please guys we need this |

I've been excited about this since it was first mentioned after the GeForce Stream Host closure announcement. I hope it's added soon! |
I would keep the expectations in check. The existing code barely skims the surface of the problem and doesn't touch the most annoying part of it, which is the virtual driver. As far as I'm aware nobody's currently working on finishing it. |

Ok @ns6089 do it. Use this as a scaffold and do it. I'm busy with other projects. Friends of mine brought this issue to my attention. Or you can give me another two weeks and I can get back it eventually in mid-oct |
