Some suggestions:
05:56:56.331: YUV mode: 709/Full
Change to 709/Partial. The full color setting is not default and is increasing load and decreasing quality for your recordings.
Introduction. For higher compression rate, video encoders usually use methods of representation of each video frame as 3 separate channels: one for luminosity and two for color. This allow to compress color info separately from the luminance...

05:58:13.230: [NVENC encoder: 'recording_h264'] settings:
05:58:13.230: rate_control: CBR
05:58:13.230: bitrate: 20000
Don't use CBR rate control for NVENC local recordings. Use CQP rate control, and a quality setting. The lower the quality number, the higher the quality. 14 is very good, 23 is good. Set at a number that gives you smooth performance.
06:02:45.128: Output 'adv_file_output': Number of lagged frames due to rendering lag/stalls: 14 (0.3%)
Slight rendering lag. That's GPU overload.

This is in your x264 encoding attempt, which indicates you are overloading your CPU attempting 1080p60 at veryfast. You can try a faster preset, or target 720p60 or 1080p30 instead. With x264, use CRF rate control and a quality setting on the same scale as CQP for NVENC.
With CRF option it stutters even more than before.
Thats the another attempt,after setting cpu to superfast
