Low FPS in Isaac Sim when increasing PhysicsScene Time Steps Per Second

Omniverse Isaac Sim

Isaac Sim Version

[V] 4.5.0

Operating System

[V] Windows 10

GPU Information

  • Model: RTX A4000
  • Driver Version: 566.03

I’m experiencing a significant drop in FPS when increasing the Time Steps Per Second in the PhysicsScene of Isaac Sim. Specifically:

  • When I set Time Steps Per Second to 200, the FPS drops to 10.
  • During simulation, my GPU, Process Memory shows 10GB of available memory.

I’m looking for ways to improve the FPS while maintaining a higher Time Steps Per Second.
Please let me know. Thank you

Please check the memory usage and the GPU utilization using nvidia-smi to see if it’s hitting any limits.
