Poor performance on iMac M1

Hello.

I used C1 21 on an iMac 27 (2020) and it worked good but the crop&rotation tool were not very smoothly.

Then I switched to the 13'' MacBook Pro with M1 processor and the native version of C1 ran flawlessly. The experience was much smoother than on the big Mac. So I thought that on the new iMac with M1 chip the program would run as smooth as on the laptop but it's not the case. The rotation tool is very-very slow and laggy, and the overall program it feels a bit chunky to use.

I tried to modify the previews to 5120, 3840, 2880 and the results are the same. It's obvious that the problem is related to the big resolution screen but I'm sad that C1 team didn't resolve this. In contrast, Lightroom is performing amazingly but unfortunately the image quality in Lr is not quite as good as in C1.

If anyone had find a workaround to making C1 run smoothly on iMac M1, please reply. :)

Have a great day!

similar problems i faced with an imac 24 inch / M1 chip.

performance was not acceptable and since i wrote to the support of C1 and for 18 days the support never replied to my open case, and apple support could also not help me to solve the problem i gave the newly bought iMac back :-( to the store and got a refund.

very disappointed and shocked by the way C1 support ignores problems of their customers.

wish u luck with your machine ..
