Make water look real (Not transparrent)

Hi guys. i just got Unity Pro and made a terrain. I made a plane and added PRO water script and effect to it, but it still looks like “glass Water” How can i make it look more real? Like in the island demo, the waer has the blu-ish/green colour mine is just, plane. and if i add colour to it, it will be “colour” transparent. I am basically asking how to make water look like in the island demo. My computer does not have a graphics card, or pixel shader technology:(, so it cant render shadows. Can this be the treason tho for the water problem?:face_with_spiral_eyes:

Yes, I’d highly recommend getting a new computer, or at least a new graphics card.
