I get the appeal of this stuff from an aesthetic perspective, but it's woeful from an accessibility standpoint and it makes your website completely unusable on older computers and not-that-old mobile devices.
Cool, but use with caution. The usual warning for graphics-heavy web stuff.

I agree with the sentiment and generally advocate for lighter and simpler webpages, but the 3D animations on this particular landing page were perfectly smooth on my 12 year old macbook. I was impressed, since these kinds of heavy animations usually run like crap for me.
I have a small pile of Android phones of various ages and price brackets (gotta test stuff, y'know). Throw in heaps of Thinkpads of a certain vintage. IME, it's the age of the software that predicts browser performance much better than hardware. A 6-year old flagship phone that's stuck on Android 8 is a hot mess, while another one of the same age and similar specs on Android 10 runs great. Not sure why, but it's a consistent pattern across all these devices.
