Giovanni, The biggest problem with the 3d clouds is they take up a ton of texture ram. Most likely that is the primary bottle neck you are seeing with your 16Mb card. I've had trouble even with a 32Mb card, so if you really want nice 3d clouds (they aren't fully finished yet unfortunately) you probably want to upgrade to a 64Mb graphics card.
