They're nice and smooth on my Ryzen 5 4500U/Vega 6 with 8GB of RAM. Of course the 5 seconds of artsy chaos spinner each of them has on load is still absurd. But it's fine after that. Could it be the browser? I loaded them in Firefox.

No idea, I tried them on both firefox and chrome and things were pretty laggy. Some worse than others. I don't have problems scrolling on other sites.
