That scaling isn't done on the CPU, so any CPU load issues are not related to that.
You can use e.g. -vf dsize to control more accurately the size to use for display, e.g. selecting 1920x1080 as resolution (I don't know the exact command out of my head, hopefully you can figure it out from the documentation).
Though since you run in fullscreen mode, the real resolution should be whatever your screen uses anyway, so probably it doesn't matter.
If the CPU s indeed the issue, have you enabled multithreaded decoding? (-lavdopts threads=6)?
Also why not use hardware decoding (-vc ffh264vdpau,)

It should make only a minimal difference, unless you are vsync limited (which I admit you probably are if you try to play 60fps content on a normal TV).
