In addition to other complaints about x265, I still can't comprehend why deblock 0:0 is default like in x264, this singular setting is the biggest reason a lot of encodes, including broadcast, look so blurry. I would rather have a little bit of macroblocking than the picture turn into complete pudding. Yeah yeah you encode blu-rays as your profession at a gigazillion bytes per second, that's only a very small fraction of what video is compressed. Personally I use -2:-3 at crf 22-24 but even a -1:-1 already gives a massive improvement.

Here is the lossless and the 'slow no-sao deblock' full frame versions. I think the results are very impressive for 6Mbps!
Tried another frame as well, this time a "harder" one. It seems like turning off strong intra smoothing hits efficiency pretty hard, in this frame it creates some heavy blocking.
