How's the physx engine benchmark compare to others?

I want to know the Unity’s Physx engine benchmark compare to other physical engines.
the accuracy-difference btw Real world and etc.
Someone can help? and can someone recommend the simulator for robotics simulation?
plz help. Thanks.

Hello @jjjenny and welcome to the NVIDIA developer forums!

Sadly I don’t know any details about Physx benchmarks, but with respect to robotics simulation I suggest you have a look at NVIDIA Isaac Sim. It is a very extensive robotics toolkit built with Omniverse. Check out the Isaac Sim page for a lot of tutorials and documentation to leverage that tool.

I hope this helps!
