You don't have specified the version of NVEnc used. This is the full output of NVEnc on my PC
In my case is the version 5.42. Your Card is quite new and probably is managed better with the last version:
https://github.com/rigaya/NVEnc/releases....42_x64.7z
Also I suggest to don't use 2-pass encoding but the "constant quantizier" (with CQP I:20 P:22 B:25) as shown in my previous screenshots.
You get constant quality across the frames and it is a little faster.
