Hello. I have an issue on GTA V and Rise of Tomb Raider, its very random. Sometimes its fine 5 hours, sometimes drop fps and gpu core clock for a fraction of a second and bring clocks back again. It happens when i am idling in game. Just standing by character in the same place in game without touching keyboard or mouse. It happen when i am standing only.

Screen,i added black arrows to show:

It drop for a second from 1985mhz to 1759mhz. UTIL gpuz. GPU LOAD 99% .What can it be? System clean, all programs closed, no spyware or anything weird in task manager. Windows 10 Anniversary. Newest drivers. Also i tried with 2 previous driver versions,didnt help.

PC: 6700K No Oc ( good temps )

Evga ACX 1080 ( good temps stable )

Corsair 750 RM

Asus Z170-P SSD

1x 256gb Crucial

It happens very rare. I can play 12 hours without this but sometimes it drop for one second when i am idling in game.

Power settings: Windows Power Settings: Balanced

Nvidia Power Management: Optimal

All power saver options OFF. Monitor turn off: Never, Sleep,Hibernate: Never

Any ideas? Is this related to Optimal power ? Any clues?

RBM.
