Gpu core clock and gpu usage drops in games - gpuz shows as util.

Hello. I have Gigabyte 1080 Xtreme. After upgrade to Windows Anniversary i have weird problem with fps spikes in GTA V and Rise of Tomb Raider.
In GTA V and Rise of Tomb Raider i am getting random fps dips for a second. During fps dip there is core clock drop for example from 1975mhz to 291mhz. During this moment there is GPU LOAD,Core clock and voltage drop.GPUZ shows as reason UTIL.

Here is screen from Rise of Tomb Raider ( i added black arrows and you can see util in this moment ):




In previous Windows version ( 1511 ) i dont had that problem.


My pc:
6700K stock no OC
Corsair 750 RM
16gb ram


Is this something with my hardware?

Downgrade your drivers to 368.xx or 369.xx. If that still doesn't work then revert to build 1511.

But i have already 368.69 installed drivers.

you will always see UTIL when the Card is not Boosting , that is basically what it means..... ie it is not UTILising the GPU fully.

Hopefully Dude's advice worked , it is how I usually set my 970 too ,especially as I am using a Custom Bios

Play an game after setting GPUz to log to file so you will catch the real reason eg VRel or Vop under Perf.Cap

If the Card has 2 plugs , use two different lines/wires direct from the PS , no splitters etc.

Use MSI AB to set the Power and Voltage Limits , see if that helps.
