I'm pretty sure this is how Nvidia's game ready drivers work. They come with a bunch of pre-made profiles for popular video games, so the optimal settings are configured based on what applications are being executed, which is also why you have to let it scan for your games, so it knows what executables to watch for, so it can properly select the right profile to use.

My understanding is there's a certain amount of nvidia cleaning up after the game developers too. e.g. replacing poor performing shaders with optimised versions or just old-MS style "let's change how the driver works to keep the game working". Which is why they've been so resistant to opening the driver, they believe some of their perf advantage/secret sauce is in the driver rather than the hardware.

And that's why we have the "Game Ready" driver mess.
