720p Netflix on Firefox on Windows takes less than 1% CPU for me, and I'm not sure which process it is, because they're all less than 1% CPU. GPU usage, per Process Explorer, is somewhere between 1% and 7%. The Firefox addon to force 1080p takes it up to about 2% CPU and 9% GPU. Maybe. It's hard to tell, it's usually below that. Basically, it's a rounding error on a machine with properly set up decoding pathways.
