Stuttering: am I doing something wrong?

The game is one of the easiest games to run
I am running it at stable 60fps,my gpu is in idle mode(because it's that easy),and my cpu have its turbo disabled(so limited to 2.5ghz)and I also don't hear the fans which means,it's a easy job for the cpu

i7-6700HQ,GTX1060

Maybe it's your gpu or settings(the game don't have a lot of shadders to create)
