Anytime your computer just barely meets the minimum req's you're not going to have very smooth gameplay. Throw in that its an EA game, and an open world survival at that and you're going to start to have even more problems when you build/over-build in an area. The fact that you have a laptop also makes this worse.
Realistically, unless you plan to get a new laptop/computer with higher specs, you're going to run into this problem with most games. So either upgrade or learn to live with it.
I'm running on a 1070ti and i have no problems out in the world, but i have overbuilt my base area and get horrible fps dips, but i love the game so just live with it. Until i can actually buy the parts for a new machine that is, which at this point seems like it'll never happen.
