When I switched from a laptop on november( i7 4770, gt750m, 12gb ram win 10) to my new system ( i7 7700, Gtx 1060 6gb, 16gb corsair LPX 3000, crucial mx300 500gb ssd,) I got worse performance. Since I run the precision xoc overlay, I notice that when my frames drop to the single digits, my gpu core clock drops to its lowest setting, around 1600mhz. I've tried all sorts of drivers, different oc settings. The one thing that helps, is using the "k" boost setting, which makes the gpu run at full power even when not needed. Even then I'll still get the fps drops, but it doesn't happen as much.
