Upgrading SDK from 4.2.3 to 4.2.5 leads to significant perf drop

[dh662]

Hi,

Setup:

• ZED X camera on Jetson
• Jetpack 6.0 / Tegra 36.3.0
• CUDA 12.2
• Quad link drivers 1.2.1

Running ZED_Explorer on identical setup, clean L4T 36.3.0 container with:

A) SDK 4.2.3 → runs 1200 at 60Hz with 0 frame drops

B) SDK 4.2.5 → running 1080p at 30Hz only runs at 15Hz leading to significant frame drop

Similarly, when running with ROS2

ros2 launch zed_wrapper zed_camera.launch.py camera_model:=zed and running ros2 topic echo /diagnostics in another terminal session, the processing time doubles for 4.2.5

Please upgrade the ZED ROS2 Wrapper to the latest version in the master branch and upgrade the ZED X Driver to v1.2.2

Extra note:

Also when I arrange the internal grab rate to 15 and publishing to 15, it drops to 7.5 fps. As there is a hidden " /2 " division somewehere
