I have just played crysis 2 demo and i realized that there is no advanced graphics customization settings like in the first crysis so i hope that you will put that in crysis 2 as well cause i have low-end graphics card and i want to customiz the settings not just put every thing on low

Very likely it will be there. I think the demo is based off the beta, that's why it's missing right now.

Yes, in the final build.
