tcmae: can they make the water move, in other words, can you see the waves splashing while your playing the game?
Not unless they modify/expand the present technology that they use to create courses. The water at Bethpage, Kiawah, etc., is perfectly lifeless. While that's pretty strange, you can kind of get used to it, because those are primarily still water surfaces by nature anyway.
But a hole like hole 7 at Pebble Beach, without the splashing waves and breaking surf... it probably wouldn't seem right to see a photograph of "frozen" waves instead. I've noticed that in the Wolf Creek CTTH on this site, the graphic artists have at least incorporated some kind of movement in the photographed water surfaces in order to create a "shimmering" effect, but that's still a long way from resembling realistic flow of water. The lack of sound effects, too, would be highly noticeable at a course like Pebble Beach.
