Yes it would. And just so you know... im in the same boat. Having a terrible time getting this mix to blend smoothly. What seem to be the issue is that OBS cant use x264 with descent settings without hammering the entire system down. I can not even do very fast with 3500kbps smoothly, im forced to use NVENC.
But then on the other hand, i can use Plays.tv with 10 000kbps 60fps 1080p with only a minor performance impact..
So im really out of clues. However NVENC works pretty well. Tho you have to bump up bitrate alot for it to be watchable.
