How Multiplicity 4 is Used

Gaming

Streaming your games online is a popular way to share your content but streaming setups are complex and require high-end hardware to make it all possible. With Multiplicity, you can offload non-essential apps like Discord or OBS/xSplit to other devices but still access them from your gaming box.

Free up resources by running apps on other devices so your primary box is only gaming.
Stream audio like voice chat across your network.
Use a spare laptop as a second (or third) monitor to expand your streaming space.

Editing

Content creators know the challenges of slicing together complex video and audio files and the large workstations required to export the video quickly. With Multiplicity, you can put your editing rig, with its loud and noisy GPUs and fans, in another room and edit on a laptop by streaming the desktop to your PC.

Stream a desktop to any other PC and let your laptop tap into the full power of your editing PC while you work in another room avoiding the loud noise of your GPU.
Share audio across devices for creative podcast hosting from within the same location without using the Internet.
Hotkeys make it easy to jump between workloads to help you export faster.

Development

Running Visual Studio or your favorite IDE and streaming it to your minimalist setup is possible with Multiplicity. Put your powerful and loud dev box in another room and stream the desktop to your laptop and get the best of both worlds, fast compilation and whisper quiet operation.

Easily switch between desktops with Multiplicity so that you can quickly test your app in multiple versions of Windows.
Put your IDE on another box and stream it to your preferred PC.
