Water Medium or High? Any difference in FPS?

Im tempted to leave it on High, because it simply looks so gorgeous. It also looks pretty good on Medium. Anyways, I don't think it makes much a FPS hit if any at all. Anyone notice?

For reason I can't produce whitecaps, even with a 50 knot wind. Whats the secret?
