If you are talking about saving a new application profile from the settings you have made in the 3d gaming section..when you hit the save profile it goes to your computer programs....just scroll till you find the game folder (steam, eagames, origin, LFD, etc) open it and click on the exe file (application). Thats it. When that game is started, those settings will be applied. Remember to return your settings to the normal (ie web surfing) settings after you have made the 'application profile" or the settings you just made will be applied for everything. As an example, I use morfological rendering in some games...that would totally mess up my screen if I used it all the time. I made a preset for 'normal' 3D settings that will revert back to my basic set.
