NVIDIA PhysX is a proprietary physics engine middleware suite. In simple terms, it allows developers to create games with realistic physics simulations—things like flowing water, exploding debris, cloth movement, and particle effects. While modern games utilize physics engines built into engines like Unreal Engine 5 or Unity, many older titles relied heavily on this standalone middleware.
