--- Comment #2 from Mike Wyrzykowski <mwyrzykowski at apple.com> ---
This was due to running with the Metal debug validation layer enabled. With it disabled, framerate says ~18ms which is comparable to Chrome.

Caching state calls brings the time with debug validation layer enabled down to ~115ms, might be worthwhile to cache the state calls ourselves to make analyzing the gputrace files easier.
