Can't get shaders to work = crappy looking water and landscape

[Camil]

I got a high-end comp last week, so I could play The Sims 2&3 flawlessly.(And some other games in future.)

Anyhow, now The Sims 2 isn't working properly. The water is nontransparent blue and landscape looks.. well ugly :).
The problem seems to be that the shaders and some other advanced graphical features aren't working.
After 3hours of intensive googling and trying things like: http://www.modthesims.info/wiki.php?title=Game_Help:Bump_Maps_and_Shaders im getting hopeless.

Anyone who's had similar problems or knows something about this please reply.

Try updating your graphics driver (http://www.modthesims.info/wiki.php?title=Game_Help:Graphics_Cards#Downloading_New_Graphics_Drivers). As mentioned in that wiki, you might also want to try deleting My documents/ EA Games/ The Sims2/ Config/ userprops.xml

It didn't help.
