Correspondingly, what does PhysX mean?

PhysX is an Nvidia-based API designed to provide a standard, GPU accelerated way of modelling realistic object dynamics in 3D environments. Mirror's Edge was one of the first showpiece games for PhysX cloth physics.

Furthermore, do games still use PhysX? PhysX is very much alive and currently the most popular physics middleware alongside Havok. It's baked into Unity and Unreal Engine 4 and a great number of other games also use it. GPU accelerated PhysX on the other hand doesn't really have many games using it.

Secondly, is PhysX needed?

PhysX only works with nvidia cards, but it isn't necessary at all. In fact, only a few games use PhysX.

Is PhysX GPU or CPU better?

Intel and AMD say it's better to run physics on the CPU. What is NVIDIA's position? PhysX runs faster and will deliver more realism by running on the GPU. Running PhysX on a mid-to-high-end GeForce GPU will enable 10-20 times more effects and visual fidelity than physics running on a high-end CPU.
