TLDR: Isaac Sim gets too slow when I run simulation in nav2 tutorial. Are there any ways or tips to increase the FPS of the simulation, could you please introduce them?
Hello.
I am following the Isaac ROS nav2 tutorial (7.2.8. ROS2 Navigation — Omniverse IsaacSim latest documentation). There are no issues with general operations like running Isaac Sim and RViz. However, Isaac Sim, which maintains an average of 30 FPS before running the simulation, drops sharply to 5-6 FPS after running it, making practical use of Isaac Sim difficult.
On the other hand, in an example from the Isaac ROS weekly livestream, which is a bit outdated (https://www.youtube.com/live/x9NPYU7OmBY?si=NavHLoRipeqQR9J0&t=4586), you can see that it maintains an average of 20 FPS. Even that level would not pose a significant problem for usage.
In the video, you can confirm that a TITAN RTX is being used, but I am using an RTX 3080, so despite the absolute performance difference not being significant, why is there such a large FPS difference?
If there are any ways or tips to increase the FPS of the simulation, could you please introduce them?
