Folks, A GPU solution is great for the rendering, but it doesn't support all the other things on the cpu side that need to know about the ocean. Wakes, bow waves, floating objects, things falling into the water generating splashes, interaction with land ... all these things need to query the ocean surface for height/geometry info.

I have used it with, I think it was 512x521, images with 60 FPS. So for your case it should be enough. If CUDA doesn't fit well your needs, then you can take a look into just GPGPU FFT algorithms. I have seen on the nVidia's webpage an OpenGL shader based application which can do compute FFT on the GPU. Even more I could try to manage to create something for osgPPU, then you could use from there, if you like.
