I cant see the waterfall animation, it just looks like vertical water.
My system specs:
HD5870 Crossfire with 10.8 ccc (latest drivers)
Win 7 64-bit
Not that it matters but i7 920 + 6gb RAM
I'm running all the setting at max. Tried different combinations with no luck..
edit: can't see the foliage of the willow tree until I cut it down.
