Improved streaming quality and connection stability for an app like this can actually be pretty meaningful, so I figured it was worth sharing.
The open-source community made PlayStation Remote Play app Chiaki-ng v1.10.0 has rolled out, making it even better to stream games to other systems.
Does it support party chat, or microphones?
I believe so, but the mic is muted by default. You can set a back button to ctrl+m to toggle the mute I believe.
