GPU-P is a pita to keep updated and is half baked. So many things just don't see or use the Nvidia drivers properly. If you want 60fps, Parsec is the only solution I found for desktop/mobile Nvidia graphics.
Once I discovered that, I haven't looked at parsec. Moonlight/sunshine (whatever the pair is) is... terrible. And, When I was looking YUV444 wasn't a feature. Or, at least not one anybody actually knew how to use.
