Question 1

How to enable GPU acceleration in PhysX 3.4?

Accepted Answer

GPU acceleration is supported through the deprecated APEX SDK, but for core PhysX, it's limited. For GPU-based simulations, you might need to use external replacements like FleX or configure build settings carefully, as noted in the README.

Question 2

PhysX vs Bullet Physics: which is better for indie games?

Accepted Answer

PhysX is industry-focused with multi-platform and GPU support, but has a steeper learning curve and complex setup. Bullet is open-source with a more accessible community, often preferred for indie projects due to easier integration and flexibility.

Question 3

Can PhysX be used with Unity or Unreal Engine?

Accepted Answer

Unreal Engine has built-in PhysX integration. For Unity, you typically need third-party wrappers or plugins, as Unity uses its own physics system or Nvidia-provided tools for specific features, adding integration overhead.

Question 4

What are the system requirements for running PhysX simulations?

Accepted Answer

PhysX is designed to scale from mobile devices to high-end PCs, with performance depending on scene complexity. It requires multi-core CPUs for optimal performance, and GPU acceleration can enhance simulations but may need additional setup.

Question 5

How to simulate realistic vehicle physics in PhysX?

Accepted Answer

Use the specialized vehicle components included in the SDK, such as suspension, tires, and drivetrain models. Configure parameters like mass, friction coefficients, and suspension stiffness through the provided APIs for desired behavior.

Question 6

Is PhysX 3.4 still supported by NVIDIA?

Accepted Answer

As an open-source release from 2018, it's available for use, but for the latest features and official support, check newer versions or NVIDIA's GameWorks documentation, as active development may have shifted to updated branches.
