12:48:32 [simulation_context.py] WARNING: The enable_external_forces_every_iteration parameter in the PhysxCfg is set to False. If you are experiencing noisy velocities, consider enabling this flag. You may need to slightly increase the number of velocity iterations (setting it to 1 or 2 rather than 0), together with this flag, to improve the accuracy of velocity updates.
