This question is 7 years old. (question on SO)

As far as I know, the only effective way to youtube speedup is

1. Mobile version m.youtube.com
2. Alternative mirrors like Invidious
3. Applying some experimental flags

3.2 https://greasyfork.org/en/scripts/431573-youtube-cpu-tamer-by-animationframe

4 Redirecting video to local players using like youtube-dl libraries

4.1 #1

4.2 #2

You can look for magic scripts if you believe in magic - https://greasyfork.org/en/scripts?q=cpu+youtube

The script you provided is lazy loading of some elements. In principle, YouTube is now taking a similar approach.

It is possible to revive this script, the problem is that it is useless
