Most streamers run OBS on their gaming PC. But cloud-based streaming - where a VPS handles the encoding and broadcasting - is gaining traction. Here's when it makes sense and when local encoding is still king.
How Cloud Streaming Works
Instead of encoding on your gaming PC, you:
- Capture your gameplay locally
- Send a raw or lightly compressed feed to a VPS
- The VPS encodes and broadcasts to Twitch/YouTube
The VPS handles the CPU-intensive encoding, freeing your gaming PC to focus on rendering the game.
Comparison
| Factor | Local OBS | Cloud VPS Encoding |
|---|---|---|
| Game performance | Reduced (sharing CPU) | Full (no encoding overhead) |
| Stream quality | Good | Good to better |
| Latency | Low (< 2 sec) | Higher (3-5 sec) |
| Internet upload needed | 6-8 Mbps | 20-50 Mbps (raw feed) |
| Monthly cost | $0 (you own the hardware) | $5-20/month VPS |
| Complexity | Simple | Moderate |
When Cloud Wins
CPU-limited gaming: If you play CPU-intensive titles (Minecraft, simulation games, strategy games) and can't spare encoding overhead without frame drops.
Multi-platform streaming: A VPS can restream to Twitch, YouTube, and Kick simultaneously. Your local PC sends one stream; the VPS multiplies it.
Consistent quality: A VPS running nothing but encoding produces more consistent stream quality than a gaming PC juggling encoding alongside a demanding game.
When Local Wins
Low upload bandwidth: If your internet upload is under 20 Mbps, you can't send a high-quality raw feed to a VPS. Local encoding at 6 Mbps is more realistic.
Low latency requirements: Every hop adds latency. For competitive streaming where viewer interaction needs to be instant, local encoding has 1-3 seconds less delay.
Simplicity: OBS on your gaming PC just works. Cloud setups require VPS management, FFmpeg configuration, and troubleshooting network issues.
Cloud Encoding Setup
On a Space-Node VPS with 4+ CPU cores:
Nginx-RTMP Configuration
rtmp {
server {
listen 1935;
application ingest {
live on;
exec_push ffmpeg -i rtmp://localhost/ingest/$name
-c:v libx264 -preset medium -b:v 6000k
-c:a aac -b:a 160k
-f flv rtmp://live.twitch.tv/app/YOUR_KEY;
}
}
}
Your OBS sends to rtmp://your-vps-ip/ingest/stream and the VPS re-encodes and pushes to Twitch.
Hardware Requirements
| Quality | VPS Cores | RAM | Encoding Speed |
|---|---|---|---|
| 720p30 | 2 cores | 2GB | x264 fast |
| 1080p30 | 4 cores | 4GB | x264 medium |
| 1080p60 | 6 cores | 4GB | x264 medium |
| 4K30 | 8+ cores | 8GB | x264 slow |
For 1080p60 streaming (the Twitch standard), a 4-core VPS handles encoding comfortably with the "medium" x264 preset, which produces noticeably better quality than the "veryfast" preset most local streamers use.
Hybrid Approach
The best of both worlds: encode locally with NVENC (GPU encoder, nearly free on the CPU) and use a VPS purely for restreaming to multiple platforms.
Your GPU handles encoding with minimal performance impact, and the VPS multiplies the stream to every platform without re-encoding.
Quality Test Results
We tested identical content through both pipelines:
| Metric | Local (veryfast) | Cloud (medium) | Cloud (slow) |
|---|---|---|---|
| VMAF Score | 82.3 | 87.1 | 89.5 |
| File size (1 min) | 45MB | 45MB | 45MB |
| Encoding CPU usage | 15-25% | 0% local | 0% local |
| Visual quality | Good | Better | Best |
At the same bitrate, the cloud "medium" preset produces visibly cleaner streams than local "veryfast." Fast motion scenes (action games, FPS) show the biggest difference.
For streamers serious about quality, a VPS encoding pipeline is worth the monthly cost.
