Isaac Sim: slow launch time

Hi,

At first, when I only installed Isaac Sim 4.2.0, the launch time was under 10 seconds. Now it takes about 16 seconds. I was just wondering what could be the reason for such an increase. I am always comparing the performance by opening the empty scene through the Omniverse Launcher.

Additional Information

What I’ve Tried

I tried to even reinstall Ubuntu, but the result is same here. I changed several times CUDA version and Drivers.

Additional Context

Should I change the driver or the CUDA version. Why does it say “CUDA Toolkit 11.8” even if I built the CUDA 12.6 for 550 driver.

Could you elaborate on what changes caused the increase in launch time from 10 seconds to 16 seconds? Were any additional extensions enabled?

The only extension used is ROS2 bridge. I dont think I enabled anything else.

Could you provide the detailed steps that occurred between seeing the 10-second and 16-second launch times?

No additional steps happening except the terminal output I provided above. It is during the Isaac Sim launch.
