10 Mbps Upload: What You Can Realistically Achieve
At 10 Mbps, you have approximately 8,000 kbps of effective video bitrate after accounting for audio (192 kbps), protocol overhead (~5%), and leaving a 10% safety buffer against congestion. This is Twitch's recommended maximum for 1080p60 — meaning a stable 10 Mbps upload is legitimately sufficient for a professional-quality stream.
The Optimal OBS Configuration for 10 Mbps Upload
- Output Resolution: 1920×1080
- Framerate: 60fps (for fast games) or 30fps (for strategy/RPG)
- Encoder: NVENC H.264 New or AMD AMF (hardware encoding)
- Rate Control: CBR (Constant Bit Rate) — more predictable for streaming
- Video Bitrate: 7,500–8,000 kbps
- Audio Bitrate: 192 kbps AAC
- Preset: P4 Quality (NVENC) or Quality (AMF)
- Keyframe Interval: 2 seconds
- Max B-frames: 2 (NVENC) — improves compression by ~15% at same bitrate
Scene Management to Conserve Bandwidth
High-motion, high-detail content (FPS games with busy environments) consumes bitrate aggressively. Static or low-motion content (card games, strategy menus, face cam during chat) uses far less bitrate. At 8,000 kbps, high-motion FPS may show mild artifacts in some scenes; the same bitrate on low-motion RPGs will look exceptional. Choose games that match your bitrate budget for the best viewer experience.
The BRB/Starting Soon Scene Strategy
Create a static "Be Right Back" or "Starting Soon" scene with a non-animated background. During these offline periods, OBS encodes near-zero bitrate, freeing your connection for lag checks, system updates, or game loading. This effectively gives you more peak bandwidth when it matters (gameplay) by reducing consumption during idle periods.
Monitoring Your Stream Quality in Real Time
In OBS, right-click the Stats Dock → View → Stats. Monitor: Dropped frames (must stay at 0%), Output Bitrate (should stay near your target), Encoding Lag (must be 0 ms) and Render Lag (must be 0 ms). If dropped frames appear, reduce bitrate immediately. Run DCSpeedTest from a second device on your network to confirm upload is stable — stream drops often correlate with temporary ISP congestion events.
