Very strange flickering problem

[Evotech 5]

Hey everybody,

 

since I´ve got this little problem for quite some time now I decided to join this forum to ask for some advice!

 

First of all the problem: 

When playing some games at 4K resolution (60Hz) I get a slight flickering when moving the camera.

This appears in games like Witcher 3, Far Cry 5, ...

It´s not a crazy flickering like the screen going black or colours being completely off, but it´s visible. 

I´d describe it like a slight change to a brighter screen and then back to normal, but very quick.

THIS ONLY APPEARS WHEN THE FRAMERATE GETS LOWER THAN 60 FPS!

In other games I don´t get this problem, especially when it´s running at 60FPS.

 

My Specs:

 

-Samsung KU6079 4K HDR TV being connected at 4K60Hz with a HDMI (Highspeed for the full 4K60 experience) 

 (Yes, I would love to use a Displayport cable but that´s not an option with this TV... and in general it works perfectly fine)

 

- 4790k at 4.4Ghz on all cores (ASUS MCE enabled) 

- Arctic freezer 33 Esports Edition

- ASUS H81 motherboard

- 16GB of 1600Mhz DDR3 RAM

- MSI GTX1070Ti (good temps, problem isn´t affected by overclocking)

- 600W PSU

 

- Windows 10 (64) Pro

- All drivers up to date by my knowledge, also NVIDIA drivers didn´t help so far

 

Greetings, 

Niklas
