Mine doesn't stutter on on Firefox on M1 Max, but it pins 7 cores the entire time the page is open, not just while loading. It also uses 50% of GPU in addition to that.

Edit: The argon built site pins 1.3 cpu cores. The Sol 6.1 site uses 0.18 cores.

Unless it is something with the playback on my end, your animations and scrolling are a bit jerky too.
