How to change the graphics settings manually in the Crysis 2 demo

crysis-2

In the Crysis 2 Demo, there are only 3 graphics options (gamer, advanced, hardcore).
Can I change graphics options manually, like I could do in Crysis?

Things like environment detail, anti-aliasing, anisotrophic filtering, shader quality, shadow, motion blur and so on.

I found the answer in this thread, especially this post helped a lot. It's unpleasant for me to answer my own question, but there came no one to help.
