RT-DETR + ZED on Jetson AGX Orin: can it run at 30/60 FPS?

Hi everyone,

I’m running RT-DETR with a ZED camera on Jetson AGX Orin using the default Isaac ROS weights/config.

The ZED is set to 30 FPS, but when I run the detection pipeline, the image stream drops to around 11–14 FPS.

Is this expected for RT-DETR on AGX Orin?
Is the bottleneck likely the model inference, ZED pipeline, ROS queues/backpressure, image conversion, or GPU/CPU memory bandwidth?

What confuses me is: if inference is slow, why does the ZED camera stream FPS also drop? Does this mean the whole ROS pipeline is being bottlenecked?

Any profiling tips would be appreciated — TensorRT inference time, ZED node FPS, CPU/GPU usage, etc.

Welcome to the StereoLabs community.

I recommend you place questions concerning Isaac ROS performance in the NVIDIA Developer Forum to get in touch with an NVIDIA engineer who can provide you with updated details.
