Hello, I have been using Astro for RTAB-Map on a Jetson AGX Orin with Ubuntu 20.04 and an Astro Pro camera. For some reason, when launching examples, my image updates are very slow, and real-time synchronization is not possible. The maintainer of RTAB-Map suggested I check the Hz (frequency), and I found that my Hz is even lower than 4. Can you please tell me why this is happening? Is it a driver issue or an issue with the camera itself?
