That page runs at 2 fps on my Firefox, windows laptop with A2000 graphic card.

hmm not sure, I was lucky enough to stumble upon the page during the short window it was live and just saved it without any changes.

does it run better on chrome perhaps? i also have a pdf version if that's nicer: https://drive.google.com/file/d/1BO-LIAUcQevx7j1AiLhzJiVDeVX...
