Hello!
i may not be a complete expert on FPS boosts, but I can give a few tips. But I need you to answer some questions.
1: What game are you trying to play?
2: Is your graphics driver up to date?
3: Is GeForce Experience installed?
4: What FPS are you running on those games?
5: What is your goal FPS?
After that, I can give you some tips. Thanks!
