Can I have two separated scenes?

We are investigating if we can use PhysX for our project. We need to do simulations in two completely separated worlds (scenes). Each will have its own acotors and its own simulation tick rate. So can we do that using PhysX?
And if so, will it be possible to use the GPU acceleration for only one of them?

Hope someone can answer these questions. Thx.

you can by using PxPhysics::createScene multiple times. It takes a scene descriptor object, that determines if you want to use CPU or GPU and other solver.
