If you see the "Low Performance Warning" as pictured above, don't worry! There any many steps you can take to reduce dropped frames and increase capture performance. Check out the following steps and please see sensor specific recommendations in addition to our general recommendations.
Before following these recommendations, please check our minimum computer specifications to make sure Depthkit can be supported on your system.
Azure Kinect Performance at High Resolutions
If capturing with an Azure Kinect, please reference the hardware we have verified for high resolution capture.
Enable/disable GPU accelerated capture pipeline.
In the Edit menu, go to Preferences to enable/disable GPU hardware acceleration. Your system specifications will determine if the enabling/disabling of the GPU accelerated pipeline is preferred.
Known Issue with AMD Radeon driver 19.30.01.33
If recording 3840x2160 footage with the Azure Kinect on a computer that uses AMD Radeon driver 19.30.01.33, Depthkit may crash if GPU acceleration in enabled in Depthkit preferences. To work around this issue, go into your Depthkit preferences and disable the GPU accelerated video encoder.
Minimize the window size of Depthkit.
Decreasing the size of the application by simply clicking and dragging the corner of the window will reduce dropped frames and increase performance. If using Windows Bootcamp, keep in mind that you may need to set your display scale to 100% in System Settings in addition to resizing your window.
Reduce the resolution of your monitor.
It may increase performance to reduce the resolution of your display. This may be particularly helpful for Nvidia Optimus laptops.
Make sure Depthkit is the active window while recording.
If you hit Record and then click onto another application window, this might drop more frames. For best results, keep Depthkit active as your primary selected window while you are recording.
If recording on an Intel computer, download the Intel Extreme Tuning Utility to update a selection of drivers that may increase performance.
The drivers that will be updated with this utility are below:
- IOCBIOS Device Driver
- Intel® XTU Extension Device
- Intel® XTU Component Device
- ACPI Device Driver
- Watchdog Device Driver
- ICC Proxy Service Version
Ensure that your sensor is receiving adequate power.
- The best way to check this is via the sensor's power indicator LED, located on the back of the device. If the indicator is not a consistent white light, the sensor is not properly powered.
What this means...
Sensor is working properly and powered on
Sensor is powered on, but may not be connected to a USB 3.0 port
Sensor is not receiving adequate power
Amber + flashing white
Sensor is powered on and updating or being reset
- If powering the Azure Kinect with a USB-C to USB-C cable instead of the supplied power adapter, ensure you are using one that can sufficiently power the device.
- Use an active USBactive USB - A cable that buffers the cable signal to provide signal quality. cable
- Avoid USB extenders
- Verify your USB controller is compatible with the Azure Kinect
See details on Sensor Power Recommendations.
Reduce the color resolution.
High color resolutions may contribute to low preformance, especially on less powerful computers. For best performance, set your color resolution to 1080p or lower to see if this will reduce dropped frames.
Performance improvements are currently in development. Until then, please see recommended computers for systems that support high resolution recording.
Ensure that your sensor is securely plugged in and powered on.
If it is a power issue, you may want to try plugging it directly into the power outlet in case an extension cable is causing insufficient power.
Make sure your sensor is connected via a USB-3.1 / USB-C (gen 2) port.
Gen 2 ports have a much higher data transfer rate and will promote a more stable connection and data stream from your depth sensor. If you computer does not have a USB 3.1 (gen 2) port, try a USB to USB-C adapter. Learn more about USB ports and how to find which one you are currently using.
Install the Kinect Configuration Verifer Tool. Plug in the Kinect to your computer and open the Kinect Verifier Tool. Ideally, all sections should be checked green for best performance, with the exception of the USB Controller (you can disregard the yellow warning). If the Verifier indicates a warning, follow the steps below.
You cannot run the Kinect Configuration Verifier while you are running Depthkit, as you will find that the depth/color streams may not show up in Depthkit when both apps are active. With this in mind, once your Kinect performance is confirmed, close the verifier before you open Depthkit.
The Kinect Verifier indicates that my sensor is not connected or there is a warning in the depth/color streams.
Make sure you have your sensor connected to your computer via a USB-3.1 / USB-C (gen 2) port. Gen 2 ports have a much higher data transfer rate and will promote a more stable connection and data stream from your depth sensor. If you computer does not have a USB 3.1 (gen 2) port, try a USB to USB-C adapter.
The Kinect Verifier indicated that my framerate is fluctuating in the Verify Kinect Depth and Color Streams section. Or the sensor seems to be disconnecting repeatedly.
First, update your WDF Kinect Sensor Interface driver. You can find this in the Device Manager, under Kinect sensor devices. In the drop down, right-click on WDF KinectSensor Interface and select update driver.
If that doesn't solve the problem, it may also be due to new Intel CPUs and their power saving features. If that is the case, try to following steps:
- Double click the registry file here that will change these power saving settings.
This registry file will lower your computer battery performance.
- You may also need to disable your USB power saving settings. You can find this going to your Control Panel, select Hardware and Sound and then select Power Options. In this menu, click Change plan settings on your power plan.
- In the next menu, select Change advanced power settings.
- Under USB settings, select USB selective suspend setting and disable.
Reduce the resolution under sensor configuration.
This will reduce the resolution of the color video to improve capture performance.
Make sure you don't have too many applications running in the background. To check this out, open up your Task Manager and click the Performance tab. If your CPU and GPU are over allocated, you may need to quit the other applications to increase Depthkit performance.
You can identify which applications are using up your performance in the Processes tab of the Task Manager. Click on CPU to view the allocation of CPU usage and what programs need to be closed to help performance.
Once the background applications are closed, you will see reduced utilization rates as seen in the example below.
