Changing Physx config improve FPS and solve the TLAS warning but I do not understand what am I doing.

So using there config increase the FPS in both training and playing, but non of the parameters shown here has TLAS in their name.

        physx=PhysxCfg(
            bounce_threshold_velocity=0.2,
            gpu_found_lost_aggregate_pairs_capacity = 1024 * 1024 * 4,
            gpu_total_aggregate_pairs_capacity = 16 * 1024,
            friction_correlation_distance = 0.00625,
        )

Also, before applying these changes, in nvidia-smi, the Volatile GPU utilization is 100%.
So, how can I figure out the set of parameters that help me fully utilize my GPU?

Thanks for posting this. Could you share the warning you are getting, and which versions of Isaac Lab and Isaac Sim are you using?
