Any Guidance for More Realistic Isaac Simulation? (PhysX Settings)

Hi everyone,

I’ve found that adjusting the ‘Time steps per second’ significantly affects not only the substep dt but also the physical behavior of the simulation. I am interested in achieving a more realistic Isaac simulation but lack knowledge about how to fine-tune specific settings in the ‘Advanced’ section.

I understand that achieving realistic tuning is challenging, but I am looking for guidance on how to adjust these settings to improve simulation accuracy. Currently, I am making adjustments based on visual observation and heuristic methods, but I believe a more systematic, engineering-based approach would be more effective.

In our team, we currently set the ‘Time steps per second’ to 60-120 for task-level operations, but we hope to configure it to 1000-4000 or even higher for control-level operations. Are there any guidelines or resources that could help me better understand and configure these settings?

Thank you!
