I ran it on my Pixel 7A and even the ray tracing demos ran insanely quickly. I seriously did not expect that.

Maybe the author tests it on some old device with outdated graphics driver, because they all run smoothly on my 5 yo Android.

Chiming in with my Samsung J3 2016, it ran pretty well here too

On Safari iPad, I lose the ability to scroll or do anything somewhere in the middle of the article.

Huh, I read the whole article and interacted with all the inline examples on my iPhone SE/2.

It's butter on my M1 Air too, in Chrome and Firefox. Surprisingly, it's a slideshow on Safari.

M4 iPad Pro here started to freeze up on the Starry Night animation.

iPad 13 Pro as well.

For me it's not that it's freezing, it's that the page scroll stops responding.

I can get the tab back by cutting the URL, closing the tab, opening a new tab, pasting the URL, then scrolling to where I want to keep reading from.

It seems to render everything fine if you don't mind scroll stopping (ahem).

Weird. I'm on a 2011 Lenovo desktop with an i5 and it ran smooth as butter.

Probably Safari is at fault.

Yeah it was a slideshow in Safari on Mac, butter smooth in Chrome

All the examples were good on my Samsung S22 Ultra too, really cool.

Even on a 7 year old first gen AMD, it's smooth as butter. Looks like Stylo and Webrender doing a great job?

Firefox on an m2 has taken the news of these bouncing balls extremely poorly

Worked very well on my Pixel 7 in Chrome too

M1 Pro here and it ran completely fine.

That's weird because it completely freezes m2 ipad
