He111,
On the page you show, come to the driver version line. At the right hand end you will see the square with the crossed emblem in it, click on that and it will open up the profile page.
At the top of that page it will show the profile version currently in use (usually it will show "Global" unless you change it ). At the right hand end of the profile panel there is a small downward pointing arrow, click on that and it will show all the current Nvidia profiles in alphabetical order. Unless you have already installed Luthier's code there will be no "Il2 Cliffs of Dover" profile showing. If you have installed it, but have updated the Nvidia drivers and not re-imported the "saved" profile it will have disappeared from the profile list. As I have said, there is no official support from Nvidia for "Il2 Cliffs of Dover" so every time you update your drivers you must re-import the profile from where you have saved it (I have made a new folder in My Documents called "C.o.D. Sli profile" and that is where I exported the copied profile to so that I can re-import it back into Nvidia Inspector when necessary).
Now comes the part that you will need to do. Install Luthier's Sli code.

This post will tell you how to do this. Remember, save any changes you make at the right hand side of the profile page (Apply Changes). If you have done everything correctly you will then find "Il2 Cliffs of Dover" listed on the profile page below the two current Il2 official profiles. Open up the profiles list from the Profiles panel at the top of the page and select "Il2 Cliffs of Dover" , the profile will show the coding supplied by Luthier, once again apply changes.
If you have trouble with this procedure I will be happy to help you.
