I was looking already at lots of shader examples, most... or better like all are using PS1.4 which arent supported by Geforce cards.
Expecially Watershaders. The PS 1.4 does look really good, but it would suck to use that in your game since geforce users cant see them.

I was just wondering if the nice effects are possible with 1.1 - 1.3 as well.
Or has anyone any example for Geforce users ?.
