Encoding stops unless AME is run in Rosetta mode

So I just got a Mac Studio M1 Max. Yesterday I was rendering a 90 seconds clip from AE but noticed after just a few frames of rendering that the processors performance meters just dropped from full to very moderate.

I retried a few times, but the file just wouldn't export. The issue was resolved by setting AME to run in Rosetta 2. 

I was rendering with h.264 and the High Quality 4k-preset. 

Running Monterey. Everything is updated to the latest version according to Creative Cloud.
