C1 has serious problems in this area.

  Also unusable here on a Macbook Pro M2 Max. When i close the application and opoen again it takes like 1Minute. Downgraded now to 16.3.8.
  Copied all pictures to a new session and its fast like always again.

  In my personal experience, it also worked perfectly and didn't have any major issues with as much shooting frequency as I was working.

  Perhaps related. I've recently started seeing delays when editing; sometimes when I adjust a parameter it takes a while before Capture One responds, five to ten seconds sounds about right. I don't remember seeing this before. I also use an M1 Mac (Max 64GB).

  I've just started having issues with CO 16.3 and 16.4 not renaming the files or deleting them from disk. Import is slow also.  I'm using an M1 Mac Studio with Sonoma
