Graphics FPS drops with core clock drops on Gtx 1080

So in few words. When playing GTA V or Rise of Tomb Raider, gpu usage, gpu clock, gpu voltages and fps drops for a second and then turns back. It drops once every maybe 2 hours. It is related to my hardware or software issue?
Here is screen from GPUZ during that spike i added black arrows and you can clearly see UTIL reason )




I checked event and this was not driver crash. 0 logs.


My pc:
Gigabyte Gtx 1080 Xtreme ( No OC ) ( good temps 60 C )
6700K No Oc ( good temps 55-60C )
16gb DDR4
Corsair 750 RM
SSD Bx 100 Crucial 256GB

I am on Windows 10 Anniversary Edition. Drivers 368.69.
PSU i think is fine, because i dont have random shutdowns and memtest86 passes fine.

 

Did this affect your enjoyment of the game at all?

 

Go to nvidia control panel > manage 3d settings,

Change: Multi-display/mixed-GPU acceleration. To: Single display performance mode (if you have more than one display or gpu leave this at default)

Change: Power management mode. To: Adaptive

Problem solved.

Would also update to the latest drivers: http://www.nvidia.co.uk/download/driverResults.aspx/108424/en-uk

 

No it didnt affect my enjoyment of the game, but i want to be sure that is not related to hardware.

 

As usual, it's drivers. See alfizzle's post above. Also, please, please, please start enjoying using your PC instead of worrying about it...!

 

...and you might have fewer problems with a legit version of Windows. This thread closed too.
