Each stroke course is 1000s of photos. You want them to spend the money shooting them over instead of shooting new courses? Further, animating the water consumes cpu cycles and is a very bad idea for those people who are already enduring meter stutter.
Frankly, if you find the graphics too pixelated you have extra superior vision or you are playing on your 54" TV screen, or similar.
Strictly my personal opinion. You are entitled to your own, even if it's wrong.
