Most of the things on the internet relate to laptop users wanting to force firefox to use integrated graphics. I have a 3070ti and a 1660S and I want firefox to only use the 1660S for processing.
I have set the 1660S as the opengl renderer in nvidia settings and that changed nothing.
I've tried to disable primary gpu in device manager, then open firefox, then re-enable primary GPU and while that does make firefox switch the gpu in about:support it ends up crashing webgl and not really functioning correctly.
I've tried to change the power management settings in graphics settings and it still uses the 3070 as the primary.
any ideas?
this is the power management settings that i've already tried. it changed nothing.
