Force use of iGPU on a Mac

[Piotr Bialecki]

Hey graphics-dev!

Is there a Chrome parameter that'd force us to use iGPU on a MacBook Pro? I see that in my case the dGPU is being picked up consistently (I've disconnected external monitors and the device uses battery now, but that does not seem to change which GPU gets selected). I've tried passing `--force_low_power_gpu`, but that also does not seem to help, chrome://gpu still lists GPU0 (AMD Radeon) as being active (screenshot below).

Am I missing something here? Is the parameter expected to work, or am I holding it wrong?

Thanks,

-Piotr

There might be other flags too, but you can try the --force_low_power_gpu=1 flag which should force the integrated GPU on Mac.

D'oh, thanks, it seems to work! I did not realize that there's a difference between `--force_low_power_gpu` and `--force_low_power_gpu=1`.
