Water reflections in linux client

[Arvenil]

I saw in gallery water reflections but in linux client i didnt found option for turning this on.

For example there are water reflections on this screenshot from gallery: http://download04.powerchallenge.com...shots/lake.jpg

But in linux client i have only ugly blue water. Is there an option to turn water reflections on in linux?

Iv'e got GF7600GS (galaxy), amd64 3k+

p.s. Thanks for suporting linux!
