Improving Performance of D400e Cameras on Windows#

If you’re testing or developing with FRAMOS D400e cameras on a Windows machine, you may experience performance issues such as dropped frames or unstable streaming. Although the best performance is typically achieved on a clean Linux setup, you can still improve performance on Windows using the following recommendations.

Note

Ensure that you are using the latest version of the RealSense SDK and firmware. Visit the official download page here: Intel® RealSense™ SDK Downloads

Steps to Improve Performance#

1. Close background applications#

Applications like Microsoft Teams, Outlook, and other CPU/network-heavy software can interfere with real-time streaming.

  • Open Task Manager

  • Go to the Processes tab

  • Right-click and End Task for unnecessary apps

2. Optimize network adapter settings#

  • Open Control Panel → Network and Sharing Center

  • Click on your Ethernet connection → Properties

  • Click Configure under your network adapter

  • Navigate to the Advanced tab

  • Set the following properties to their maximum values:

    • Receive Buffers

    • Jumbo Packets

3. Set CPU affinity for RealSense Viewer#

Limiting the viewer to specific CPU cores can improve stability and reduce context switching.

  • Launch RealSense Viewer

  • Open Task Manager

  • Go to the Details tab

  • Right-click on realsense-viewer.exe → Set affinity

  • Deselect the first two cores and select only CPU 2 and CPU 3

Tip

For production-grade performance, it is recommended to use a clean Ubuntu or Debian-based Linux environment with real-time kernel support and tuned network settings.
