Thanks for that. That make sense. So it isn't really 2 pass encoding in the traditional sense at all -- it's just 2 passes on a single frame during that frame's encoding.
It looks to me like the new version of NVENCC keeps it in 2-pass-full no matter what setting you specify. I'm sure that's a bug... but probably not a bad one, since 2pass-full is likely the best option in most cases anyhow.
[Edit] I submitted a bug report on GITHUB related to the mode always staying 2pass-full. (or, at least, always reporting 2pass-full)
Interestingly, the encode seems to actually be faster on a UHD source on v5.10 vs. v5.09 -- even with 2pass-full always selected. I'm not sure that that might mean.
