Welcome to Duo - your one-stop solution for easy, headless, Windows-based game streaming & multi-seating.
If you've ever operated a GeForce Experience GameStream or Sunshine host, you'll be painfully aware of what this entails:
- You can't use your computer while you're streaming from it.
- Your computer must always be connected to a monitor, HDMI dongle, or an indirect display driver for the stream to function.
- Streaming to different clients at varying resolutions, refresh rates, or color spaces requires several helper tools to enable, disable, or alter monitor configurations.
- Only one person can stream from a given computer at a given time.
Duo does away with all of these issues by giving each user their own independent Desktop, essentially allowing multiple people to play games on a single computer at the same time without getting in each other's way.
- One free Duo instance (in addition to the host's physical session, capped at 30Hz)
- Automatic display adjustments based on the Moonlight client's settings (on Windows 11 23H2 or newer)
- Built-in support for user-configurable super-sampling
- Built-in support for multiple Steam instances
The following benefits can be unlocked by logging in with a Patreon account that has contributed a total of $10 or more to my campaign over its lifetime or a Ko-Fi account with enabled Duo Supporter Benefits:
- Allows you to run as many Duo instances as your hardware can handle (in addition to the host's physical session)
- Unlocks refresh rates up to 500Hz (limited only by what your hardware encoder can handle)
- Unlocks HDR support (on Windows 11 23H2 or newer)
- Unlocks Sandbox support (temporarily unavailable)
