Zero-FPS Penalty Broadcast Performance
Separating your gaming PC from your encoding streaming PC ensures 100% of your primary rig's CPU and GPU power goes into high-framerate gameplay.
1. HDMI 2.1 Passthrough (4K120 & 1440p240 VRR)
PCIe capture cards with HDMI 2.1 (like Elgato 4K Pro or AverMedia Live Gamer 4K 2.1) allow playing at 4K 120Hz or 1440p 240Hz with G-Sync/FreeSync VRR enabled on your gaming monitor while capturing 1080p60/4K60 for OBS.
2. Audio Routing (Voicemeeter Banana vs. Hardware Mixer)
Route in-game audio, Discord voice, and microphone input between both PCs using optical TOSLINK cables or Voicemeeter VBAN over local Ethernet.
