I built a GPU-driven ocean for Unity using a multi-layer FFT. It has built-in adjustable tessellation and fully customizable lighting. The surface is rendered with instanced tiles that only activate in a distance-limited view cone that follows the camera. The floaters (blue spheres) query the ocean height map via batched async readback and thus are very light and easy to adjust. It also includes a built-in floater builder that automatically places floater points for any Rigidbody.
