If you’re looking for a solution to stream PC games to your mobile devices, give Moonlight Game Streaming a try. The app uses a GameStream-compatible PC and allows you to stream PC games, full desktops, and different programs.
Below is a brief video showing how the app works flawlessly.
You can add any other apps to this list through GeForce Experience or stream the full desktop. Mouse, keyboard, and controller input is sent from your Android device to the PC.
To have a good experience, you need a mid to high-end wireless router with a good wireless connection to your Android device (5 GHz highly recommended) and a good connection from your PC to your router (Ethernet highly recommended).
The App is available on both iOS and Android.
Advanced setting details and how to set things up is explained here.
On the other hand, if you’re looking to stream PS4 games on PC, Sony has announced that it is working on an official app. However, if you can’t wait for Sony, a certain paid app is the way to go.
