I don't think my computer even does HA, so that's about as far as I can go .

Maybe PM doesn't support HA for VP9?
Maybe there is an about:config switch that might enable it?
There could be [graphics card] blacklisting going on?)


Well I'll be. (Don't think I've ever seen it before, but...)
I see the opposite.
PM is using HA on VP9, FF 115 is NOT.

Win7, Intel HD Graphics 4000 (on CPU)


I'm only seeing VP9 on that page.
How were you forcing (or were you) AVC?


In FF, initially HA was disabled, but after enabling it (but not restarting if that matters) [about:preferences -> Performance -> Use HA when available] there was no change. [New FF Profile, that setting enabled & restarted, still no HA in FF.]

(I most likely manually disabled HA in FF due to a crash?)

Pale Moon most definitely does hardware decoding. Playing that costa rica video at 4k resolution loads the GPU, not CPU. Note that video decoding may happen in the "3D" classification as well if it uses shaders, and not necessarily under "Video decode"
