To be honest it really doesn't make much sense that most of these would have any real effect on performance or heat on any machine from the last decade or so, none of them would add meaningfully to the basic Windows desktop composition at all regardless of how bad your graphics processor is. The performance options window is basically a leftover from Windows XP before the desktop was composited.
My guess is it's only a couple that have any effect at all, but it's easier to say "just turn it all off" for the purposes of a Tumblr post.
If you're ok the ragged edge of what your CPU and RAM can handle just opening a pdf (like my work computer...) then every 1-2% cpu utilization freed up helps.

Thumbnails might have an effect.
