Desktop Vision supports gamepad emulation on Windows 10.
Once you've got the Desktop Vision streamer app installed, and the accompanying gamepad emulation driver called ViGEmBus, you'll be able to play your pc games on a smartphone with touch gamepad controls, or a bluetooth gamepad. Your games can be streamed in up to 4K resolution at 60fps (only limited by your internet speeds and your computer's processing power). You can also opt for a lower resolution and lower latency streaming mode.
