After you're done, you will get fp "Illegal Module" error. Don't worry, you'll just have to wait day-two till shifty will fix this. But if you are about to play cupwar in next couple days, I wouldn't start doing this. (Hi to indOsteelo aka. Mr. I be fun cause i eat drugs instead of mommys soup)
If you are lazy to waste 15 mins to follow all the steps Accurately, please don't even start. Thank you.
1. Go to nvidia site (nvidia.com) and download latest drivers. Install them. Restart pc.
2. Now go to http://www.nhancer.com/ and download latest Nhancer. Install it. It might ask some questions, just press ok. Don't worry it's very handy and pretty known program to setup driver settings.
3. Now open nHancer. Go to "Filter the list of profiles", Predefined Profiles and set "All" there. SCREENSHOT FOR NEWBS
Now you can see huge list of games. Search soldier of fortune 2: double helix. After you press on it, you should see executables list under. Press "Add an executable file" button. Now for executable browse to sof2mp-test.exe and for launcher browse to fairplay.exe and press OK. SCREENSHOT FOR NEWBS 2
Now again go to "Filter the list of profiles", Predefined Profiles and set back to "of installed applications".
4. Now you should see "Soldier of Fortune 2: Double Helix" in your applications list (if you don't, then restart nHancer). Press on it, go to "Compability" (upper-right corner, under "Profile"), then go to "OpenGL" and turn on "Driver extension limit" and type "11a8" there.

5. (This part is necessary for those who want to make their sof look smoother, sof will work without this part anyway) If you have pretty much ok pc, you can try anti-aliasing (you should try it anyway
Screenshot for dummies: Screenshot #2
Here's the screenshot with all settings maxed, resolution 1280x1024 and forced 16xQ AA with nHancer (you can notice that there are no annoying ladders all over the textures):

Sorry for english mistakes in advance.
Edit:
There is no need to keep nHancer opened after all that.
