@ All: I wrote an e-mail to Mike reguarding the fluids and some other things/commands that I found "unfunctional" or "missbehaving". I thought I should let you all know what he said!
(This was also posted in the Update-thread!)
Here is my question to him reguarding the fluids-issue:
Many people have problems with the fluids showing up correctly! While the included demo in the NVidia-PhysX-Driver/-Systemsoftware works absolute fine, the compiled fluid-demo for the competition included with the update doesn't show up for many like a "real" fluid! It only looks like spheares bouncing around and not like a connected surface! Also I'm unsure if you can change their color, cause somehow they are hard to see, cause of the fluid-particle-transparency? It was also mentioned that the visibility is only possible at special viewing-angles! (See the following thread for more replys:)

Here is what he told me about the "Fluids":
I get the same problem with fluids. So far only known it to work on 8800 cards. It's something we need to fix. I will check it out.
