Dayz flicker effect and color particles

[Lisa97 0]

Good day

I have the following problem

In the game there is always a flicker that comes close to blinking. The picture gets darker and darker for a short time in between. However, this does not always occur. Sometimes it comes more and more often. But sometimes it's gone for a while. We watched the whole thing in one broadcast. It was also visible there, which enabled us to rule out a hardware problem. Because normally it would not be visible in a transmission, it would be a hardware problem. However, only I have this problem. Friends of mine don't have this. At the same time, I noticed that several colored particles were visible when a helicopter crashed. Also visible in the transmission. I've only had this in Dayz so far. We also tested this in games like Scum and Atlas. This did not happen there.
We thought long and hard about what could be causing this, but couldn't find anything. Also not on the internet

Hardware:
Intel I7 9700K
Asus rog strix z390-f gaming
Asus rog strix gtx 1080 ti
2666mhz ram
850 watt power supply from Be quiet

I hope for possible solutions.

My English is rather poor, so I use Google translator. So please don't excuse the bad translation
