Random Fps?

[AliSafdar28]

Hello Guys, so i have this problem that i get random fps on Battlefield 4. The thing is that sometimes it goes up to 100fps and above and never drops below 65fps and stays that way for the entire session no matter how many matches i play (Avg=80-90fps). But when i close the game , play it the next day, there is a random chance if i would get that type of performance. If luck is not on my side , i get 40fps avg and peak 55 fps!. I always close mozilla firefox and random background things so i know they are not the problem here.

 

Specs:

 

Intel i5 4200M @2.5Ghz
Nvidia Gt 740m
8GB RAM

You might be thinking that there is no possible way that I am getting that performance on that kind of system(laptop). Well ever since i upgraded to Win10 , things have changed. And i am running things on Low with 75% Resolution scale so yeah. It's "random" (the fps) and i would really appreciate some help. It doesn't happen always but it really annoys me when it does. I have tried it with different maps and game modes and i know they are not the problem here , i played 32 player TDM on a map and got 100fps one time and played the same thing over again and got 40 fps the other time.
