How to Set Up a Dual PC Streaming Setup for Maximum Performance

by

A dual PC streaming setup ensures smooth gameplay and high-quality streaming by dedicating one PC to gaming and another to encoding the stream. This prevents FPS drops, reduces CPU/GPU strain, and provides a professional streaming experience. This guide will help you set up a dual PC streaming system for Twitch, YouTube, or Facebook Gaming.

1. Understanding How a Dual PC Setup Works

✔️ Gaming PC: Handles all gameplay, ensuring maximum FPS.
✔️ Streaming PC: Captures and encodes the stream, reducing load on the gaming PC.
✔️ Capture Card: Transfers the video signal from the gaming PC to the streaming PC.

💡 A dual PC setup prevents FPS drops and improves stream quality.

2. Choosing the Right Hardware for a Dual PC Setup

✔️ Gaming PC Requirements:

  • High-end GPU (RTX 4070 Ti, RX 7900 XTX) for 1440p/4K gaming.
  • Fast CPU (Intel i7-14700K, Ryzen 7 7800X3D) for high FPS.
  • 16GB-32GB DDR5 RAM for smooth gameplay.

✔️ Streaming PC Requirements:

  • Efficient CPU (Ryzen 5 5600, Intel i5-12600K) for encoding.
  • Mid-range GPU (GTX 1660 Super, RTX 3060) for NVENC encoding.
  • 16GB RAM and a fast NVMe SSD for quick processing.

💡 The streaming PC doesn’t need a high-end GPU but benefits from a strong CPU for encoding.

3. Choosing a High-Quality Capture Card

✔️ Best Internal Capture Cards (PCIe):

  • Elgato 4K60 Pro MK.2 (Best for 4K streaming).
  • AVerMedia Live Gamer 4K (Great alternative).

✔️ Best External Capture Cards (USB):

  • Elgato HD60 X (Best for 1080p 60FPS streaming).
  • Razer Ripsaw HD (Budget-friendly option).

💡 Internal capture cards have lower latency, but external ones are easier to set up.

4. Connecting the Two PCs for Streaming

✔️ Step 1: Connect HDMI Out from Gaming PC → Capture Card HDMI In on Streaming PC.
✔️ Step 2: Use OBS/NVIDIA ShadowPlay to duplicate the gaming screen to the capture card.
✔️ Step 3: On the Streaming PC, open OBS Studio and set the capture card as the video source.
✔️ Step 4: Adjust bitrate and encoding settings for smooth streaming.

💡 Use a second monitor or HDMI splitter for better workflow between PCs.

5. Setting Up Audio for a Dual PC Setup

✔️ Using a USB Audio Interface (Recommended):

  • GoXLR / GoXLR Mini – Best for professional audio mixing.
  • Focusrite Scarlett Solo – Great for XLR microphones.

✔️ Using Virtual Audio Cables (Software Solution):

  • Install VB-Audio VoiceMeeter to send game audio to both PCs.

💡 A USB audio interface allows real-time control over audio levels.

6. Optimizing Streaming Settings in OBS Studio

✔️ Streaming PC (OBS Settings for Best Quality):

  • Encoder: NVIDIA NVENC (If using an NVIDIA GPU).
  • Bitrate: 6000 Kbps (1080p 60FPS) / 8000 Kbps (1440p 60FPS).
  • Keyframe Interval: 2.
  • Preset: Max Quality.

✔️ Recording Settings (For High-Quality VODs):

  • Bitrate: 20,000+ Kbps.
  • Format: MKV (Safer than MP4).

💡 Test different settings based on your internet speed and CPU/GPU power.

7. Using a Network Switch for Faster Data Transfer

✔️ Best Network Setup for Low Latency:

  • Use a 2.5Gbps or Gigabit Ethernet Switch to connect both PCs.
  • Enable NDI (Network Device Interface) for Streaming Without a Capture Card.

💡 A wired connection reduces lag and improves stream stability.

8. Setting Up Stream Deck for Quick Controls

✔️ Best Stream Decks for Dual PC Streaming:

  • Elgato Stream Deck (Best for shortcuts and macros).
  • Loupedeck Live (Alternative with touchscreen controls).

💡 A Stream Deck simplifies scene switching, sound effects, and chat interactions.

9. Optimizing Cooling & Power Management

✔️ Use Airflow-Optimized Cases (Lian Li O11, Fractal Design Meshify 2).
✔️ Upgrade to 750W+ PSU for both PCs to handle streaming loads.
✔️ Monitor Temps with HWMonitor / MSI Afterburner.

💡 Good cooling ensures both PCs run efficiently without overheating.

10. Testing & Going Live

✔️ Run Test Streams:

  • Check gameplay FPS, CPU usage, and network stability.
  • Adjust settings if lag, frame drops, or audio issues occur.

✔️ Monitor Stream Health in OBS & Twitch/YouTube Dashboard.

💡 Test your stream multiple times before broadcasting live to avoid technical issues.

Final Thoughts

A dual PC streaming setup provides higher-quality streams, smoother gameplay, and reduced system strain.

💡 Key Takeaways:
✅ Use a powerful gaming PC and a dedicated streaming PC for best results.
✅ A good capture card and network setup reduce latency.
✅ OBS settings and audio management are crucial for a smooth stream.
✅ Test your setup before going live to ensure stability.
