Optimize Blue Iris for lower CPU usage with expert tips! Learn to enable hardware acceleration, adjust settings, and improve performance for a smoother experience.
In this article, we explore the best ways to reduce CPU usage in Blue Iris for a faster, more efficient surveillance system. You’ll learn how to enable hardware acceleration, optimize camera settings, and use direct-to-disk recording to improve performance. Follow these expert tips to keep your system running smoothly while managing multiple camera feeds.
Why Does Blue Iris Use So Much CPU?
Before we dive into optimizations, let’s first understand why Blue Iris can consume a high percentage of your CPU resources:
- Multiple High-Resolution Cameras – Running several 1080p or 4K cameras at high frame rates (30+ FPS) puts a heavy load on your processor.
- Continuous Recording – If your system is set to record 24/7 instead of motion detection-based recording, the CPU load increases significantly.
- Motion Detection Processing – Built-in motion detection is CPU-intensive, especially when running on multiple cameras simultaneously.
- Software Decoding – If hardware acceleration isn’t enabled, the CPU has to process all video feeds instead of offloading work to the GPU.
- Improper Settings – Default Blue Iris settings may not be optimized for your hardware, leading to unnecessary CPU strain.
Understanding these factors is the first step toward reducing CPU usage in Blue Iris. Now, let’s move on to effective solutions.
Best Ways to Reduce CPU Usage in Blue Iris:
1. Enable Hardware Acceleration:
One of the most effective ways to lower CPU usage in Blue Iris is by enabling hardware acceleration. This allows the software to offload video decoding from the CPU to the GPU, significantly reducing processor load.
How to Enable Hardware Acceleration in Blue Iris:
- Open Blue Iris and go to Settings (gear icon).
- Navigate to Camera settings > Video tab.
- Find the Hardware Accelerated Decode option.
- Select Intel+VPP, Intel, or NVIDIA (depending on your hardware).
- Click Apply and restart Blue Iris.
🔹 Tip: If you’re using an Intel CPU with Quick Sync Video (QSV), enabling hardware acceleration can reduce CPU usage by 50% or more!
2. Adjust Frame Rates & Resolutions:
Running cameras at high resolutions (4K) and frame rates (30-60 FPS) can overload your CPU. Instead, consider lowering these settings:
- Reduce frame rates to 10-15 FPS (still sufficient for security footage).
- Lower the resolution (e.g., from 4K to 1080p) for non-critical cameras.
- Enable variable bitrate (VBR) instead of constant bitrate (CBR) to reduce CPU strain.
🔹 Tip: Most security scenarios don’t require ultra-high frame rates. A lower frame rate significantly reduces CPU load while still providing clear footage.

3. Use Direct-to-Disk Recording:
By default, Blue Iris processes video before saving it, which increases CPU usage. To minimize this, enable Direct-to-Disk recording so that video streams are saved without unnecessary processing.
Steps to Enable Direct-to-Disk Recording:
- Open Blue Iris and go to Camera settings.
- Click the Record tab.
- Check the box for Direct-to-disk recording.
- Click Apply.
🔹 Note: If you enable Direct-to-Disk, overlays such as timestamps must be embedded by the camera instead of Blue Iris.
4. Optimize Motion Detection Settings:
Blue Iris’s motion detection algorithm can be CPU-intensive, especially if it’s running on multiple cameras. To optimize:
- Use zones and regions to limit motion detection to specific areas.
- Increase the minimum object size to avoid processing small, irrelevant movements.
- Reduce the frame analysis rate (e.g., from 100% to 50%).
🔹 Tip: Switching to AI-based motion detection (using DeepStack or CodeProject AI) can help reduce false alerts while optimizing CPU performance.
5. Limit Camera Streams:
If you’re running multiple cameras, consider reducing the number of active streams:
- Use sub-streams for live viewing while keeping high-resolution streams only for recording.
- Disable cameras that aren’t needed in real-time monitoring.
- Turn off audio recording if unnecessary.
🔹 Tip: Some IP cameras support dual-streaming, where a lower-resolution sub-stream is used for live viewing, saving CPU power.
6. Adjust Blue Iris Priority & Background Processes:
Windows background tasks and high-priority settings can impact CPU performance. To optimize:
- Set Blue Iris’s process priority to Below Normal in Task Manager (Right-click on BlueIris.exe > Set Priority).
- Disable unnecessary background applications while Blue Iris is running.
- Ensure Blue Iris is excluded from Windows Defender real-time scanning.
🔹 Tip: Running Blue Iris on a dedicated machine with minimal background applications improves performance.
7. Optimize Storage Settings:
Inefficient storage configurations can cause high CPU usage. To improve performance:
- Use a separate drive (preferably an SSD) for Blue Iris recordings.
- Enable pre-allocated disk space to reduce write overhead.
- Use the Recycle feature in Blue Iris to manage old recordings efficiently.
🔹 Tip: Avoid using external USB drives for continuous recording, as they can bottleneck performance.
8. Keep Blue Iris Updated:
Software updates often include bug fixes and performance improvements. Make sure you’re running the latest version of Blue Iris:
- Open Blue Iris and go to Help > About.
- Click Check for updates and install if available.
🔹 Tip: Blue Iris updates sometimes introduce new optimizations for CPU usage—always keep it up to date!
FAQ’s: Blueiris Using Cpu!
1. How much CPU should Blue Iris use?
Ideally, CPU usage should remain under 30-50% under normal conditions. If it’s consistently above 80-90%, optimization is needed.

Blue Iris benefits from Intel CPUs with Quick Sync Video (QSV) for hardware acceleration. However, AMD CPUs with a dedicated GPU (NVIDIA/AMD) also perform well.
4. Can I use an external GPU for Blue Iris?
Yes! Using an NVIDIA GPU (like GTX 1650 or better) with NVENC support can offload video processing from the CPU, reducing usage.
5. What is the best PC setup for Blue Iris?
A dedicated PC with an Intel i7/i9, Quick Sync support, 16GB RAM, SSD storage, and a dedicated GPU is recommended for handling multiple high-resolution cameras.
