Hi,

EDIT: (new settings)

here my low cpu usage settings for "strict" streaming ~5000kbps 720p60
its a baseline/high/(very)faster-chimera

x264 Options:
level=3.2 no-cabac=1 ref=1 bframes=0 direct=spatial deblock=-3:2 no-mbtree=1 me=umh subme=2 sync-lookahead=0 rc-lookahead=0 trellis=0 weightp=0 aq-mode=1 aq-strength=1.20 threads=3

with Ryzen 2600X @4.2GHz i have 10-15% load
here you can see a test: http://youtu.be/kamEtzFPMR4

Btw, you can remove the "deblock=1:1" from the commandline, as "tune=animation" allready sets it to that by default
"direct=spartial" should be "direct=spatial"
If I may add, "aq-strength=1.3" can help with blockyness, and can probably help you reduce bitrate about 500kbps without much more load on the CPU

@Zidakuh
you are wrong about "tune" reseting x264 options - those custom options overwrite all presets etc;
but i will try "aq-strength=1.3" today
