How to fix the sudden random FPS drops in ArmA 3?

[Maq___]

Hi to all,
I face huge FPS drops while playing ArmA 3,from 70+ FPS to 30 or less,and then back to 70+ and then again sudden random FPS drops to 30 or less!
And this happens even when playing on lowest settings!

My Lenovo Y-700-15ISK laptop's specs are:
i7-6700 HQ CPU,16 GB DRR4 RAM.and Nvidia GTX 960M 4 GB GDDR5 GPU,and Win 10 x64 bit OS.

Please help me to somehow fix these FPS drops!

Thanks in advance!
Best regards!

From what I've heard and seen, ArmA 3 is not very well optimized. It's designed for huge maps with dozens of things going on all at once, but it's not exactly coded to do that very well.

It could easily be just that you're on a GTX 960M, or it could be something else. I get occasional lagspikes on my desktop 980Ti.
