Thank you for your answer. I have created a new FB9127527 issue with the benchmark and more information inside.

There are links inside FB9127527 to a notarized application for macOS, Windows, and Linux. And multiple simple tests to reproduce the problem on macOS in other FB. Thank you.

This is the same eGPU hardware with 3 times lower performance under Metal: https://gravitymark.tellusim.com/report/?id=bc453e851c5dede3cedef6c3ac9caca2f8dffa47 https://gravitymark.tellusim.com/report/?id=7f1b799adc588938fc02f140a2ee48dbd4f36e69

ICB is working stable with the last OS updates. We have updated our macOS benchmark and released the iOS version: https://apps.apple.com/us/app/gravitymark-gpu-benchmark/id1595186532 ICB is giving a 2.5 performance boost in comparison with the previous version. Thank you for the great improvements.
