3dmark 11 High temple - random fps drop on 1080 ti in the same spot.

[sew999]

Hi. I am getting weird single stutter/fps drop in 3dmark 11 HIGH TEMPLE demo on extreme details. It will stutter always on the same spot. Drop ( for a 1 second ) from 60 fps to 50 fps and back again to 60fps.
It happens very randomly but on the same spot in test. Some runs are without this drop, but sometimes it will drop exactly on the same spot in benchmark. Sometimes it will run fine 10 runs without drop on the same spot, sometimes it drop there after 1 or 2 run.
And exactly on the same spot in benchmark. I post screen,fps drop place:

My pc: 6700K stock ( normal temps ), 1080 ti reference ( 80C normal temps ). So its not thermal throttling.

I checked gpu clock during that spike,and clock are normal. There is only gpu load drop for 1 second.
Ah i almost forgot.
I was using the Gigabyte Xtreme Gtx 1080 graphics before and this never happened. I moved up to the new 1080 ti and this strange issue is happening.
Any ideas? Weird huh?

Using Windows 10 . Drivers 378.92 . 3dmark 11 1.0.2
