This question is NOT:
How to know if Firefox uses hardware acceleration?
The question rather focuses on, when it does switch from CPU to HW acceleration, if it does so with my dedicated card or with the integrated card (and how to check that).
How to make the whole and complete runtime of Firefox use my dedicated card?
(Which is usually done in the GPU's control panel by setting the executable to it.)
This question is rather about the ability for a browser to switch from CPU to hardware accelerated and in that ability I am asking if it also uses my dedicated card for it and if so, how can I make sure for myself?
I have checked my taskbar icon from nvidia when playing the xwing game, but it doesn't show anything (says it's not using dedicated). However that icon may just show if the complete program is using the nvidia card (as in the second "NOT" question above) and not just the canvas or whatever it is.
If this question cannot be answered for all dedicated cards, I guess one for NVIDIA card only is appropriate.
Edit: this question is about a laptop if it was not clear, where it's standard to internally "switch" from integrated to dedicated and vice versa.
