It sounds like you are using nVidia's so-called "optimus" technology, their solution to hybrid graphics.
If that's indeed the case, you should notice Linux has no native way to deal with these hybrid graphics. Your system will leave both adapters powered on while using one (generally your Intel integrated graphics), which is most probably the reason why you see such a message when trying to run an intensive 3D application.
In order to be able to correctly "switch" to the right adapter, you will need a special application like Bumblebee. In a nutshell, installation is as simple as the following 3 lines (after which a reboot will be needed):
sudo add-apt-repository ppa:bumblebee/stable
sudo apt-get update
sudo apt-get install bumblebee bumblebee-nvidia
However, before proceeding, I recommend you to take a look at the Bumblebee site for more information: http://bumblebee-project.org/install.html.
Once bumblebee is installed, your system will keep using your intel graphics by default, but you'll be able to run an application using your dedicated nvidia card with the following command:
In your case, you want to run Crysis, which is loaded through wine. The command will look like this (assuming you're in the Crysis2 directory):
optirun wine crysis2.exe
