https://indigoengine.io/pirate.html performance is abysmal on Safari 16.3 and macOs 13.2.1. The oddity is that the framerate is being reported as 30-31fps.
Are you perhaps in energy saving mode? I get 60fps on a M1 laptop.
On Safari?
Interesting, I'm hosting https://scalajs-games.wiringbits.net and some users reported poor performance on Safari, still, I never dig into it, I wonder if you experience the same.
Quite interesting how people are downvoting that when it is the reality, the game is a slideshow, it reports 30fps but might effectively run at 1 or 2 fps on my M1.
