Stuttering Frame Rate When Many People in Scene

Software Unreal Engine
1

Hi everyone!

We’re seeing significant stuttering in the ZED camera feed when there are many people in the scene. We’re using the ZED Plugin for Unreal, latest version v5.2.1.

The stuttering only affects the camera feed. Unreal-rendered elements, such as 3D objects, remain smooth.

Is there anything we can do to reduce this? We’re willing to sacrifice some tracking fidelity, but we’d prefer not to reduce image quality or frame rate.

Thanks for your help!

Hi @emile

Do you have a video showing the problem?
What’s the setup of the host device that you are using with the ZED Plugin for Unreal?

Please also provide details of the configuration that you are using:

  • camera resolution
  • camera frame rate
  • depth mode
  • body tracking mode
  • body tracking configuration

Hi! Thanks for the response.

Sadly, we didn’t get a good video. I should mention that the lighting was a bit bluish, although still reasonably bright.

We’ve tried a couple of machines, ranging from a 3080 Ti with an older Intel processor to a 5090 with the latest R7.

Details:

Camera resolution: 1080p, also tried 720p
Camera frame rate: I don’t think this is set in the Unreal plugin, is it?
Depth mode: Neural
Body tracking mode: Human Body Accurate
Body tracking configuration: See screenshot

Let me know if you need any other details.
