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?
According to your description, it seems like you’re using Windows 10.
Unfortunately (?), you’ll most probably need upgrading to Windows 11 to precisely select the GPU you desire to use, as both GPUs you’ve installed are dedicated ones.
Detail: Windows 10 Version 22H2 (build 19045) and below does not have this feature, as such feature first appeared in Windows 10 Insider Preview build 20190 which has now expired.
