Detailed Verification of Physical Calculations During Simulation

How to time codes, frames, and physics steps per second relate to each other?

The simulation stepping (“Time steps per second”) should be independent here, thats strictly defining the substepping for physics simulation. However to be confused even more there is a fifth parameter that you are missing. There is also Min Simulation Frame Rate (should be in physics settings window). Now this defines the lower bound how much physics should substep, otherwise the simulation would continuously slow down the whole application if the general frame rate is not high enough. The de…

How can I raise the frame rate of physics simulations?

Hi, yes its possible to set the simulation frame rate, on the PhysicsScene you can set the Time Steps Per Second, this defines the fixed timestep for physics simulation. The simulation will to substepping with the given timestep on the Physics Scene: [image] To speedup the rigid body simulation, most of the time is usually spend in updating back the USD, you can enable omni.physx.flatcache extension to skip USD writes and write to Fabric, that will avoid the heavy writes.
