I just tried an older driver just to test some games stability. Turns out that the "nVidia FPS Limiter V3" also works on older nVidia drivers flawlessly with the new nVidia Inspector 184.108.40.206, which is strange. The option does not appear on the Control Panel; it only does on new drivers, but it does appear on the Inspector and works as intended. This is to let anyone know you DON'T need the new drivers to enjoy the new fps limiter, Inspector unlocks it for anyone. What a wonderful tool, to say the least. It just makes me a bit disappointed that so many driver options are literally hidden on other drivers and nVidia Inspector reveals them all and then nVidia comes up and presents them like if they were the latest innovation on gaming. Happy gaming!
