After NVidia's cancellation of GameStream, I'm switching to Sunshine, an open source implementation of GameStream which works with any GPU and (much too my surprise) as low or lower latency as GameStream.
So... NVStreamer has to follow.
Be warned, this release is not the best way to do it, but I wanted to make the switch quickly.
What it does, is stop all instances of Sunshine, than star up its own instance so that it can check Sunshine's output for client connect/disconnect messages.
That means that unfortunately... NVStreamer1080 now needs admin rights in order to stop the service and let Sunshine run with top GPU priority.
The Sunshine integration is only active when you run it as admin and fill out the "Path to Sunshine" box. If you don't it will work as before, namely watching for NVStreamer processes, but you won't be able to use Sunshine.
Have fun ^^
