In this guide, I'll show you exactly how to set up OBS display capture for CS:GO stretched resolution without any quality loss or black bars.

First, let's ensure your CS:GO is properly set up for stretched resolution:

1. Right-click CS:GO in Steam
2. Select Properties
3. Add "-full -w 1920 -h 1080" to Launch Options (adjust numbers to your resolution)
4. Set Aspect Ratio to 4:3 and Scaling Mode to Stretched in your GPU settings

Now for the OBS setup:

1. Open OBS Studio
2. Click the + icon under Sources
3. Select "Display Capture"
4. Name your source (e.g., "CS:GO Capture")
5. Choose your main monitor
6. Check "Transform" in source properties

Important settings to adjust in OBS:

1. Right-click your Display Capture source
2. Select Transform → Edit Transform
3. Set Stretch to Screen: Yes
4. Apply and close

For optimal performance, configure these additional OBS settings:

1. Go to Settings → Video
2. Set Base Resolution to match your monitor
3. Set Output Resolution to your streaming/recording preference
4. Keep FPS at 60 (or higher if your setup can handle it)

Quick troubleshooting tips:

If you see black bars:

• Double-check your GPU settings are set to "Full-screen" or "Stretched"
• Verify OBS Transform settings are correct
• Ensure CS:GO is running in true fullscreen mode

If you experience performance issues:

• Use Game Capture instead of Display Capture if possible
• Lower your recording quality settings
• Enable NVENC (if using NVIDIA) or AMF (if using AMD)

These settings should give you perfect CS:GO stretched capture in OBS. Remember to test your setup before starting any serious recording or streaming session.

For optimal streaming quality, I recommend using these final settings:

• Encoder: NVENC (New) if available
• Rate Control: CBR
• Bitrate: 6000 for streaming (adjust based on your internet)
• Keyframe Interval: 2
• Preset: Quality
• Profile: high
• Look-ahead: Disabled
• Psycho Visual Tuning: Enabled

That's all you need to capture CS:GO stretched perfectly in OBS. Test your setup with a quick recording to ensure everything looks correct before going live.
