Where are you actually having issues? Your logs stop right after the report of a 4 second recording test... not a lot to go off of.
You're already using NVENC, which is going to be the most performance-friendly option, especially when talking about 1080p capture.
You do have Game DVR on, which can have an effect on performance. Turn it off.
Display capture is relatively slow compared to game capture, but I have no idea what you're capturing so I can't say whether that would be usable in your situation.
