The temporal values cause trails.  Set those low.

Can't say I've _ever_ seen that, though I've never combined the two.

Then use "turbo".

That doesn't make much sense.  Figure out what the average bitrate is
when you encode the video with your CRF values, then use that as the
bitrate for a 2-pass encode, and you should get somewhat better quality,
 at the same file size.

With the way x264 handles threading, I wouldn't be surprised if
2-pass+turbo mode was just as fast as CRF, on systems with several
cores.
