Any sort of cool real time interactive physics would be better than how raytracing is used right now.

If you're mimicking a wave effect like in the OP, Sea of Thieves, Batman Arkham Knight, you're more than likely using a shader effect on the GPU to simulate and displace the vertices on the mesh. And if you're straight up simulating an actual fluid, I think it's still preferred to use GPUs like this guy. https://youtu.be/_8Ed8ET9gBU
