I upgraded my build from a 960 2gb to an EVGA 1060 SSC 6gb. I used the geforce experience "optimal" settings and played Rise of the Tomb Raider. Looked amazing, however, it would stutter in certain parts, and freeze during gameplay. When it does this, I saw that my CPU was maxed out at %100, my keyboard has a display that keeps track of my RAM and CPU. I keep reading that a 1060 shouldn't be bottlenecked by a 4590, if that's the case, then a) what is causing the stuttering and freezing, (could it be my new dell freesync monitor?) b) what is causing the CPU to be tapped out.
