Quick answer: A VPS can improve your Twitch streams by: 1) Acting as a relay server for reliability, 2) Running cloud OBS to offload encoding, 3) Adding professional features like backup streaming, 4) Enabling multistreaming to Kick/YouTube. Most streamers benefit from a €10-20/month VPS for significant quality improvements.
Why Use a VPS for Twitch Streaming?
Common Problems VPS Solves
| Problem | How VPS Helps | |---------|---------------| | CPU maxed while gaming | VPS does the encoding | | Dropped frames from unstable internet | VPS buffers and retransmits | | Want to multistream | VPS pushes to multiple platforms | | OBS crashes mid-stream | VPS provides backup | | Need 24/7 reruns | VPS runs without your PC |
Who Benefits Most
- Gamers with older CPUs: Offload x264 encoding
- Streamers on unstable connections: VPS smooths interruptions
- Multi-platform streamers: One upload, many destinations
- Professional streamers: Redundancy and features
Method 1: Relay Server (Most Popular)
Use VPS as an intermediary between your OBS and Twitch.

- Multistream: Push to Kick/YouTube from same stream
- Buffering: VPS handles brief upload drops
- Recording: Save archive on VPS
VPS Requirements
| Stream Quality | CPU | RAM | Bandwidth | Price | |----------------|-----|-----|-----------|-------| | 1080p30 | 2 cores | 2GB | 5TB | €5-10 | | 1080p60 | 2 cores | 2GB | 10TB | €10-15 | | + Transcoding | 4 cores | 4GB | 10TB | €15-25 |
Setup Guide
Step 1: Install NGINX-RTMP
sudo apt update
sudo apt install nginx libnginx-mod-rtmp -y
Step 2: Configure NGINX
sudo nano /etc/nginx/nginx.conf
Add at the bottom (outside http block):
rtmp {
server {
listen 1935;
chunk_size 4096;
buflen 2s;
application live {
live on;
record off;
# Only allow your IP
allow publish YOUR_HOME_IP;
deny publish all;
# Push to Twitch
push rtmp://live.twitch.tv/app/YOUR_TWITCH_STREAM_KEY;
}
}
}
Step 3: Restart NGINX
sudo nginx -t
sudo systemctl restart nginx
Step 4: Configure OBS
Settings → Stream:
- Service: Custom
- Server:
rtmp://YOUR_VPS_IP/live - Stream Key:
mystream(or anything)
Now your stream goes to VPS, which forwards to Twitch.
Method 2: Cloud Encoding (Offload CPU)
Run OBS on the VPS and send your gameplay to it.
How It Works
Your PC (Game + NDI/RTMP output)
│
│ Video capture (high quality)
▼
VPS (OBS running in cloud)
│
│ Encodes + streams
▼
Twitch
Benefits
- Zero local encoding: All CPU goes to gaming
- Better quality: Can use slow x264 preset
- Add overlays remotely: Access OBS from anywhere
- 24/7 capability: Cloud OBS runs forever
VPS Requirements
| Quality | CPU | RAM | GPU | Price | |---------|-----|-----|-----|-------| | 720p60 | 4 cores | 4GB | None | €15-20 | | 1080p30 | 4 cores | 4GB | None | €15-20 | | 1080p60 | 4-6 cores | 8GB | None/GPU | €25-50 |
Setup Guide
See our Cloud OBS VPS Setup Guide for full instructions.
Quick overview:
- Install desktop environment (XFCE)
- Install VNC server
- Install OBS Studio
- Send local video via NDI or RTMP
- OBS on VPS adds overlays and streams
Method 3: Backup/Failover Streaming
Never lose a stream due to crashes or disconnects.
How It Works
Primary: Your PC → OBS → Twitch
Backup: VPS runs fallback content
If primary fails → VPS automatically takes over
Setup with FFmpeg Failover
On VPS, create failover script:
nano /home/user/failover.sh
#!/bin/bash
PRIMARY="rtmp://localhost/live/mystream"
BACKUP_VIDEO="/home/user/brb-loop.mp4"
TWITCH_KEY="YOUR_TWITCH_KEY"
while true; do
# Try to relay primary stream
timeout 10 ffprobe -v quiet "$PRIMARY"
if [ $? -eq 0 ]; then
# Primary is live, relay it
ffmpeg -i "$PRIMARY" -c copy -f flv "rtmp://live.twitch.tv/app/$TWITCH_KEY"
else
# Primary is down, play backup
echo "Primary down, playing backup..."
ffmpeg -re -stream_loop -1 -i "$BACKUP_VIDEO" \
-c:v libx264 -preset veryfast -b:v 4000k \
-c:a aac -b:a 160k \
-f flv "rtmp://live.twitch.tv/app/$TWITCH_KEY"
fi
sleep 5
done
Modify NGINX to receive primary:
application live {
live on;
record off;
}
Your OBS streams to VPS. If it stops, VPS plays your "Be Right Back" video.
Method 4: Dual-Stream Redundancy
Stream from two locations simultaneously for maximum reliability.
Setup
Location 1 (Your PC):
- OBS → VPS → Twitch
Location 2 (VPS):
- Receives your stream
- Has fallback content
NGINX config for dual-input:
application live {
live on;
# Record to disk
record all;
record_path /var/recordings;
record_suffix _%Y-%m-%d.flv;
# Push to Twitch
push rtmp://live.twitch.tv/app/TWITCH_KEY;
}
If your main stream dies, VPS has recording to reference or loop.
Adding Professional Features
1. Stream Recording
Record every stream on VPS:
application live {
live on;
record all;
record_path /var/recordings;
record_suffix _%Y-%m-%d_%H-%M.flv;
record_unique on;
# Convert to MP4 when done
exec_record_done ffmpeg -i $path -c copy $dirname/$basename.mp4;
push rtmp://live.twitch.tv/app/KEY;
}
Benefits:
- Backup of all content
- Source for YouTube highlights
- Higher quality than Twitch VOD
2. Multi-Bitrate Transcoding
Send one stream, output multiple qualities:
application live {
live on;
# Transcode to 720p
exec_push ffmpeg -i rtmp://localhost/live/$name
-c:v libx264 -preset fast -b:v 3000k -s 1280x720
-c:a aac -b:a 128k
-f flv rtmp://localhost/720p/$name;
# Transcode to 480p
exec_push ffmpeg -i rtmp://localhost/live/$name
-c:v libx264 -preset fast -b:v 1500k -s 854x480
-c:a aac -b:a 96k
-f flv rtmp://localhost/480p/$name;
}
Useful for custom players or serving mobile viewers.
3. Stream Delay
Add delay for esports/competitive to prevent stream sniping:
application live {
live on;
# 30-second delay buffer
exec_push ffmpeg -i rtmp://localhost/live/$name
-c copy
-f fifo -fifo_format flv
-attempt_recovery 1
-recovery_wait_time 1
-map 0
"rtmp://localhost/delayed/$name";
}
application delayed {
live on;
push rtmp://live.twitch.tv/app/KEY;
}
4. Overlay Injection
Add overlays server-side:
ffmpeg -i rtmp://localhost/live/stream \
-i /path/to/overlay.png \
-filter_complex "overlay=W-w-10:10" \
-c:v libx264 -preset veryfast \
-c:a copy \
-f flv rtmp://live.twitch.tv/app/KEY
Useful for adding sponsor logos or alerts without touching local OBS.
Optimizing for Twitch
Twitch Stream Requirements
| Quality | Resolution | FPS | Bitrate | |---------|------------|-----|---------| | Affiliate | 1080p max | 60 | 6000 kbps | | Partner | 1080p60 | 60 | 8000 kbps | | Recommended | 720p60 or 1080p30 | 60/30 | 4500-6000 kbps |
Twitch Ingest Servers
Use closest server for lowest latency:
| Region | Server | |--------|--------| | Auto | rtmp://live.twitch.tv/app | | Amsterdam | rtmp://live-ams.twitch.tv/app | | Frankfurt | rtmp://live-fra.twitch.tv/app | | London | rtmp://live-lhr.twitch.tv/app | | US East | rtmp://live-iad.twitch.tv/app | | US West | rtmp://live-sjc.twitch.tv/app |
For VPS in Netherlands, use Amsterdam ingest:
push rtmp://live-ams.twitch.tv/app/YOUR_KEY;
Optimal NGINX Buffer Settings
rtmp {
server {
listen 1935;
chunk_size 4096;
# Smooth variable upload speeds
buflen 2s;
# Increase if network is unstable
# buflen 5s;
application live {
live on;
# Prevent timeout on slow connections
wait_video on;
wait_key on;
push rtmp://live-ams.twitch.tv/app/KEY;
}
}
}
Troubleshooting
Stream Dropping Frequently
# Check VPS → Twitch connection
curl -I rtmp://live.twitch.tv
# Check NGINX error log
tail -f /var/log/nginx/error.log
# Check VPS bandwidth
iftop
Common causes:
- VPS bandwidth insufficient (upgrade plan)
- Twitch ingest overloaded (try different server)
- RTMP timeout (increase buflen)
High Latency
If stream delay is too high:
# Reduce buffer
buflen 1s;
# Or use low-latency mode in Twitch dashboard
Also enable Low Latency in Twitch Dashboard → Settings → Stream.
Frame Drops on Upload
# Check your upload speed
speedtest-cli
# You need 1.5x your bitrate (9+ Mbps for 6000 kbps stream)
If upload is borderline:
- Lower bitrate to 4500 kbps
- Or use SRT instead of RTMP (handles packet loss better)
VPS Overloaded
# Check CPU usage
htop
# If CPU is maxed, you're transcoding too much
# Solutions:
# - Don't transcode (passthrough only)
# - Upgrade VPS
# - Use faster preset
SRT Instead of RTMP
SRT (Secure Reliable Transport) handles unstable connections better.
VPS SRT Relay Setup
# Install SRT tools
sudo apt install srt-tools -y
Create SRT to RTMP relay:
nano /home/user/srt-relay.sh
#!/bin/bash
srt-live-transmit \
"srt://:9999?mode=listener&latency=1000" \
file://con | \
ffmpeg -i - -c copy -f flv rtmp://live.twitch.tv/app/YOUR_KEY
OBS Settings:
- Service: Custom
- Server:
srt://YOUR_VPS_IP:9999 - Stream Key: (leave empty)
SRT recovers from 5-10% packet loss gracefully.

When VPS Doesn't Help
GPU Encoding (NVENC)
If you have RTX GPU, NVENC encoding has near-zero CPU impact. VPS won't improve performance.
When NVENC is enough:
- RTX 2060 or better
- Single-platform streaming
- Stable home internet
When VPS still helps with NVENC:
- Multistreaming
- 24/7 reruns
- Backup/failover
- Recording remotely
Excellent Home Internet
If you have fiber with 99.9% uptime, relay benefits are minimal. VPS helps more for:
- DSL/cable with variable speeds
- Shared household bandwidth
- Mobile/cellular connections
Real-World Examples
Example 1: Gaming Streamer
Problem: CPU at 100% while gaming, stream stutters
Solution: VPS relay with slight buffer
Config:
application live {
live on;
buflen 2s;
push rtmp://live.twitch.tv/app/KEY;
}
Result: Local OBS uses "faster" preset, VPS handles buffering. Smooth gameplay and stream.
Example 2: IRL Streamer
Problem: Drops during mobile streams
Solution: SRT relay through VPS
Config: SRT listener → FFmpeg → Twitch RTMP
Result: Stream survives 10% packet loss without visible issues.
Example 3: Multi-Platform Creator
Problem: Wants to stream to Twitch + Kick + YouTube
Solution: VPS multistream relay
Config:
application live {
live on;
push rtmp://live.twitch.tv/app/TWITCH_KEY;
push rtmp://ingest.kick.com/live/KICK_KEY;
push rtmp://a.rtmp.youtube.com/live2/YT_KEY;
}
Result: One upload, three platforms.
Frequently Asked Questions
Will this improve my stream quality?
