GPU not working when add ROS_DOMAIN_ID to terminal

[m15056757832]

When I run the isaacsim4.2 program in python and publish the data through ros2, when I configure ROS_DOMAIN_ID in the terminal and run the isaacsim program again, the GPU utilization is almost 0 and the rendering speed in the simulator becomes much slower.

Before

After ‘export ROS_DOMAIN_ID=10’ in terminal

Hi @m15056757832 welcome to the community! Do you observe the same issue in Isaac Sim 4.5, which is our latest version?
