any suggestions?

There's not much you can do about your pixel shader version afaik... if the game doesn't work around it, you need a more up-to-date graphics card. Don't know why it complains about system & video card memory, though.

what exactly is pixel shader?

nVidia has a small text about pixel shaders on their site: http://www.nvidia.com/object/feature_pixelshader.html

pixel shader is whats used to create the water.

In a nut shell, you need to invest in a new, more powerful video card and some more RAM.

Can u post exactly your config..so we can give you what is sweet spot..otherwise..try to update drivers...for ALL equipment i.e. motherboard,SVGA,Audio,SATA,etc....
