almost every game I've encountered that has a "launcher" program, the launcher is almost always a "stub" program that runs another program, usually after a few Anti-piracy and CD checks and so forth. So when you have the games running, see what their processes show up as in task manager to be sure that they are really "launcher.exe", and not some other program. If they <is> called launcher.exe, you could try renaming them to a more descriptive name and see if that works- then you can add it to Nvidia control panel.
One more thing about NVidia control panel:
Unless you have a specific reason to tweak the lower level settings (CUDA, Extension String length limit, Max pre-rendered frames, Multi-display ,etc), it is usually better (and far less stressful
) to simply change the configurations in-game.
