- --tskip
- --cu-lossless
I've fond some value in very low bitrates or unusual content from all but the higher subme and me, which I've not tried.
--me sea in particular cuts speed enormously.
Tskip and cu-lossless can help with anime, small text, screen captures, and other stuff with sharp detailed edges.

Is --subme tied to RDO in the way that it is in x264?
In x264, --subme 6 upwards have increased levels of RDO. But seems that RDO is its own separate thing in x265 with RD levels 1-6 and rd-refine being a separate switch too.
