It’s almost like 3d rendering is vertices and shading is an embarrassingly parallel problem which is quite trivial to make faster by throwing more hardware at it.
General layouting/text rendering, etc are not like that, and there is not even a “free” improvement anymore with single-threaded CPU speeds plateauing.
Yes, modern computers are just too slow to handle layouting a facebook page, nothing can be done.
Do you have any form of proof that layouting is a bottleneck anywhere?
You were the one who said that layouting is much harder problem then 3d rendering...
It is a much harder problem, but it is working just fine on even low-end mobile phones with the majority of websites.
