Dual PC Streaming Setup

A dual-PC streaming setup separates gameplay from encoding so each machine can focus on one job well. The result is smoother gameplay, more stable streams, and more room to build a serious production setup as your channel grows.

What You'll Need

Hardware

• Gaming PC – Runs your game, graphics workload, and player input.
• Streaming PC – Handles encoding, overlays, scenes, and platform output.
• Capture Card – Devices like the Elgato HD60 X or AVerMedia Live Gamer 4K send video from the gaming PC to the streaming PC.
• Audio Interface or Mixer – Optional, but helpful for routing and balancing audio across both systems.
• Headset or mic splitters / USB mixers – Helpful when you need cleaner audio routing between both PCs.
• Ethernet connection – Keeps transfer and network performance stable across both systems.

Setup Steps

• Connect Capture Card
  • Connect the HDMI output from your gaming PC's GPU to the HDMI input on the capture card.
  • Then connect the capture card to the streaming PC with USB.
  • Install any required drivers or companion software on the streaming PC.
• Configure OBS on Streaming PC
  • Install and configure OBS Studio or Streamlabs Desktop on the streaming PC.
  • Add a Video Capture Device source for the connected capture card.
  • Adjust resolution, bitrate, and frame rate settings to match the quality you want to ship.
• Manage Audio Properly

  Most creators use one of these two audio-routing approaches:

  • Option A: Using an Audio Mixer (Best)
    • Combine your mic, game, and chat audio into one source and feed it into OBS on the streaming PC.
    • Popular options include GoXLR, Behringer Xenyx, or virtual tools like Voicemeeter Banana.
  • Option B: Using a Virtual Audio Cable or USB Splitter
    • Split microphone audio so both PCs can use it.
    • Use tools like Voicemeeter or VB-Audio Cable to route audio digitally.
    • Be sure to disable audio monitoring in OBS to avoid echo loops.

Tips for a Smooth Setup

• Sync audio with OBS's sync offset if your voice and gameplay do not line up.
• Use Replay Buffer on the streaming PC to save highlight moments without extra strain on the gaming PC.
• Keep both PCs grounded to avoid static and electrical interference.
• Optimize bitrate and encoding on the streaming PC for the best quality, whether you use NVENC or x264.
