Everything is described in the original post. The main problem is performance because even a loop of draw indirect is faster than an indirect command buffer: https://www.icloud.com/iclouddrive/0ICuhBkHgGuLjCxaJwRyHoLmw#execute_commands_in_buffer https://www.icloud.com/iclouddrive/0hDo_q0oXs4uzC25yZdKmL83A#multiple_draw_indirect I made Feedback Assistant more than half of year ago. There was no answer. After that, I wrote here. Thank you!

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.
