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

post #1 of 2
Thread Starter 
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:




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?

I believe it is because in the Win 10 AU update, MS upgraded WDDM (Windows Display Driver Model) from 2.0 -> 2.1. This has caused many driver incompatibility issues on nVidia and also AMD to my knowledge. MS has supposedly promised to work to deliver a fix, meanwhile graphics drivers cannot function properly (most Bethesda games, most notably fallout series, are now broken on nVidia drivers on AU).
