Don't assume that the very first check-in of a new feature includes full optimization or full quality tuning. x265 has gotten a
lot better
and a
lot faster over the last 18 months!
For something as far along as x265, having any single new feature that offers an obvious visual quality improvement is a huge accomplishment. x264 hasn't had one of those since, sheesh, mbtree? Most codec development is about squeezing out a bunch of discreet <<1% compression efficiency gains.
