I'm not sure if this was just me but I just wanted to write somewhere that you need to enable Virtual Audio if you intend to use Shadowplay's video record functions. At least on my PC; without it Shadowplay does open but can only screenshot and cannot record.
I spent an hour enabling and disabling different components with DDU until I found out that recording works again if Virtual Audio alongside Geforce Experience + It's requirements + Shadowplay is enabled to get recording working.
